Pull request #2044 (2024-02-20 08:42:50)

new feature: AgentSet.get can retrieve one or more then one attribute
This adds a small additional feature to AgentSet. The get method now takes a string or list of strings. This allows you to retrieve multiple attributes in one go. I also added a test to cover this new feature.

+# Contributing
+
+As an open source project, Mesa welcomes contributions of many forms, and from beginners to experts. If you are
+curious or just want to see what is happening, we post our development session agendas
+and development session notes on [Mesa discussions]. We also have a threaded discussion forum on [Matrix]
+for casual conversation.
+
+In no particular order, examples include:
+
+- Code patches
+- Bug reports and patch reviews
+- New features
+- Documentation improvements
+- Tutorials
+
+No contribution is too small. Although, contributions can be too big, so let's
+discuss via [Matrix] OR via [an issue].
+
+**To submit a contribution**
+
+- Create a ticket for the item that you are working on.
+- Fork the Mesa repository.
+- [Clone your repository] from Github to your machine.
+- Create a new branch in your fork: `git checkout -b BRANCH_NAME`
+- Run `git config pull.rebase true`. This prevents messy merge commits when updating your branch on top of Mesa main branch.
+- Install an editable version with developer requirements locally: `pip install -e ".[dev]"`
+- Edit the code. Save.
+- Git add the new files and files with changes: `git add FILE_NAME`
+- Git commit your changes with a meaningful message: `git commit -m "Fix issue X"`
+- If implementing a new feature, include some documentation in docs folder.
+- Make sure that your submission works with a few of the examples in the examples repository. If adding a new feature to mesa, please illustrate usage by implementing it in an example.
+- Make sure that your submission passes the [GH Actions build]. See "Testing and Standards below" to be able to run these locally.
+- Make sure that your code is formatted according to [the black] standard (you can do it via [pre-commit]).
+- Push your changes to your fork on Github: `git push origin NAME_OF_BRANCH`.
+- [Create a pull request].
+- Describe the change w/ ticket number(s) that the code fixes.
+- Format your commit message as per [Tim Pope's guideline].
+
+## Testing and Code Standards
+
+```{image} https://codecov.io/gh/projectmesa/mesa/branch/main/graph/badge.svg
+:target: https://codecov.io/gh/projectmesa/mesa
+```
+
+```{image} https://img.shields.io/badge/code%20style-black-000000.svg
+:target: https://github.com/psf/black
+```
+
+As part of our contribution process, we practice continuous integration and use GH Actions to help enforce best practices.
+
+If you're changing previous Mesa features, please make sure of the following:
+
+- Your changes pass the current tests.
+- Your changes pass our style standards.
+- Your changes don't break the models or your changes include updated models.
+- Additional features or rewrites of current features are accompanied by tests.
+- New features are demonstrated in a model, so folks can understand more easily.
+
+To ensure that your submission will not break the build, you will need to install Ruff and pytest.
+
+```bash
+pip install ruff pytest pytest-cov
+```
+
+We test by implementing simple models and through traditional unit tests in the tests/ folder. The following only covers unit tests coverage. Ensure that your test coverage has not gone down. If it has and you need help, we will offer advice on how to structure tests for the contribution.
+
+```bash
+py.test --cov=mesa tests/
+```
+
+With respect to code standards, we follow [PEP8] and the [Google Style Guide]. We use [ruff format] (a more performant alternative to `black`) as an automated code formatter. You can automatically format your code using [pre-commit], which will prevent `git commit` of unstyled code and will automatically apply black style so you can immediately re-run `git commit`. To set up pre-commit run the following commands:
+
+```bash
+pip install pre-commit
+pre-commit install
+```
+
+You should no longer have to worry about code formatting. If still in doubt you may run the following command. If the command generates errors, fix all errors that are returned.
+
+```bash
+ruff .
+```

