 This is a side project, so feel free to submit a PR for any functionality/bug fixes and go ham. There aren't any contributing guidelines as of yet, code style is handled by `swiftlint` (`$ brew install swiftlint`) and should automatically fix the style upon build (there is a GH Action setup for this also).
 
+### :speech_balloon: Localisation
+
+This project supports localisation! Please see the pinned [language support issue](https://github.com/othyn/macos-auto-clicker/issues/10) as a discussion place for new language support. See the [`auto-clicker/Localisation`](https://github.com/othyn/macos-auto-clicker/tree/main/auto-clicker/Localisation) project directory to view currently supported languages, the project default being `en-GB`.
+
+The project makes use of the Apple default `Localizable.strings` and `Localizable.stringsdict` to support local translations. See [issue #36](https://github.com/othyn/macos-auto-clicker/issues/36) for some useful links and resources for implementing translations. The short tutorial is;
+
+0. Clone this project locally to somewhere on your machine.
+1. Open up the project **workspace** in Xcode.
+2. Click on the top level project item in the project file browser sidebar in Xcode.
+3. Click on the project under the Project heading.
+4. Click on the 'Info' tab.
+5. Scroll down to 'Localizations'.
+6. Click the plus button at the bottom of the table displaying the current project languages and select the language you intend to provide translations for.
+7. On the on screen prompt **change nothing** and just click 'Finish'
+8. The new language will appear in the `Localisation` folder as a new version of the `Localizable.strings` file, with the language code identifier along with the file and appearing as the parent directory in the `Localisation` folder. E.g. for France this would be `fr`. You will know if the translation file has been picked up by Xcode as the language will appear with the amount of `Localizable.strings` translation files found by Xcode in that 'Localizations' table mentioned in step 5.
+9. Once you have written the translations by providing the appropriate new strings in the language you've chosen as are required by the application, please submit a new PR to merge in the new language as a supported language.

+
+More information on Apple's localisation practices can be found on [their official docs](https://developer.apple.com/localization/), and [their official docs for Xcode](https://developer.apple.com/documentation/xcode/localization). There is also an application, [`mohakapt/Stringz`](https://github.com/mohakapt/Stringz), who's sole intent is to make writing and maintaining language translations easier. See [issue #36](https://github.com/othyn/macos-auto-clicker/issues/36) for some more useful links and resources for implementing translations.
