+# OpenSIPS Python Docker Image
+
+Docker recipe for running a container with pre-installed OpenSIPS Python packages.
+
+## Building the image
+You can build the docker image by running:
+```
+make build
+```
+
+This command will build a docker image with OpenSIPS Python packages installed, along with 
+`opensips-mi` and `opensips-event` command line tools.
+
+## Parameters
+
+The container receives parameters in the following format:
+```
+CMD [PARAMS]*
+```
+
+Meaning of the parameters is as it follows:
+* `CMD` - the command used to run; if the `CMD` ends with `.sh` extension, it
+will be run as a bash script, if the `CMD` ends with `.py` extension, it is
+run as a python script, otherwise it is run as a `opensips-mi` command
+* `PARAMS` - optional additional parameters passed to `CMD`
+
+## Run
+
+To run a bash script, simply pass the connector followed by the bash script:
+```
+docker run --rm opensips/python-opensips:latest script.sh
+```
+
+Similarly, run a python script:
+```
+docker run --rm opensips/python-opensips:latest script.py
+```
+
+To run a single MI command, use:
+```
+docker run --rm opensips/python-opensips:latest -t datagram uptime
+```
+
+## DockerHub
+
+Docker images are available on
+[DockerHub](https://hub.docker.com/r/opensips/python-opensips).
