+# Docker
+
+## Docker Hub
+
+An official container image available at https://hub.docker.com/r/hufrea/byedpi.
+
+Images are tagged by full version number (`major.minor.patch`) and `major.minor`. As usual the latest stable release has `latest` tag.
+
+## Building
+
+To build a container image from the source execute:
+
+```sh
+docker build . --tag my/byedpi
+```
+
+A tag allows to reference built image by human-readable name instead of hash and is optional.
+
+Provided `Dockerfile` is compatible with podman if you want an alternative to docker.
+
+## Running
+
+To run a byedpi container use the command:
+
+```sh
+docker run -it --rm hufrea/byedpi --help
+```
+
+Don't forget to expose a port to communicate with the container. For example to have local only access to byedpi SOCKS proxy on port 1234 add `-p 127.0.0.1:1234:1080` before the image name:
+
+```sh
+docker run -it --rm -p 127.0.0.1:1234:1080 hufrea/byedpi --fake -1 --md5sig
+```
+
+## Compose
+
+Docker compose is useful to simplify management of docker containers.
+
+To use provided `compose.yaml` edit
+1) arguments passed to byedpi in `command` array
+2) `published` port if 1080 is already allocated
+and run the command inside a directory containing `compose.yaml`
+
+```sh
+docker compose up -d
+```
+
+If docker daemon configured to start on system boot, it will keep byedpi container always up.
