+With this repo you can easily run your own instance of the opentracker for bitorrent.
+
+## How to use it
+If you want to run a complety open tracker, just pull the docker image and spin up a container:
+
+`docker run -d --name opentracker -p 6969:6969/udp -p 6969:6969 lednerb/opentracker-docker`
+
+This will bind the port `6969` to the docker container (UDP and TCP) and you're good to go.
+
+
+If you want to config your opentracker instance, just download or pull the github repository and edit the `opentracker.conf` file.
+
+Than you have to build your own image as follows:
+ 1. Edit and save the `opentracker.conf` file
+ 2. Open a terminal and `cd` into the project folder
+ 3. Run `docker build -t yourfancyname/opentracker .`
+
+After the docker image was successfully build you can start a container:
+
+`docker run -d --name opentracker -p 6969:6969/udp -p 6969:6969 lednerb/opentracker-docker`
