+# Simple Development Sandbox
+
+Follow these steps to build and run a simple deployment of COmanage Registry
+suitable for beginning COmanage Registry development.
+
+* Complete all of the steps in 
+[Evaluating COmanage Registry using Docker](evaluation.md). Make sure you can
+log into COmanage Registry but do not save any changes. Be sure to run
+`docker compose down` so that no containers are left running.
+
+* Create a directory somewhere to save the state of the COmanage Registry
+database. For example
+
+```
+sudo mkdir -p /srv/docker/var/lib/postgresql/data
+```
+
+* Clone the COmanage Registry repository somewhere, for example
+
+```
+cd $HOME
+git clone https://github.com/Internet2/comanage-registry.git
+```
+
+* Change directories into the repository you just
+cloned and create some necessary files and set appropriate permissions:
+
+```
+cd comanage-registry
+cp -a app/tmp.dist local/tmp
+chmod -R o+rw local/tmp
+```
+
+* Tell git to ignore changes the container makes during startup:
+
+```
+git update-index --assume-unchanged app/Config/bootstrap.php
+```
+
+* Checkout the develop branch or any other branch you want to work
+from (you probably do not want to work from master):
+
+```
+git checkout develop
+```
+
+* Edit the docker-compose.yml file you used previously and add three
+volume bind mounts:
+
+  1. One volume will mount the directory you created in the above
+     step for saving the database state to the directory
+     `/var/lib/postgresql/data` inside the database container.
+  1. A second volume will mount the `app` directory from the COmanage
+     Registry repository clone you created to the
+     `/srv/comanage-registry/app` directory inside the 
+     COmanage Registry container.
+  1. The third volume will mount the `local` directory from the
+     COmanage Registry repository clone to the
+     `/srv/comanage-registry/local` directory inside the COmanage
+     Registry container.
+
+Below is an example. The details will depend where you create the
+database state directory and the repository clone. Be sure to
+adjust the volume mounts for your deployment.
+
+```
+version: '3.1'
+
+services:
+
+    comanage-registry-database:
+        image: comanage-registry-postgres
+        volumes:
+            - /srv/docker/var/lib/postgresql/data:/var/lib/postgresql/data
+
+    comanage-registry:
+        image: "comanage-registry:${COMANAGE_REGISTRY_VERSION}-basic-auth"
+        volumes:
+            - /home/skoranda/comanage-registry/app:/srv/comanage-registry/app
+            - /home/skoranda/comanage-registry/local:/srv/comanage-registry/local
+
+        ports:
+            - "80:80"
+            - "443:443"
+```
+
+* Make sure the shell variable `COMANAGE_REGISTRY_VERSION` is still
+set (see [Evaluating COmanage Registry using Docker](evaluation.md).)
+
+* Start the services:
+```
+docker-compose up -d
+```
+
+* Browse to port 443 on the host, for example `https://localhost/`. You will have to
+  click through the warning from your browser about the self-signed certificate used
+  for HTTPS.
+
+* Click `Login` and when prompted enter `registry.admin` as the username and `password`
+for the password. 
+
+* Visit the [COmanage Developer Manual](https://spaces.at.internet2.edu/x/FYDVCQ) for
+tips and suggestions as well as the [COmanage Coding Style](https://spaces.at.internet2.edu/x/l6_KAQ).
+
+* To stop the services:
+```
+docker-compose stop
+```
+
+* To remove the containers and networks:
+```
+docker-compose down
+```
+
+### Important Notes
+The instructions above are *not suitable for a production deployment* 
+since the deployed services use default and easily guessed passwords.
