-# Plugins with `plugin@<name>.ts`
+# Qwik Plugins
+Qwik plugins, named as `plugin.ts` or `plugin@<name>.ts`, handle incoming requests prior to root layout execution and are located in the `src/routes` directory. Request handlers like `onRequest`, `onGet`, `onPost` in these plugins are called before `server$` functions. For multiple plugins, `plugin.ts` handlers execute first, followed by `plugin@<name>.ts` handlers in alphabetical order. Middleware functions should be defined in `plugin.ts` to ensure execution for all requests.

+# `plugin@<name>.ts`
 
 `plugin.ts` and `plugin@<name>.ts` files can be created in the root of the `src/routes` directory to handle any incoming request before even the root layout executes.
