## Instructions for installing and uninstalling `embeam`



### Installing `embeam`

For all installation scenarios, first open up the appropriate command line
interface. On Unix-based systems, you could open e.g. a terminal. On Windows
systems you could open e.g. an Anaconda Prompt as an administrator.



#### Installing `embeam` using `pip`

Before installing `embeam`, make sure that you have activated the (virtual)
environment in which you intend to install said package. After which, simply run
the following command:

    pip install embeam

The above command will install the latest stable version of `embeam`.

To install the latest development version from the main branch of the [embeam
GitHub repository](https://github.com/mrfitzpa/embeam), one must first clone the
repository by running the following command:

    git clone https://github.com/mrfitzpa/embeam.git

Next, change into the root of the cloned repository, and then run the following
command:

    pip install .

Note that you must include the period as well. The above command executes a
standard installation of `embeam`.

Optionally, for additional features in `embeam`, one can install additional
dependencies upon installing `embeam`. To install a subset of additional
dependencies (along with the standard installation), run the following command
from the root of the repository:

    pip install .[<selector>]

where `<selector>` can be one of the following:

* `tests`: to install the dependencies necessary for running unit tests;
* `examples`: to install the dependencies necessary for executing files stored
  in `<root>/examples`, where `<root>` is the root of the repository;
* `docs`: to install the dependencies necessary for documentation generation;
* `all`: to install all of the above optional dependencies.

Alternatively, one can run:

    pip install embeam[<selector>]

elsewhere in order to install the latest stable version of `embeam`, along with
the subset of additional dependencies specified by `<selector>`.



#### Installing `embeam` using `conda`

To install `embeam` using the `conda` package manager, run the following
command:

    conda install -c conda-forge embeam

The above command will install the latest stable version of `embeam`.



### Uninstalling `embeam`

If `embeam` was installed using `pip`, then to uninstall, run the following
command:

    pip uninstall embeam

If `embeam` was installed using `conda`, then to uninstall, run the following
command:

    conda remove embeam



## Learning how to use `embeam`

For those new to the `embeam` library, it is recommended that they take a look
at the [Examples](https://mrfitzpa.github.io/embeam/examples.html) page, which
contain code examples that show how one can use the `embeam` library. While
going through the examples, readers can consult the [embeam reference
guide](https://mrfitzpa.github.io/embeam/_autosummary/embeam.html) to understand
what each line of code is doing.
