 ## Installation and Usage
 
-1. Head over to the [Releases](https://github.com/bozbez/win-capture-audio/releases) page and download the latest installer (or zip if you are using a portable installation)

+1. Head over to the [Releases](https://github.com/bozbez/win-capture-audio/releases/tag/v2.1.0-beta) page and download the latest installer (or zip if you are using a portable installation)
+2. Run the setup wizard, selecting your root OBS folder (`obs-studio/`, _not_ `obs-studio/obs-plugins/`) when asked (or extract the zip to the portable OBS root directory)
 3. Launch OBS and check out the newly available "Application Audio Output Capture" source
+
+## Troubleshooting
+
+- **Application Audio Output Capture source not showing up after install:** this means that either your OBS is out-of-date (check that it is at least 27.1.x) or you have installed the plugin to the wrong location. To re-install, first uninstall via "Add or remove programs" in the Windows settings, and then run the installer again. Make sure to select the top-level `obs-studio/` folder in (probably) `C:/Program Files/`.
+
+- **Application Audio Output Capture source not picking up any audio:** this happens when your Windows is too old and does not have support for the API. Note that even if you have a more recent major version such as `20H2` you will still need the latest updates for the plugin to work. If you are on a very old version you might need more than one update for this to work, and the second update might not show up for a few days after the first update.
