+**Concurrency in Python**
+
+Python provides the ability to run multiple tasks and coroutines simultaneously with the use of the `asyncio` library, which is included in the Python standard library.
+
+This works by running these coroutines in an event loop, where the context of which coroutine is being run is switches periodically to allow all of them to run, giving the appearance of running at the same time. This is different to using threads or processes in that all code is run in the main process and thread, although it is possible to run coroutines in threads.
+
+To call an async function we can either `await` it, or run it in an event loop which we get from `asyncio`.
+
+To create a coroutine that can be used with asyncio we need to define a function using the async keyword:
+```py
+async def main():
+    await something_awaitable()
+```
+Which means we can call `await something_awaitable()` directly from within the function. If this were a non-async function this would have raised an exception like: `SyntaxError: 'await' outside async function`
+
+To run the top level async function from outside of the event loop we can get an event loop from `asyncio`, and then use that loop to run the function:
+```py
+from asyncio import get_event_loop
+
+async def main():
+    await something_awaitable()
+
+loop = get_event_loop()
+loop.run_until_complete(main())
+```
+Note that in the `run_until_complete()` where we appear to be calling `main()`, this does not execute the code in `main`, rather it returns a `coroutine` object which is then handled and run by the event loop via `run_until_complete()`.
+
+To learn more about asyncio and its use, see the [asyncio documentation](https://docs.python.org/3/library/asyncio.html).

+**Why do we need asynchronous programming?**
+
+Imagine that you're coding a Discord bot and every time somebody uses a command, you need to get some information from a database. But there's a catch: the database servers are acting up today and take a whole 10 seconds to respond. If you do **not** use asynchronous methods, your whole bot will stop running until it gets a response from the database. How do you fix this? Asynchronous programming.
+
+**What is asynchronous programming?**
+
+An asynchronous program utilises the `async` and `await` keywords. An asynchronous program pauses what it's doing and does something else whilst it waits for some third-party service to complete whatever it's supposed to do. Any code within an `async` context manager or function marked with the `await` keyword indicates to Python, that whilst this operation is being completed, it can do something else. For example:
+
+```py
+import discord
+
+# Bunch of bot code
+
+async def ping(ctx):
+    await ctx.send("Pong!")
+```
+
+**What does the term "blocking" mean?**
+
+A blocking operation is wherever you do something without `await`ing it. This tells Python that this step must be completed before it can do anything else. Common examples of blocking operations, as simple as they may seem, include: outputting text, adding two numbers and appending an item onto a list. Most common Python libraries have an asynchronous version available to use in asynchronous contexts.
+
+**`async` libraries**
+
+The standard async library - `asyncio`
+Asynchronous web requests - `aiohttp`
+Talking to PostgreSQL asynchronously - `asyncpg`
+MongoDB interactions asynchronously - `motor`
+Check out [this](https://github.com/timofurrer/awesome-asyncio) list for even more!

+**Custom Command Checks in discord.py**
+
+Often you may find the need to use checks that don't exist by default in discord.py. Fortunately, discord.py provides `discord.ext.commands.check` which allows you to create you own checks like this:
+```py
+from discord.ext.commands import check, Context
+
+def in_any_channel(*channels):
+  async def predicate(ctx: Context):
+    return ctx.channel.id in channels
+  return check(predicate)
+```
+This check is to check whether the invoked command is in a given set of channels. The inner function, named `predicate` here, is used to perform the actual check on the command, and check logic should go in this function. It must be an async function, and always provides a single `commands.Context` argument which you can use to create check logic. This check function should return a boolean value indicating whether the check passed (return `True`) or failed (return `False`).
+
+The check can now be used like any other commands check as a decorator of a command, such as this:
+```py
[email protected](name="ping")
+@in_any_channel(728343273562701984)
+async def ping(ctx: Context):
+  ...
+```
+This would lock the `ping` command to only be used in the channel `728343273562701984`. If this check function fails it will raise a `CheckFailure` exception, which can be handled in your error handler.

+A [`docstring`](https://docs.python.org/3/glossary.html#term-docstring) is a string - always using triple quotes - that's placed at the top of files, classes and functions. A docstring should contain a clear explanation of what it's describing. You can also include descriptions of the subject's parameter(s) and what it returns, as shown below:
+```py
+def greet(name: str, age: int) -> str:
+    """

+```
+You can get the docstring by using the [`inspect.getdoc`](https://docs.python.org/3/library/inspect.html#inspect.getdoc) function, from the built-in [`inspect`](https://docs.python.org/3/library/inspect.html) module, or by accessing the `.__doc__` attribute. `inspect.getdoc` is often preferred, as it clears indents from the docstring.
+
+For the last example, you can print it by doing this: `print(inspect.getdoc(greet))`.

