 ## Usage
 
-TODO: Add usage guide.
+### In a Django Project
+
+1. Download a [release](https://github.com/platform-coop-toolkit/pinecone/releases) or `git clone` this repository.
+2. Change directories and install dependencies: `npm install`
+3. Build Pinecone: `npm run build`
+4. Copy the contents of `./build/` to your project's static directory:
+
+   `cp -r ./build/ /path/to/myproj/static/myproj/`
+
+5. Add links to the JavaScript, stylesheet, and potentially the favicon somewhere in the head element of in your template, e.g., `./templates/myproj/index.html`
+   ```
+   <script src="{% static 'myproj/scripts/pinecone.umd.js' %}"></script>
+   <link href="{% static 'myproj/styles/pinecone.css' %}" rel="stylesheet">
+   <link rel="shortcut icon" href="{% static 'myproj/images/favicon.png' %}" type="image/x-icon">
+   ```
+6. This should be enough for local development. In production, these static files should be collected, e.g.,
+
+   ```
+   python manage.py collectstatic
+   ```
