### Step 3: Activate
Select the `darkside-master` folder and press `Open`. N1 will make a copy of the theme files into your `.nylas/packages` directory, notify you that the theme has been installed, and open it a new Finder window.
If you need to get back to the package files, they're located at `/Users/<yourUsername>/.nylas/packages/darkside-master`. Either use Terminal or you can open a Finder window and press <kbd>Cmd</kbd> + <kbd>Shift</kbd> + <kbd>G</kbd> and paste the path in, replacing `<yourUsername>` with your username.
### Step 3: Customize
To customize Darkside, open `darkside-master/styles/darkside.less` in a text editor.
**To change colors, just comment out the default `@sidebar` and `@accent` variables and uncomment another theme or simply replace with your own colors.**
```sass
// Default
@sidebar:#313042;
@accent:#F18260;
// Luna
// @sidebar:#202C46;
// @accent:#39DFF8;
// Zond
// @sidebar:#333333;