+**Using .env files in Python**
+
+`.env` (dotenv) files are a type of file commonly used for storing application secrets and variables, for example API tokens and URLs, although they may also be used for storing other configurable values. While they are commonly used for storing secrets, at a high level their purpose is to load environment variables into a program.
+
+Dotenv files are especially suited for storing secrets as they are a key-value store in a file, which can be easily loaded in most programming languages and ignored by version control systems like Git with a single entry in a `.gitignore` file.
+
+In python you can use dotenv files with the [`python-dotenv`](https://pypi.org/project/python-dotenv) module from PyPI, which can be installed with `pip install python-dotenv`. To use dotenv files you'll first need a file called `.env`, with content such as the following:
+```
+TOKEN=a00418c85bff087b49f23923efe40aa5
+```
+Next, in your main Python file, you need to load the environment variables from the dotenv file you just created:
+```py
+from dotenv import load_dotenv()
+
+load_dotenv(".env")
+```
+The variables from the file have now been loaded into your programs environment, and you can access them using `os.getenv()` anywhere in your program, like this:
+```py
+from os import getenv
+
+my_token = getenv("TOKEN")
+```
+For further reading about tokens and secrets, please read [this explanation](https://vcokltfre.dev/tips/tokens).

+**Dunder methods**
+
+Double-underscore methods, or "dunder" methods, are special methods defined in a class that are invoked implicitly. Like the name suggests, they are prefixed and suffixed with dunders. You've probably already seen some, such as the `__init__` dunder method, also known as the "constructor" of a class, which is implicitly invoked when you instantiate an instance of a class.
+
+When you create a new class, there will be default dunder methods inherited from the `object` class. However, we can override them by redefining these methods within the new class. For example, the default `__init__` method from `object` doesn't take any arguments, so we almost always override that to fit our needs.
+
+Other common dunder methods to override are `__str__` and `__repr__`. `__repr__` is the developer-friendly string representation of an object - usually the syntax to recreate it - and is implicitly called on arguments passed into the `repr` function. `__str__` is the user-friendly string representation of an object, and is called by the `str` function. Note here that, if not overriden, the default `__str__` invokes `__repr__` as a fallback.
+
+```py
+class Foo:
+    def __init__(self, value):  # constructor
+        self.value = value
+    def __str__(self):
+        return f"This is a Foo object, with a value of {self.value}!"  # string representation
+    def __repr__(self):
+        return f"Foo({self.value!r})"  # way to recreate this object
+
+
+bar = Foo(5)
+
+# print also implicitly calls __str__
+print(bar)  # Output: This is a Foo object, with a value of 5!
+
+# dev-friendly representation
+print(repr(bar))  # Output: Foo(5)
+```
+
+Another example: did you know that when you use the `<left operand> + <right operand>` syntax, you're implicitly calling `<left operand>.__add__(<right operand>)`? The same applies to other operators, and you can look at the [`operator` built-in module documentation](https://docs.python.org/3/library/operator.html) for more information!

+**for-else**
+
+In Python it's possible to attach an `else` clause to a for loop. The code under the `else` block will be run when the iterable is exhausted (there are no more items to iterate over). Code within the else block will **not** run if the loop is broken out using `break`.
+
+Here's an example of its usage:

 • Makes import order significant, which they shouldn't. Certain IDE's `sort import` functionality may end up breaking code due to namespace collision.

+If you want a coverage report, make sure to run the tests with `poetry run task test` *first*.
+
+## Running tests
+There are multiple ways to run the tests, which one you use will be determined by your goal, and stage in development.
+
+When actively developing, you'll most likely be working on one portion of the codebase, and as a result, won't need to run the entire test suite.
+To run just one file, and save time, you can use the following command:
+```shell
+poetry run task test-nocov <path/to/file.py>
+```
 
-If you want a coverage report, make sure to run the tests with `pipenv run test` *first*.
+For example:
+```shell
+poetry run task test-nocov tests/bot/exts/test_cogs.py
+```
+will run the test suite in the `test_cogs` file.
+
+If you'd like to collect coverage as well, you can append `--cov` to the command above.
+
+
+If you're done and are preparing to commit and push your code, it's a good idea to run the entire test suite as a sanity check:
+```shell
+poetry run task test
+```

 ### Mocking coroutines
 
-By default, the `unittest.mock.Mock` and `unittest.mock.MagicMock` classes cannot mock coroutines, since the `__call__` method they provide is synchronous. In anticipation of the `AsyncMock` that will be [introduced in Python 3.8](https://docs.python.org/3.9/whatsnew/3.8.html#unittest), we have added an `AsyncMock` helper to [`helpers.py`](/tests/helpers.py). Do note that this drop-in replacement only implements an asynchronous `__call__` method, not the additional assertions that will come with the new `AsyncMock` type in Python 3.8.
