+# Aqua Server
+An multipurpose game server power by Spring Boot.
+
+### Supported Game:
+* CHUNITHM Amazon
+* Project DIVA Arcade Future Tone
+
+### Usage:
+Requirements:
+* Java 11 or above
+* MySQL (Optional)
+
+Just run `java -jar aqua.jar`
+
+or use the `start.bat` if you are using windows.
+
+User data will be save in data/db.sqlite.
+If you switch to MySQL, it will auto create the table and import some initial data.
+
+Auto creation won't work with Sqlite, so if you want to recreate the database please use the file come with the release
+
+### Configuration:
+Configuration is save in `application.properties`
+
+If you are going to deploy on other machine, you must change the `allnet.server.host` and `allnet.server.port` to the IP or Hostname of the hosting machine.
+This will be send to the game at booting and being used by following request.
+
+And you can switch to MySQL(MariaDB) database by commenting the Sqlite part.
+
+### Other Information:
+This server provide a simple API for changing some DIVA's setting.
+
+A Web App can be found on https://github.com/samnyan/aqua-viewer
+
+Live Version: http://aqua.samnyan.icu/
+
+And DIVA screenshot will be save in data folder.
+
+### Credit:
+* **samnyan**
+* **Akasaka Ryuunosuke** : providing all the DIVA protocol information
+* All devs who contribute to the MiniMe server
