+### `Ask`
+
+The ask command allows you to ask the Pieces Copilot a question. By default, it uses the GPT-3.5 model, but you can change the model using the `list models` command. You can also add relevant files and snippets to provide more context for your question. 
+The question that is asked, will generate a new conversation. To change the current conversation use the `conversation` command
+
+```shell
+pieces ask "your question" -f /file1 /file2 folder -s 1 2 3
+```
+
+- **"your question":** The question you want to ask the Pieces Copilot. It must be enclosed in quotes.
