 You can add Qt themes to Grabber, using [CSS](https://en.wikipedia.org/wiki/CSS) to customize all parts of the UI.
 
-To add a new theme to Grabber, just create a folder in the `themes` directory (located in `C:/Users/%USERNAME%/AppData/Local/Bionus/Grabber` on Windows) with the name of your theme. Then create a `style.css` file inside that new folder. You just have to write your CSS into that file!

 ## Based on an existing source type
 
+If the site you're trying to add uses the same source type (e.g. Gelbooru 0.1) as already-supported sites, you're in luck as it should be easy to add it to Grabber.
+
 1. Start the program.
 2. Click on the "Sources" button at the bottom of a search tab
 3. Click on the "Add" button at the bottom of the window that just popped up
 4. Fill the Url field, and leave the "Guess" checkbox checked
-5. If an error occurs, uncheck "Guess", and choose a source type manually in the list

-    If Shimmie-based boards are currently supported, a lot of them are still buggy, so beware when using them
+5. If the program fails to guess the source type, uncheck "Guess", and choose a source type manually in the list
 
 
 ## Create a new source type
 
 If none of the available sources types match the website you want to add, you'll have to create one yourself.

 * The `name` field is quite obvious, we just use "JSON" because that's the format used by this API
 * The `auth` field is left as an empty array, because even anonymous users can use this API, no authentication is required
 * The `search` object contains two functions, `url()` and `parse()` that we will now discuss in more detail
