-This service currently ships the default adminer package with no _external_ plugins. It contains all official plugins and themes and allows to easily chose one by editing the `docker-compose.adminer.yaml` file after installation.
+The official container supports:
+
+* MySQL / MariaDB
+* PostgreSQL
+* SQLite
+* SimpleDB
+* Elasticsearch
+
+## Why?
+
+Because you might need something other than MySQL / MariaDB in your DDEV project. We got you covered.
 
 ## Installation
 
 * `ddev get bserem/ddev-adminer && ddev restart`
 
 ## Caveats
-* You need to pass database credentials manually for the time being. If you have any ideas on how to overcome this issue please let me know. **Default ddev database credentials are: user `db`, pass `db`, database `db`.**
