+## Download the latest frontend
+
+This downloads a snapshot of the latest Pleroma-FE for a given reference and writes it to the `static_dir`. In a default setup, this means that this snapshot will be served as the frontend by the backend.

+ ./bin/pleroma_ctl pleroma.frontend download [<options>]
+```
+
+```sh tab="From Source"
+mix pleroma.frontend download [<options>]
+```
+
+### Options
+- `--reference <reference>` - Specify the reference that will be downloaded. Defaults to `master`.
