 **Custom Command Checks in discord.py**
 
-You may find yourself in need of a check decorator to do something that doesn't exist in discord.py by default, but fear not, you can make your own! Using discord.py you can use `discord.ext.commands.check` to create you own checks like this:

-There's a fair bit to break down here, so let's start with what we're trying to achieve with this check. As you can probably guess from the name it's locking a command to a **list of channels**. The inner function named `predicate` is used to perform the actual check on the command context. Here you can do anything that requires a `Context` object. This inner function should return `True` if the check is **successful** or `False` if the check **fails**.
+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`).
 
-Here's how we might use our new check:
+The check can now be used like any other commands check as a decorator of a command, such as this:
 ```py
 @bot.command(name="ping")
 @in_any_channel(728343273562701984)
