+## Checkpointing Commands
+
+Checkpointing allows you to save and restore the state of your conversation and files. This is disabled by default, you must explicitly enable checkpointing using the `--checkpointing` argument or via [settings](./configuration.md).
+
+- **`/save`**
+
+  - **Description:** Saves a checkpoint of the current conversation history. You can optionally add a `[tag]` to easily identify it later.
+  - **Usage:** `/save [tag]`
+
+- **`/resume`**
+
+  - **Description:** Resumes a conversation from a previously saved checkpoint. If you don't provide a `[tag]`, it will attempt to load the latest checkpoint.
+  - **Usage:** `/resume [tag]`
+
+- **`/restore`**
+
+  - **Description:** Restores the project files to the state they were in just before a tool was executed. This is particularly useful for undoing file edits made by a tool. If run without a tool call ID, it will list available checkpoints to restore from.
+  - **Usage:** `/restore [tool_call_id]`
