-This is an example of a Python Worker that uses a built-in package (FastAPI) with a vendored package (Jinja2).
+This is an example of a Python Worker that uses the FastMCP package.
 
 ## Adding Packages
 
-Built-in packages can be selected from [this list](https://developers.cloudflare.com/workers/languages/python/packages/#supported-packages) and added to your `requirements.txt` file. These can be used with no other explicit install step.
-
 Vendored packages are added to your source files and need to be installed in a special manner. The Python Workers team plans to make this process automatic in the future, but for now, manual steps need to be taken.
 
 ### Vendoring Packages
 
-[//]: # (NOTE: when updating the instructions below, be sure to also update the vendoring.yml CI workflow)
-
 First, install Python3.12 and pip for Python 3.12.
 
 *Currently, other versions of Python will not work - use 3.12!*

-### Using Vendored packages
-
-In your wrangler.toml, make the vendor directory available:
-
-```toml
-[[rules]]
-globs = ["vendor/**"]
-type = "Data"
-fallthrough = true
-```
-
-Now, you can import and use the packages:
-
-```python
-import jinja2
-# ... etc ...
-```
-
 ### Developing and Deploying
 
 To develop your Worker, run `npx wrangler@latest dev`.
