Anyways, after you have finished the details, click on 'Upload to Steam!' and the tool should pack your mod together and load it onto the steam databases. You can now give your mod a name (aka the name it will be shown as in the game itself), a title (the name which is shown while browsing the workshop), a description, version number and even a preview image (definitely upload one, it helps tremendously gaining traffic) If your metadata is renamed and structured correctly it should read the information from it.

Choose 'Select Mod Directory' and browse the subfolder you created (in our case it would be in Starbound/mymods/'yourmodname/'. Alternatively you can also directly start the exe in the win32 folder in your Starbound folder. Now, go to your steam library and either rightclick Starbound or start it and choose the 'Mod Uploader Tool'.

The _ at the end here is for windows user, it enables you to name a file with only an ending. }-save the txt file, rename it to '_metadata_' or '.metadata_'.
