You can think of `APIRouter` as a "mini `FastAPI`" class.

All the same options are supported.

All the same `parameters`, `responses`, `dependencies`, `tags`, etc.

/// tip

In this example, the variable is called `router`, but you can name it however you want.

## Create a Virtual Environment { #create-a-virtual-environment }

When you start working on a Python project **for the first time**, create a virtual environment **<abbr title="there are other options, this is a simple guideline">inside your project</abbr>**.

/// tip

You only need to do this **once per project**, not every time you work.
