+# Taskwarrior Server (taskd) Docker
+
+(c) 2015 Óscar García Amor
+Redistribution, modifications and pull requests are welcomed under the terms
+of MIT license.
+
+[Taskwarrior](https://www.taskwarrior.org) is Free and Open Source Software
+that manages your TODO list from your command line. It is flexible, fast,
+efficient, and unobtrusive. It does its job then gets out of your way.
+
+This docker packages **taskd**, Taskwarrior sync server, under [Alpine
+Linux](https://alpinelinux.org/), a lightweight Linux distribution.
+
+## Run
+
+To run this container exposing taskd default port and making the data volume
+permanent in `/srv/taskd`, simply run.
+
+```sh
+docker run -d \
+  --name=taskd \
+  -p 53589:53589 \
+  -v /srv/taskd:/var/taskd \
+  ogarcia/taskd
+```
+
+This makes a set of self signed certificates and minimal configuration to
+run server.
+
+## Manual setup
+
+The `run.sh` script that launch **taskd** server always look for config file
+in data volume `/var/taskd`. If found it, simply run the server, but if
+config file is absent `run.sh` will build a new default config and its
+certificates.
+
+If you make the data volume permanent you'll can access to its contents and
+make modifications that you need. The significant files are.
+
+* `config` taskd config itself.
+* `log` directory of log.
+* `org` taskd data.
+* `pki` directory that contains certs and certs generation helpers.
+
+You can do any changes to this, but remember that if you delete `config`
+file, the `run.sh` script will rebuild everything.
+
+Please refer to [Taskwarrior Docs](https://taskwarrior.org/docs/) to know
+how do modifications, add users, etc.
+
+## Shell run
+
+In some cases, you could need to run `taskd` command. You can run this
+docker in interactive mode, simply do.
+
+```sh
+docker run -ti --rm \
+  -v /srv/taskd:/var/taskd \
+  ogarcia/taskd /bin/sh
+```
+
+This mounts the permanent data volume `/srv/taskd` into **taskd** data
+directory and gives you a interactive shell to work.
+
+Please note that the `--rm` modifier destroy the docker after shell exit.
