+description: How to use PostCSS in your Snowpack project.
+---
+
+[PostCSS](https://postcss.org/) is a popular CSS transpiler with support for [a huge ecosystem of plugins.](https://github.com/postcss/postcss#plugins)
+
+**To use PostCSS with Snowpack:** add the [@snowpack/plugin-postcss](https://www.npmjs.com/package/@snowpack/plugin-postcss) plugin to your project.
+
+```diff
+// snowpack.config.js
+"plugins": [
++  "@snowpack/plugin-postcss"
+]
+```
+
+PostCSS requires a [`postcss.config.js`](https://github.com/postcss/postcss#usage) file in your project. By default, the plugin looks in the root directory of your project, but you can customize this yourself with the `config` option. See [the plugin README](https://www.npmjs.com/package/@snowpack/plugin-postcss) for all available options.
+
+```js
+// postcss.config.js
+// Example (empty) postcss config file
+module.exports = {
+  plugins: [
+    // ...
+  ],
+};
+```
+
+Be aware that this plugin will run on all CSS in your project, including any files that compiled to CSS (like `.scss` Sass files, for example).