+# Best Practices
+
+Here are some general principles that have proven helpful for developing models.
+
+## Model Layout
+
+A model should be contained in a folder named with lower-case letters and
+underscores, such as `thunder_cats`. Within that directory:
+
+- `README.md` describes the model, how to use it, and any other details.
+  Github will automatically show this file to anyone visiting the directory.
+- `model.py` should contain the model class.  If the file gets large, it may
+  make sense to move the complex bits into other files, but this is the first
+  place readers will look to figure out how the model works.
+- `server.py` should contain the visualization support, including the server
+  class.
+- `run.py` is a Python script that will run the model when invoked via
+  `mesa runserver`.
+
+After the number of files grows beyond a half-dozen, try to use sub-folders to
+organize them. For example, if the visualization uses image files, put those in
+an `images` directory.
+
+The [Schelling](https://github.com/projectmesa/mesa-examples/tree/main/examples/schelling) model is
+a good example of a small well-packaged model.
+
+It's easy to create a cookiecutter mesa model by running `mesa startproject`
+
+## Randomization
+
+If your model involves some random choice, you can use the built-in `random`
+property that Mesa `Model` and `Agent` objects have. This works exactly
+like the built-in `random` library.
+
+```python
+class AwesomeModel(Model):
+  # ...
+
+  def cool_method(self):
+    interesting_number = self.random.random()
+    print(interesting_number)
+
+class AwesomeAgent(Agent):
+  # ...
+  def __init__(self, unique_id, model, ...):
+    super().__init__(unique_id, model)
+    # ...
+
+  def my_method(self):
+    random_number = self.random.randint(0, 100)
+```
+
+(The agent's random property is just a reference to its parent model's
+`random` property).
+
+When a model object is created, its random property is automatically seeded
+with the current time. The seed determines the sequence of random numbers; if
+you instantiate a model with the same seed, you will get the same results.
+To allow you to set the seed, make sure your model has a `seed` argument in its
+constructor.
+
+```python
+class AwesomeModel(Model):
+
+  def __init__(self, seed=None):
+    pass
+
+  def cool_method(self):
+    interesting_number = self.random.random()
+    print(interesting_number)
+
+>>> model0 = AwesomeModel(seed=0)
+>>> model0._seed
+0
+>>> model0.cool_method()
+0.8444218515250481
+>>> model1 = AwesomeModel(seed=0)
+>>> model1.cool_method()
+0.8444218515250481

+# How-to Guide
+
+This guide provides concise instructions and examples to help you start with common tasks in Mesa.
+
+## Models with Discrete Time
+
+For models involving agents of multiple types, including those with a time attribute, you can construct a discrete-time model. This setup allows each agent to perform actions in steps that correspond to the model's discrete time.
+
+Example:
+```python
+if self.model.schedule.time in self.discrete_time:
+    self.model.space.move_agent(self, new_pos)
+```
+
+## Implementing Model-Level Functions with Staged Activation
+
+In staged activation scenarios, to designate functions that should only operate
+at the model level (and not at the agent level), prepend the function name with
+"model." in the function list definition. This approach is useful for
+model-wide operations, like adjusting a wage rate based on demand.
+
+Example:
+```python
+stage_list = [Send_Labour_Supply, Send_Labour_Demand, model.Adjust_Wage_Rate]
+self.schedule = StagedActivation(self, stage_list, shuffle=True)
+```
+
+## Using `numpy.random`
+
+To incorporate `numpy`'s random functions, such as for generating a Poisson
+distribution, initialize a random number generator in your model's constructor.
+
+Example:
+```python
+import mesa
+import numpy as np
+
+class MyModel(mesa.Model):
+    def __init__(self, seed=None):
+        super().__init__()
+        self.random = np.random.default_rng(seed)
+```
+
+Usage example:
+```python
+lambda_value = 5
+sample = self.random.poisson(lambda_value)
+```

