+# Setup Theme
+As of Gitea version **1.17.0**, create directories in your Gitea custom file path with this name: **/assets/css/**. You can find your custom Gitea file path by navigating to **Site Administration -> Config** and looking under **Custom File Root Path**.
+
+Take both *theme-nico.css* and *nicofooter.png* and insert them in this folder.
+
+## Enable Theme
+Go to your **app.ini Configuration File** (again, look under the Config page for what this is) and open the **app.ini**. If your file does not have a **[ui]** heading, add the following somewhere in the file:
+```bash
+[ui]
+DEFAULT_THEME = auto
+THEMES = auto,gitea,arc-green,nico
+```
+By adding **nico** to the end of the list you can now select it when you go to your *Appearance* options list. If you want the nico theme to be the default theme, then change **auto** to **nico**
+
+If the **THEMES** key is already present somewhere in your app.ini file, simply add nico to the list
