+## Why did I create tidal-hifi?
+
+I moved from Spotify over to Tidal and found Linux support to be lacking.
+
+When I started this project there weren't any Linux apps that offered Tidal's "hifi" options nor any scripts to control it.
+
+### Why not extend existing projects?
+
+Whilst there are a handful of projects attempting to run Tidal on Electron they are all unappealing to me because of various reasons:
+
+- Lack of maintainers/developers. (no hotfixes, no issues being handled etc)
+- Most are simple web wrappers, not my cup of tea.
+- Some are DE oriented. I want this to work on WM's too.
+- None have widevine working at the moment
+
+Sometimes it's just easier to start over, cover my own needs and then making it available to the public :)

+By default tidal-hifi comes with a few themes.
+You can select these in the settings window under the theming tab as shown below.
+
+![Settings window with the theming tab opened](./images/theming.png)
+
+## Custom CSS
+
+The custom CSS will be added to the HTML document last.
+This means that it will overwrite any existing CSS, even that of themes, unless the original has an access modifier such as `$important`.
+
+![settings window on the theming tab with a custom CSS override](./images/customcss.png)
+
+## config
+
+The theme selector and customCSS are stored in the config file.
+The custom CSS is stored as a list of lines.
+
+![settings window on the theming tab next to the config file](./images/customcss-config.png)
+
+## Warning! Themes might break
+
+Themes might break at any point. Tidal changes their webpage structure a ton (they probably generate classNames and don't provide roles/ids/attributes.)
+
+If one breaks you can create an Issue on GitHub or ask for assistance in the [Discord channel](https://discord.gg/yhNwf4v4He).