+## Multi-process `batch_run` on Windows
+
+When using `batch_run` with `number_processes = None` on Windows, you might
+encounter progress display issues or `AttributeError: Can't get attribute
+'MoneyModel' on <module '__main__' (built-in)>`. To resolve this, run
+your code outside of Jupyter notebooks and use the following pattern,
+incorporating `freeze_support()` for multiprocessing support.
+
+Example:
+```python
+from mesa.batchrunner import batch_run
+from multiprocessing import freeze_support
+
+params = {"width": 10, "height": 10, "N": range(10, 500, 10)}
+
+if __name__ == '__main__':
+    freeze_support()
+    results = batch_run(
+        MoneyModel,
+        parameters=params,
+        iterations=5,
+        max_steps=100,
+        number_processes=None,
+        data_collection_period=1,
+        display_progress=True,
+    )
+```
+
+If you would still like to run your code in Jupyter, adjust your code as
+described and consider integrating external libraries like
+[nbmultitask](https://nbviewer.org/github/micahscopes/nbmultitask/blob/39b6f31b047e8a51a0fcb5c93ae4572684f877ce/examples.ipynb)

-How-to Guide
-============
-
-Here you can find code that allows you to get to get started on common tasks in Mesa.
-
-Models with Discrete Time
--------------------------
-If you have `Multiple` type agents and one of them has time attribute you can still build a model that is run by discrete time. In this example, each step of the model, and the agents have a time attribute that is equal to the discrete time to run its own step.
-
-.. code:: python
-
-  if self.model.schedule.time in self.discrete_time:
-      self.model.space.move_agent(self, new_pos)
-
-Implementing Model Level Functions in Staged Activation
--------------------------------------------------------
-In staged activation, if you may want a function to be implemented only on the model level and not at the level of agents.
-For such functions, include the prefix "model." before the model function name, when defining the function list.
-For example, consider a central employment exchange which adjust the wage rate common to all laborers
-in the direction of excess demand.
-
-.. code:: python
-    stage_list=[Send_Labour_Supply, Send_Labour_Demand, model.Adjust_Wage_Rate]
-    self.schedule = StagedActivation(self,stage_list,shuffle=True)
-
-Using ```numpy.random```
--------------
-
-Sometimes you need to use ``numpy``'s ``random`` library, for example to get a Poisson distribution.
-
-.. code:: python
-
-  class MyModel(Model):
-      def __init__(self, ...):
-          super().__init__()
-          self.random = np.random.default_rng(seed)
-
-And just use `numpy`'s random as usual, e.g. ``self.random.poisson()``.
-
-Using multi-process ```batch_run``` on Windows
--------------
-
-You will have an issue with `batch_run` and `number_processes = None`. Your cell will
-show no progress, and in your terminal you will receive *AttributeError: Can't get attribute 'MoneyModel' on
-<module '__main__' (built-in)>*. One way to overcome this is to take your code outside of Jupyter and adjust the above
-code as follows.
-
-
-.. code:: python
-
-    from multiprocessing import freeze_support
-
-    params = {"width": 10, "height": 10, "N": range(10, 500, 10)}
-
-    if __name__ == '__main__':
-        freeze_support()
-        results = batch_run(
-                MoneyModel,
-                parameters=params,
-                iterations=5,
-                max_steps=100,
-                number_processes=None,
-                data_collection_period=1,
-                display_progress=True,
-        )
-
-
-If you would still like to run your code in Jupyter you will need to adjust the cell as noted above. Then you can
-you can add the `nbmultitask library <(https://nbviewer.org/github/micahscopes/nbmultitask/blob/39b6f31b047e8a51a0fcb5c93ae4572684f877ce/examples.ipynb)>`__
-or look at this `stackoverflow <https://stackoverflow.com/questions/50937362/multiprocessing-on-python-3-jupyter>`__.

 For example, suppose for a Schelling model, we want to draw all agents
 as circles; red ones for the majority (agent type=0), and blue ones for
 the minority (agent type=1). The function to do this might look like
 this:

-            else:

+# Mesa Overview
 
 Mesa is a modular framework for building, analyzing and visualizing agent-based models.
 
