+# Static Assets for Chirpy Jekyll Theme
+
+## Introduction
+
+Static assets (libraries/plugins/web-fonts) required by the [_Chirpy_][chirpy] based website to run. It provides the opportunity to choose self-host assets in production or development mode.
+
+## Usage
+
+- If you want to use these assets only in local development:
+
+  Go to the root of your site and clone the assets as follows.
+
+  ```console
+  $ cd assets/lib
+  $ git submodule init
+  $ git submodule update
+  ```
+
+  And then set your site configuration options:
+
+  ```yml
+  # _config.yml
+  assets:
+    self_host:
+      enabled: true
+      env: development
+  ```
+
+- If you expect the assets to be self-hosted when your website is published:
+
+  Keep the `_config.yml` options as follows:
+
+  ```yml
+  # _config.yml
+  assets:
+    self_host:
+      enabled: true
+  ```
+
+  And then update the GitHub Actions workflow in `.github/workflows/pages-deploy.yml`:
+
+  ```diff
+  steps:
+    - name: Checkout
+      uses: actions/checkout@v2
+      with:
+  +     submodules: true
+  ```
