+about: Create a report to help us improve Libation
+title: ''
+labels: bug
+assignees: ''
+---
+
+PLEASE FILL OUT THE FOLLOWING. Bug reports with limited information or lacking an attached log file may get limited or delayed help.
+
+___
+
+## Describe the bug  
+A clear and concise description of what the bug is.
+
+## To Reproduce  
+Steps to reproduce the behavior:
+
+1. Go to '...'
+2. Click on '....'
+3. Scroll down to '....'
+4. See error
+
+## Expected behavior  
+A clear and concise description of what you expected to happen.
+
+## Screenshots  
+If applicable, add screenshots to help explain your problem.
+
+## Platform  
+[e.g. Windows 10, Windows 11, Mac, Linux (State distribution)]
+
+## Log Files
+Attach your Libation log file here. If your user folder contains the file "LibationCrash.log", attach that also.
+
+**Default Log File Locations**
+|Platform|Folder|
+|-|-|
+|Windows|`%userprofile%\Libation`|
+|macOS|`~/Library/Application Support/Libation`|
+|Linux|`~/.local/share/Libation`|
+
+**macOS:** If that folder does not exist because Libation never starts, try launching from Terminal and say whether it works: `/Applications/Libation.app/Contents/MacOS/Libation` (see [Troubleshooting for macOS](https://github.com/rmcrackan/Libation/blob/main/docs/advanced/troubleshoot.md#macos)).
+
+Alternative, you may open the log file folder from within Libation. Open Libation's settings, and on the first tab in Settings you can click the button 'Open log folder'.

+**No-go ideas**  
+There are lots of great ideas and many are beyond what we intend to do for Libation. Some good ideas which we do not intend to pursue:
+
+* comprehensive api/cli
