 ### Chat in Bash
 
 We can chat straight from the command line.
 For example, via the DeepInfra API:
 
 ```sh
-$ DEEPINFRA_KEY="$(cat /path/to/key)"; echo "hi there" | ata chat
+$ DEEPINFRA_KEY="<KEY>"; echo "hi there" | ata chat
 ```
 
 This defaults to the `meta-llama/Llama-3.3-70B-Instruct` model.
