+== Quickly launch Redmine trial environment with Docker
+
+You can use Docker to quickly set up a Redmine environment for a trial. 
+
+1. Uncompress the program archive
+
+2. Build a Docker image by running:
+     docker build -t redmine_trial .
+
+3. Launch Redmine in a new Docker container by running:
+     docker run -it -p 3000:3000 -e RAILS_ENV=production redmine_trial
+
+   Once Redmine has started, point your browser to http://localhost:3000/
+   You should now see the application welcome page.
+
+4. Delete the container and image after have played with Redmine:
+     docker container rm CONTAINER_ID
+     docker image rm redmine_trial
+
