+
+There are a couple of ways you can make style changes to Congo.
+
+If you just need to add or override some simple styles, you can do so by creating a `custom.css` file in your project's `static/css/` folder. This file will be loaded automatically after the theme's default styles.
+
+Alternatively, if you'd like to make a major change, you can take advantage of Tailwind CSS's JIT compiler and rebuild the entire theme CSS from scratch.

+**Note:** Building the theme manually is intended for advanced users.

+
+Change into the `themes/congo/` folder and install the project dependencies.
+
+```bash
+npm install
+```
+
+Once installed, you can edit the `themes/congo/tailwind.config.js` to change the styles that are applied throughout the theme. You can also adjust specific styles in `themes/congo/assets/css/main.css`.
+
+To allow for easy theme colour changes, Congo defines a `primary` and `secondary` colour palette that is used throughout the theme. In order to change the colour across the entire theme, simply edit the `tailwind.config.js` file accordingly.
+
+For example, to change to a green colour scheme, you could apply these changes:
+
+```js
+  // themes/congo/tailwind.config.js
+
+  theme: {
+    colors: {
+      transparent: "transparent",
+      white: colors.white,
+      gray: colors.gray,
+      primary: colors.lime,
+      secondary: colors.teal,
+    },
+    ...
+  }
+```
+
+For a full list of colours available, and their corresponding configuration values, see the official [Tailwind docs](https://tailwindcss.com/docs/customizing-colors#color-palette-reference).
+
+After editing the configuration, you need to rebuild the theme's stylesheets.
+
+```bash
+npm run build
+```
+
+This will automatically output a minified CSS file to `/themes/congo/static/css/main.css`.
+
+To aid with testing style changes, you can also run the Tailwind JIT comiler in watch mode.
+
+```bash
+npm run dev
+```
+
+Now whenever you make a change, the (non-minified) CSS files will be rebuilt automatically. This mode is useful to run when using `hugo server` to preview your site during development. Remember to perform a full build before publishing your website.
