+## Docker
+
+To build a docker image with the latest version of ZNC, run:
+
+```shell
+docker build -t $(USER)/znc:latest .
+```
+
+This includes Perl and Python support. Then start ZNC:
+
+```shell
+docker run -i -t -v $HOME/.znc:/home/znc/data -p 6667:6667 $(USER)/znc:latest
+```
+
+If you haven't set up a configuration yet, you need to pass `--makeconf`:
+
+```shell
+docker run -i -t -v $HOME/.znc:/home/znc/data -p 6667:6667 $(USER)/znc:latest --makeconf
+```
+
+Then rerun without `--makeconf`, and if everything looks good, start ZNC in the background:
+
+```shell
+docker run -d -v $HOME/.znc:/home/znc/data -p 6667:6667 --name znc $(USER)/znc:latest
+```
+
+You can verify that everything is running smoothly by running:
+
+```shell
+docker ps && docker logs znc
+```
+
+To build extra modules, place the source files in `~/.znc/modules` like usual, and then run:
+
+```shell
+docker exec -u root znc apk add --no-cache build-base cmake openssl-dev icu-dev
+docker exec -u root znc sh -c 'cd $HOME/modules && znc-buildmod *.cpp'
+```
+
+Since the module's `.so` file is placed in the exported volume, you don't need to
+commit these changes in the container back to the image.
+
+To restart the container, simply run:
+
+```shell
+docker restart znc
+```
+
+At any time, you can remove the znc container, and recreate it by running:
+
+```shell
+docker rm znc
+docker create -v $HOME/.znc:/home/znc/data -p 6667:6667 --name znc $(USER)/znc:latest
+```
+
+The docker image can be customized via build arguments, eg. for a development build:
+
+```shell
+docker build -t $(USER)/znc:latest --build-arg config_flags="--enable-perl --enable-python 3.5 --enable-debug" --build-arg cleanup_cmds="" --build-arg make_flags="-j8" .
+```
+
+And then built in place, if the host source directory is mounted using `-v /host/src:/home/znc/src`:
+
+```shell
+docker exec --user root znc make install -C /home/znc/build && docker restart znc && docker logs znc
+```
+
