+#### How to add a language
+
+If you wish to add a language please follow these steps:
+
+* Go into the `src/localize/languages/` folder
+* Duplicate the `en.json` and name it as the language that you would like to add by following the [2 characters ISO language code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes)
+* Then modify the `localize.ts` file, located in `src/localize/` to include your language file.
+* Update the `Readme.md`, found in `src/` to include your language and your Github username in the language table.
