About GitHub releases

La page des versions contient le code et les fichiers d’installation pour toutes les versions de développement de Scratch Addons, ainsi que le miroir des versions du magasin.

Clonage du répertoire

This is the recommended way to install Scratch Addons for development purposes, assuming you have Git installed.

If you plan on contributing, fork the repository on GitHub first and then clone the fork, replacing <username> with your Github username.

$ git clone<username>/ScratchAddons.git

Pour mettre à jour Scratch Addons, commencez par cd dans son dossier, puis exécutez les commandes suivantes.

$ git fetch
$ git pull

Remember to also update Scratch Addons from the browser.

Downloading the Zip

This method is not recommended for development unless Git cannot be installed on the system since it will need to be manually repeated every time you update Scratch Addons.
