To pack your mod on Windows, select your modinfo, modicon, and assets folder, and right click on one of the files. In the context window, hover over "7-zip", and then select "Add to archive...". When entering a name for your zip file, most mods follow the format of "modid-version". This allows users of your mod to easily differentiate between the version of mod you are using. Select 'OK' and your zip file will be created.
