-# Rankup3
-
-## Installation
-
-Rankup can be compiled with the `gradle build` command. The compiled plugin jar will be in the `/build/libs` directory.
-
-## Translation
-
-If you would like to contribute to translating the plugin, you can fork it.
-Locale names are in ISO-639-1 and are in the folder [`src/main/resources/locale`](https://github.com/okx-code/Rankup3/tree/master/src/main/resources/locale)
-
-When a locale is added, it should be saved [here](https://github.com/okx-code/Rankup3/blob/master/src/main/java/sh/okx/rankup/Rankup.java#L242), ie through adding a line such as `saveLocale("es");`. However, I can do it if you forget.
-
-You can use the [English](https://github.com/okx-code/Rankup3/blob/locale/src/main/resources/locale/en.yml) locale to help translate.
-
-Locales should be added or modified with a pull request, but if you wish to contribute often I can give you push access to this branch.
