+"gpgKeys": [

+    "KEY_ID_y"
+]
+```
+
+* It is also possible to pass multiple keys via the CLI using the repeatable `--gpg-key` flag:
+```
+aptly publish repo my-repo --gpg-key=KEY_ID_a --gpg-key=KEY_ID_b
+```
+* When using the REST API, the `gpgKey` parameter supports a comma-separated list of key IDs:
+```
+"gpgKey": "KEY_ID_a,KEY_ID_b"
+```
+* If `--gpg-key` is specified on the command line, or `gpgKey` is provided via the REST API, it takes precedence over any gpgKeys configuration in aptly.conf.
+* With multi-key support, aptly will sign all Release files (both clearsigned and detached signatures) with each provided key, ensuring a smooth key rotation process while maintaining compatibility for existing clients.
 
 #### Parameters
 
 Publish APIs use following convention to identify published repositories: `/api/publish/:prefix/:distribution`.  `:distribution` is distribution name, while `:prefix` is `[<storage>:]<prefix>` (storage is optional, it defaults to empty string), if publishing prefix contains slashes `/`, they should be replaced with underscores (`_`) and underscores
-should be replaced with double underscore (`__`). To specify root `:prefix`, use `:.`, as `.` is ambigious in URLs.
