Open the download page in your browser. 2. Find the latest release or download file. 3. Download the Windows version. 4. If the file is in a ZIP folder, extract it first. 5. Open the app file to start ldpublisher. 6. If Windows shows a security prompt, choose the option to run the file. 7. Keep the files in a normal folder, such as Downloads or Desktop, so you can find them again.

When you open ldpublisher for the first time:

1. Start Steam before you use workshop tools.
2. Make sure Left 4 Dead 2 is installed.
3. Open ldpublisher.
4. Point the app to your L4D2 files if it asks for a game folder.
5. Load a project or open a mod folder.
6. Review the file list before you publish or pack anything.

Use ldpublisher to keep workshop items in order. You can review content, check files, and prepare items for upload.

The app can help with VPK files, which are common in Source engine modding. You can unpack files to edit them and pack them again when you are done.

If you build skins, maps, sounds, or small addon files, ldpublisher gives you a place to organize the work before you publish.

The app helps with the steps between file work and workshop upload. That makes the process easier to follow.
