-## What is this?
+## Overview
 
-This repository allows you to quickly install the [Adminer](https://www.adminer.org/) database manager into a [DDEV](https://ddev.readthedocs.io) project using just `ddev add-on get ddev/ddev-adminer`.
+[Adminer](https://www.adminer.org/) is a full-featured database management tool written in PHP.
 
-Adminer is a full-featured database management tool written in PHP. This service currently ships the [official adminer container](https://hub.docker.com/_/adminer) with no _external_ plugins.
+This add-on integrates Adminer into your [DDEV](https://ddev.com/) project.
 
 Adminer works with MySQL, MariaDB, PostgreSQL, SQLite, MS SQL, Oracle, and MongoDB.
 
 ## Installation
 
 ```sh
-ddev add-on get ddev/ddev-adminer && ddev restart
+ddev add-on get ddev/ddev-adminer
+ddev restart
 ```
 
-Then you can just `ddev adminer` or use `ddev describe` to get the URL (`https://<project>.ddev.site:9101`).
+After installation, make sure to commit the `.ddev` directory to version control.
+
+## Usage

+| Command | Description |
+| ------- | ----------- |
+| `ddev adminer` | Open Adminer in your browser (`https://<project>.ddev.site:9101`) |