 **Agent-based models** are computer simulations involving multiple entities (the agents) acting and interacting with one another based on their programmed behavior. Agents can be used to represent living cells, animals, individual humans, even entire organizations or abstract entities. Sometimes, we may have an understanding of how the individual components of a system behave, and want to see what system-level behaviors and effects emerge from their interaction. Other times, we may have a good idea of how the system overall behaves, and want to figure out what individual behaviors explain it. Or we may want to see how to get agents to cooperate or compete most effectively. Or we may just want to build a cool toy with colorful little dots moving around.

-Modeling modules
-~~~~~~~~~~~~~~~~
+### Modeling modules
 
 Most models consist of one class to represent the model itself; one class (or more) for agents; a scheduler to handle time (what order the agents act in), and possibly a space for the agents to inhabit and move through. These are implemented in Mesa's modeling modules:
 
-* ``mesa.Model``, ``mesa.Agent``
-* `mesa.time <apis/time.html>`_
-* `mesa.space <apis/space.html>`_
+- `mesa.Model`, `mesa.Agent`
+- [mesa.time](apis/time.html)
+- [mesa.space](apis/space.html)
 
 The skeleton of a model might look like this:
 
-.. code:: python
-
-    import mesa
-
-    class MyAgent(mesa.Agent):
-        def __init__(self, name, model):
-            super().__init__(name, model)
-            self.name = name
-
-        def step(self):
-            print("{} activated".format(self.name))
-            # Whatever else the agent does when activated
-
-    class MyModel(mesa.Model):
-        def __init__(self, n_agents):
-            super().__init__()
-            self.schedule = mesa.time.RandomActivation(self)
-            self.grid = mesa.space.MultiGrid(10, 10, torus=True)
-            for i in range(n_agents):
-                a = MyAgent(i, self)
-                self.schedule.add(a)
-                coords = (self.random.randrange(0, 10), self.random.randrange(0, 10))
-                self.grid.place_agent(a, coords)
-
-        def step(self):
-            self.schedule.step()
+```python
+import mesa
+
+class MyAgent(mesa.Agent):
+    def __init__(self, name, model):
+        super().__init__(name, model)
+        self.name = name
+
+    def step(self):
+        print("{} activated".format(self.name))
+        # Whatever else the agent does when activated
+
+class MyModel(mesa.Model):
+    def __init__(self, n_agents):
+        super().__init__()
+        self.schedule = mesa.time.RandomActivation(self)
+        self.grid = mesa.space.MultiGrid(10, 10, torus=True)
+        for i in range(n_agents):
+            a = MyAgent(i, self)
+            self.schedule.add(a)

+            self.grid.place_agent(a, coords)
+
+    def step(self):
+        self.schedule.step()
+```
 
 If you instantiate a model and run it for one step, like so:
 
-.. code:: python
+```python
+model = MyModel(5)
+model.step()
+```
 
-    model = MyModel(5)
-    model.step()

-Analysis modules
-~~~~~~~~~~~~~~~~
+### Analysis modules
 
 If you're using modeling for research, you'll want a way to collect the data each model run generates. You'll probably also want to run the model multiple times, to see how some output changes with different parameters. Data collection and batch running are implemented in the appropriately-named analysis modules:
 
-* `mesa.datacollection <apis/datacollection.html>`_
-* `mesa.batchrunner <apis/batchrunner.html>`_
+- [mesa.datacollection](apis/datacollection.html)
+- [mesa.batchrunner](apis/batchrunner.html)
 
 You'd add a data collector to the model like this:
 
-.. code:: python
-
-    import mesa
+```python
+import mesa
 
-    # ...
+# ...
 
