 ## Usage
 After installing the extensions, selecting text and pressing `Ctrl+Space` will display the answer above the selected text in the configured opacity. To hide the answer, press `Ctrl+Space` again without selecting any text.
+
 Additionally, pressing `Ctrl+Shift+Space` will write the answer into the nearest text field.
 
 ## Configuration
 The extension can be configured by clicking on the extension icon in the toolbar.
+
 You will need to add your own OpenAI Endpoint (for example `https://api.elia.network`), and an API key.
+
 There is an default URL and Key which is restricted to llama3.2-90b and 10 Requests per minute.
+
 The opacity can be adjusted from 0 to 1, and is set to 0.1 per default. Adjust based on your screen's brightness and if you want to risk it being spotted.
 
 ## Installation
+Download the latest release from the [releases page](https://git.elia.network/elia/cas/releases) and open it with Firefox. It should prompt you to install the extension.
