+# Overview
+
+This is a simple docker file to run sigscale ocs. Nothing is tested except GUI. Use at your own risk.
+
+
+# Create Docker image using this command
+`docker build -t ocs:1.0 --build-arg ocs_ver=v3.0.4`
+
+
+# Run the docker using this command to directly attach to the erlang shell.
+`docker run -it -h ocsnode --name ocs -p8080:8080 ocs:1.0`
+or use *-d* switch to in docker run to detach and attach later to the shell
+
+# To attach to erlang shell if run as deamon with -d switch
+`docker exec -it ocs /bin/bash`
+once inside the docker container connect to the erlang node
+`erl -sname ocs1 -remsh ocs@ocsnode -setcookie ocsme`
+
+You will attach to erlang shell.
+To see if all ran successfully check with this command on erlang shell

+# Web GUI
+Browse to localhost:8080 on your machine and you should see the gui. the deafult user/pass is admin/admin
+
+# DB directory mounting. 
+If we don't want to lose the DB that is created then mount the db directory like this
+`docker run -it --name ocs -p8080:8080 -v $(pwd)/db:/opt/ocs/db ocs:1.0`
+
+# Other notes
+* The docker image disables the SSL support for HTTP and sys.config should be updated for that accordingly.
+* The diameter and radius is not tested yet. Only GUI was tried out
