Adding files to a repository associated with a project is very straightforward with HeroEngine. First of all you need to download the repository browser from the hero engine dashboard after you log in to the hero engine website (See step 3 below).
Now that you have the repository browser, open up the file and it will download the assets for your project. Once this has been completed, you can log in and it will open the HeroEngine Repository Browser window.
From here, you can use the local file browser which is located on the upper side of the window to drag files to the remote, which is the lower side of the window. And that’s it, very simple.
