+### `depot cache`
+
+Interact with the cache associated with a Depot project. The `cache` command consists of subcommands for each operation.
+
+#### `depot cache reset`
+
+Reset the cache of the Depot project to force a new empty cache volume to be created.
+
+**Example**
+
+Reset the cache of the current project ID in the root `depot.json`
+
+```
+depot cache reset .
+```
+
+Reset the cache of a specific project ID
+
+```
+depot cache reset --project 12345678910
+```
+
 ### `depot init`
 
 Initialize an existing Depot project in the current directory. The CLI will display an interactive list of your Depot projects for you to choose from, then write a `depot.json` file in the current directory with the contents `{"projectID": "xxxxxxxxxx"}`.
