+### Docker
+
+A Dockerfile is included to build and run your own OCI images. To build:
+
+```
+$ docker build [--build-arg PUID=1000] [--build-arg PGID=1000] -t scribe:latest -f ./Dockerfile .
+```
+
+To run (generating a base config from environment variables):
+
+```
+$ docker run -it --rm -p 8080:8080 -e SCRIBE_PORT=8080 -e SCRIBE_HOST=0.0.0.0 -e SCRIBE_DB=postgres://does@not/matter scribe:latest
+```
+
+To run with mounted config from local fs:
+
+```
+$ docker run -it --rm -v `pwd`/config/watch.yml:/app/config/watch.yml -p 8080:8080 scribe:latest
+```
+
