**EXAMPLE SETUP**

__STEP1:__
> Visit https://verefa.com/ and register as a developer, here you must click "New App" and copy the "token" and "tokenid"


__STEP2:__
> Install verefa as shown below.
`pip install verefa`

__STEP3:__
> Create a python client as shown below.
```
import verefa

client=verefa.machine()
client.connect(TOKENID,TOKEN,"APPNAME")
```
Ensure you substitute the values from your developer portal into the above connect statement.

__STORING DATA:__
> Begin storing data as shown below.
```
data = {
	"Name":"Marcus",
	"Email":"marcus@demomail.com"
}

response = client.send("tablename/document", data)
```
__Send Rules:__
> Data must be created as a dictionary
> The location must not begin or end with ``/``
> The paths in a send/get statement must be even.


__GETTING DATA:__
```
response = client.get("tablename/document")
```

__Get Rules:__
> Data returned will be in dictionary format.
> You can specify parameters ``client.get("tablename/document", "Name")`` This would call all documents which include the "Name" field


__EXAMPLE:__

```
import verefa

client=verefa.machine()
client.connect(123,34982,1)

print("DEMONSTRATION")

userdict = {
    "name":"Daniel",
    "email":"daniel@gmail.com"
    }

response = client.send(f"users/2", userdict)

print(response)
#prints success message

data = client.get(f"users/2")

print(data)
#prints dictionary of data previously submitted

print(data["name"])
#prints the value of field "name"

documents = client.iterate(f"users")

print(documents)
#prints a dictionary with embedded dictionaries for each user document in the table of users.


result = client.purge(f"users/mike", "FIELD", "email")
#deletes the field "email" in the document "mike"


result = client.purge(f"users/mike", "DOC")
#deletes the document "mike" and the document's data, but not the documents or directories mike held.


result = client.purge(f"users", "ALL")
#deletes the table users and all the content beneath it, does not delete content which is hidden

```

__WARNINGS:__

You can't have locations with an odd number of positions **unless using .iteration()**:
> ``client.send(f"users/bob/rewards", userdict)`` THIS IS WRONG AND WILL ERROR
> ``client.get(f"users/bob/rewards")`` THIS IS WRONG AND WILL ERROR

> ``client.send(f"users/bob/rewards/recent", userdict)`` THIS IS CORRECT AND WILL FUNCTION
> ``client.get(f"users/bob/rewards/recent")`` THIS IS CORRECT AND WILL FUNCTION

__FAQ's:__

>What is "hidden" data?

When you delete a document using ``client.purge(f"users/mike", "DOC")`` all other documents and directories under the "mike" document are not deleted, they are known as "hidden" data, and can only be manually deleted by specifically deleting each path.