-    class MyModel(mesa.Model):
-        def __init__(self, n_agents):
-            # ...
-            self.dc = mesa.DataCollector(model_reporters={"agent_count":
-                                        lambda m: m.schedule.get_agent_count()},
-                                    agent_reporters={"name": lambda a: a.name})
+class MyModel(mesa.Model):
+    def __init__(self, n_agents):
+        # ...
+        self.dc = mesa.DataCollector(model_reporters={"agent_count":
+                                    lambda m: m.schedule.get_agent_count()},
+                                agent_reporters={"name": lambda a: a.name})
 
-        def step(self):
-            self.schedule.step()
-            self.dc.collect(self)
+    def step(self):
+        self.schedule.step()
+        self.dc.collect(self)
+```
 
-The data collector will collect the specified model- and agent-level data at each step of the model. After you're done running it, you can extract the data as a `pandas <http://pandas.pydata.org/>`_ DataFrame:
-
-.. code:: python
-
-    model = MyModel(5)
-    for t in range(10):
-        model.step()
-    model_df = model.dc.get_model_vars_dataframe()
-    agent_df = model.dc.get_agent_vars_dataframe()
+The data collector will collect the specified model- and agent-level data at each step of the model. After you're done running it, you can extract the data as a [pandas](http://pandas.pydata.org/) DataFrame:

+for t in range(10):
+    model.step()
+model_df = model.dc.get_model_vars_dataframe()
+agent_df = model.dc.get_agent_vars_dataframe()
+```
 
 To batch-run the model while varying, for example, the n_agents parameter, you'd use the `batch_run` function:
 
-.. code:: python
-
-    import mesa
-
-    parameters = {"n_agents": range(1, 20)}
-    mesa.batch_run(
-        MyModel,
-        parameters,
-        max_steps=10,
-    )
+```python
+import mesa
 
+parameters = {"n_agents": range(1, 20)}
+mesa.batch_run(
+    MyModel,
+    parameters,
+    max_steps=10,
+)
+```
 
 As with the data collector, once the runs are all over, you can extract the data as a data frame.
 
-.. code:: python
+```python
+batch_df = batch_run.get_model_vars_dataframe()
+```
 
-    batch_df = batch_run.get_model_vars_dataframe()
-
-
-Visualization modules
-~~~~~~~~~~~~~~~~~~~~~
+### Visualization modules
 
 Finally, you may want to directly observe your model as it runs. Mesa's main visualization tool uses a small local web server to render the model in a browser, using JavaScript. There are different components for drawing different types of data: for example, grids for drawing agents moving around on a grid, or charts for showing how some data changes as the model runs. A few core modules are:
 
-* mesa.visualization.ModularVisualization
-* mesa.visualization.modules
+- mesa.visualization.ModularVisualization
+- mesa.visualization.modules
 
 To quickly spin up a model visualization, you might do something like:
 
-.. code:: python
-
-    import mesa
-
-    def agent_portrayal(agent):
-        portrayal = {"Shape": "circle",
-                     "Filled": "true",
-                     "Layer": 0,
-                     "Color": "red",
-                     "r": 0.5}
-        return portrayal
-
-    grid = mesa.visualization.CanvasGrid(agent_portrayal, 10, 10, 500, 500)
-    server = mesa.visualization.ModularServer(MyModel,
-                           [grid],
-                           "My Model",
-                           {'n_agents': 10})
-    server.launch()
+```python
+import mesa
+
+def agent_portrayal(agent):
+    portrayal = {"Shape": "circle",
+                 "Filled": "true",
+                 "Layer": 0,
+                 "Color": "red",
+                 "r": 0.5}
+    return portrayal
+
+grid = mesa.visualization.CanvasGrid(agent_portrayal, 10, 10, 500, 500)
+server = mesa.visualization.ModularServer(MyModel,
+                       [grid],
+                       "My Model",
+                       {'n_agents': 10})
+server.launch()
+```
 
 This will launch the browser-based visualization, on the default port 8521.

-"How To" Mesa Packages
-======================
+# "How To" Mesa Packages
 
 The Mesa core functionality is just a subset of what we believe researchers creating Agent Based Models (ABMs) will use. We designed Mesa to be extensible, so that individuals from various domains can build, maintain, and share their own packages that work with Mesa in pursuit of "unifying algorithmic theories of the relation between adaptive behavior and system complexity (Volker Grimm et al 2005)."
 
