+## Developing
+
+There are a few requirements when developing on `ansible-st2`:
+
+These are the platforms we must support (must pass end-to-end testing):
+- Xenial
+- Trusty
+- CentOS6
+- CentOS7
+- RHEL6 (via AWS)
+- RHEL7 (via AWS)
+
+Must also support Ansible Idempotence (Eg. Ansible-playbook re-run should end with the following results: changed=0.*failed=0)
