+Thanks for giving yabridge a shot! If you're having issues with plugins not working at all or scans timing out then make sure to check out the [troubleshooting common issues](https://github.com/robbert-vdh/yabridge#troubleshooting-common-issues) section of the readme. `yabridgectl sync` will also try to diagnose most if these issues for you during setup.
+
+**Problem description**
+A short description of the current situation.
+
+**System information**
+- Operating system: [e.g. Manjaro, or Ubuntu 20.04]
+- Wine version: [e.g. Wine Staging 5.13]
+- Installation method: [symlinks/copies], [manual/yabridgectl]
+- yabridge version: [e.g. 1.3.0, or commit a29f43a]
+
+**Debug log**
+Please also include a debug log if possible. If you are having issues with yabridgectl, then you can omit this section.
+
+1. First make sure that there are no left over Wine processes left running in
+   the background using `wineserver -k`.
+2. Launch your host from a terminal using
+   `env YABRIDGE_DEBUG_FILE=/tmp/yabridge.log YABRIDGE_DEBUG_LEVEL=2 <host>`,
+   e.g. `env YABRIDGE_DEBUG_FILE=/tmp/yabridge.log YABRIDGE_DEBUG_LEVEL=2 bitwig-studio`.
+3. Try to scan or load the plugin that has issues.
+4. `/tmp/yabridge.log` should now contain a debug log. You can either attach
+   this log directly to the issue by dragging the file onto this text box, or
+   you could upload the contents to a website like GitHub gists or Hastebin.