 **DRY Principle**
 
-This decoupling of code to create building blocks is a best practice in software engineering. Specifically, it exercises the `DRY principle (or don't repeat yourself) <https://en.wikipedia.org/wiki/Don%27t_repeat_yourself>`_ (Hunt and Thomas 2010). The creators of Mesa designed Mesa in order for this principle to be exercised in the development of agent-based models (ABMs). For example, a group of health experts may create a library of human interactions on top of core Mesa. That library then is used by other health experts. So, those health experts don't have to rewrite the same basic behaviors.
+This decoupling of code to create building blocks is a best practice in software engineering.

For example, a group of health experts may create a library of human interactions on top of core Mesa. That library then is used by other health experts. So, those health experts don't have to rewrite the same basic behaviors.
 
 **Benefits to Scientists**
 
 Besides a best practice of the software engineering community, there are other benefits for the scientific community.
 
 1. **Reproducibility and Replicability.** Decoupled shared packages also allows for reproducibility and replicability. Having a package that is shared allows others to reproduce the model results. It also allows others to apply the model to similar phenomenon and replicate the results over a diversity of data. Both are essential part of the scientific method (Leek and Peng 2015).
-
 2. **Accepted truths.** Once results are reproduced and replicated, a library could be considered an accepted truth, meaning that the community agrees the library does what the library intends to do and  the library can be trusted to do this. Part of the idea behind 'accepted truths' is that subject matter experts are the ones that write and maintain the library.
-
 3. **Building blocks.** Think of libraries like Legos. The researcher can borrow a piece from here or there to pull together the base of their model, so they can focus on the value add that they bring. For example, someone might pull from a human interactions library and a decision-making library and combine the two to look at how human cognitive function effects the physical spread of disease.
 
 **Mesa and Mesa Packages**
 
 Because of the possibilities of nuanced libraries, few things will actually make it into core Mesa. Mesa is intended to only include core functionality that everyone uses. However, it is not impossible that something written on the outside is brought into core at a later date if the value to everyone is proven through adoption.
 
-An example that is analogous to Mesa and Mesa packages is `Django <https://www.djangoproject.com/>`_ and `Django Packages <https://djangopackages.org/>`_. Django is a web framework that allows you to build a website in Python, but there are lots of things besides a basic website that you might want. For example, you might want authentication functionality. It would be inefficient for everyone to write their own authentication functionality, so one person writes it (or a group of people). They share it with the world and then many people can use it.

They share it with the world and then many people can use it.
 
 This process isn't perfect. Just because you write something doesn't mean people are going to use it. Sometimes two different packages will be created that do similar things, but one of them does it better or is easier to use. That is the one that will get more adoption. In the world of academia, often researchers hold on to their content until they are ready to publish it. In the world of open source software, this can backfire. The sooner you open source something the more likely it will be a success, because you will build consensus and engagement. Another thing that can happen is that while you are working on perfecting it, someone else is building in the open and establishes the audience you were looking for. So, don't be afraid to start working directly out in the open and then release it to the world.

 There are two sections in this documentation. The first is the User Guide, which is aimed at users of packages. The section is a package development guide, which is aimed at those who want to develop packages. Without further ado, let's get started!

 **Step 1: Select a package**
 
-Currently, a central list of compatible packages is located on the `Mesa Wiki Packages Page <https://github.com/projectmesa/mesa/wiki/Mesa-Packages>`_.

 **Step 2: Establish an environment**
 
 Create a virtual environment for the ABM you are building. The purpose of a virtual environment is to isolate the packages for your project from other projects. This is helpful when you need to use two different versions of a package or if you are running one version in production but want to test out another version. You can do with either virtualenv or Anaconda.

