|Be careful: if you update your map or mod, server operators will have to update the package on their servers (rerun the download tool,) otherwise the version that clients autodownload won't match what's on the server. It's recommended that you include "WIP" ("work in progress") or "Beta" in the Workshop entry if you're regularly updating your map to let server operators know.|
After you have created your map, it is time to upload it to the steam workshop. Thanks to the SDK Frontend tool that Torn Banner provides, this process is relatively painless.
And to adjust the description, title, images, and whether or not it is visible to other users (they are visible by default), use the Owner Controls.
