 # zsh-copilot
 
-How we all expected GitHub Copilot in the CLI to be.
+Get suggestions **truly** in your shell. No `suggest` bullshit. Just press `CTRL + Z` and get your suggestion.
 
 ## Installation
 
+### Dependencies
+
+Please make sure you have the following dependencies installed:
+
+* [zsh-autosuggestions](https://github.com/zsh-users/zsh-autosuggestions)
+
 ```sh
 git clone https://github.com/Myzel394/zsh-copilot.git ~/.zsh-copilot
 echo "source ~/.zsh-copilot/zsh-copilot.plugin.zsh" >> ~/.zshrc
 ```
 
+### Configuration
+
+You need to have an OPENAI API key with access to `gpt-4` to use this plugin. Expose this via the `OPENAI_API_KEY` environment variable:
+
+```sh
+export OPENAI_API_KEY=<your-api-key>
+```
+
+I tried out using `gpt-3` but the results were garbage.
+
 ## Usage
 
 Type in your command or your message and press `CTRL + Z` to get your suggestion!