 **Step 3: Install the packages**
 
 Install the package(s) into your environment via pip/conda or GitHub. If the package is a mature package that is hosted in the Python package repository, then you can install it just like you did Mesa:
 
-   .. code:: bash
-
-      pip install package_name
+> ```bash
+> pip install package_name
+> ```
 
 However, sometimes it takes a little bit for projects to reach that level of maturity. In that case to use the library, you would install from GitHub (or other code repository) with something like the following:
 
-
-   .. code:: bash
-
-      pip install https://github.com/<path to project>
+> ```bash
+> pip install https://github.com/<path to project>
+> ```
 
 The commands above should also work with Anaconda, just replace the `pip` with `conda`.

-Package Development: A "How-to Guide"
---------------------------------------------------
+## Package Development: A "How-to Guide"
 
 The purpose of this section is help you understand, setup, and distribute your Mesa package as quickly as possible. A Mesa package is just a Python package or repo. We just call it a Mesa package, because we are talking about a Python package in the context of Mesa. These instructions assume that you are a little familiar with development, but that you have little knowledge of the packaging process.
 
 There are two ways to share a package:
 
-   1. Via GitHub or other service (e.g. GitLab, Bitbucket, etc.)
-   2. Via PyPI, the Python package manager
+> 1. Via GitHub or other service (e.g. GitLab, Bitbucket, etc.)
+> 2. Via PyPI, the Python package manager
 
 Sharing a package via PyPI make it easier to install for users but is more overhead for whomever is maintaining it. However, if you are truly intending for a wider/longer-term adoption, then PyPI should be your goal.
 
 Most likely you created an ABM that has the code that you want to share in it, which is what the steps below describe.
 
-
 **Sharing your package**
 
-
-   1. Layout a new file structure to move the code into and then make sure it is callable from Mesa, in a simple, easy to understand way. For example, ``from example_package import foo``.  See `Creating the Scaffolding <https://python-packaging.readthedocs.io/en/latest/minimal.html#creating-the-scaffolding>`_.
-
-   2. `Pick a name <https://python-packaging.readthedocs.io/en/latest/minimal.html#picking-a-name>`_.
-
-   3. `Create a repo on GitHub <https://help.github.com/articles/create-a-repo/>`_.
-
-      * Enter the name of the repo.
-      * Select a license (not sure-- click the blue 'i' next to the i for a great run down of licenses). We recommend something permissive Apache 2.0, BSD, or MIT so that others can freely adopt it. The more permissive the more likely it will gain followers and adoption. If you do not include a license, it is our belief that you will retain all rights, which means that people can't use your project, but it should be noted that we are also not lawyers.
-      * Create a readme.md file (this contains a description of the package) see an example: `Bilateral Shapley <https://github.com/tpike3/bilateralshapley/blob/master/README.md>`_
-
-   4. `Clone the repo to your computer <https://help.github.com/articles/cloning-a-repository/#platform-linux>`_.
-
-   5. Copy your code directory into the repo that you cloned one your computer.
-
-   6. Add a requirements.txt file, which lets people know which external Python packages are needed to run the code in your repo. To create a file, run: ``pip freeze > requirements.txt``. Note, if you are running Anaconda, you will need to install pip first: ``conda install pip``.
-
-   7. ``git add`` all the files to the repo, which means the repo starts to track the files. Then ``git commit`` the files with a meaningful message. To learn more about this see: `Saving changes <https://www.atlassian.com/git/tutorials/saving-changes>`_. Finally, you will want to ``git push`` all your changes to GitHub, see: `Git Push <https://help.github.com/articles/pushing-to-a-remote/>`_.
-
-   8. Let people know about your package on the `MESA Wiki Page <https://github.com/projectmesa/mesa/wiki>`_ and share it on the `email list <https://groups.google.com/forum/#!forum/projectmesa>`_. In the future, we will create more of a directory, but at this point we are not there yet.

 From this point, someone can clone your repo and then add your repo to their Python path and use it in their project. However, if you want to take your package to the next level, you will want to add more structure to your package and share it on PyPI.
