-Tailwind uses the [Jigsaw](http://jigsaw.tighten.co/) static site generator for its documentation. Here is how you can generate the documentation locally:
-
-1. Go to your Tailwind folder
-
-    ```sh
-    cd tailwindcss
-    ```
-
-2. Install JS dependencies
-
-    ```sh
-    npm install
-    ```
-
-3. Transpile the source code
-
-    ```sh
-    npm run prepare
-    ```
-
-4. Go to docs folder
-
-    ```sh
-    cd docs
-    ```
-
-5. Install PHP dependencies for docs (requires Composer: https://getcomposer.org)
-
-    ```sh
-    composer install
-    ```
-
-6. Install JS dependencies for docs
-
-    ```sh
-    npm install
-    ```
-
-7. Run the build to generate the static site
-
-    ```sh
-    npm run dev
-    ```
-
-8. View the static site at `/tailwind/docs/build_local`, or you can run the Jigsaw server:
-
