+A config extension to Server to deliver drone files for repositories where you can't put a drone file in. _Please note this project requires Drone server version 1.4 or higher._
+
+## Installation
+
+Create a shared secret:
+
+```console
+$ openssl rand -hex 16
+bea26a2221fd8090ea38720fc445eca6
+```
+
+Download and run the extension:
+
+```console
+$ docker run -d \
+  --publish=3000:3000 \
+  --env=DRONE_DEBUG=true \
+  --env=DRONE_SECRET=bea26a2221fd8090ea38720fc445eca6 \
+  --restart=always \
+  --name=config garionion/drone-yaml-server
+```
+
+Update your Drone server configuration to include the extension address and the shared secret.
+
+```text
+DRONE_YAML_ENDPOINT=http://1.2.3.4:3000
+DRONE_YAML_SECRET=bea26a2221fd8090ea38720fc445eca6
+```
+
+## Testing
+
+Use the command line tools to test your extension. _This extension uses http-signatures to authorize client access and will reject unverified requests. You will be unable to test this extension using a simple curl command._
+
+```text
+export DRONE_YAML_ENDPOINT=http://1.2.3.4:3000
+export DRONE_YAML_SECRET=bea26a2221fd8090ea38720fc445eca6
+
+drone plugins config get <repo>
+```
