+name: Bug report
+about: When creating a bug report, please use the following template to provide all the relevant information and help debugging efficiently.
+
+---
+
+**How to post a meaningful bug report**
+1. *Read this whole template first.*
+2. *Determine if you are on the right place:*
+   - *If you were performing an action on the app from the webadmin or the CLI (install, update, backup, restore, change_url...), you are on the right place!*
+   - *Otherwise, the issue may be due to the app itself. Refer to its documentation or repository for help.*
+   - *When in doubt, post here and we will figure it out together.*
+3. *Delete the italic comments as you write over them below, and remove this guide.*
+--- 
+
+### Describe the bug
+
+*A clear and concise description of what the bug is.*
+
+### Context
+
+- Hardware: *VPS bought online / Old laptop or computer / Raspberry Pi at home / Internet Cube with VPN / Other ARM board / ...*
+- YunoHost version: x.x.x
+- I have access to my server: *Through SSH | through the webadmin | direct access via keyboard / screen | ...*
+- Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: *no / yes*
+  - If yes, please explain:
+- Using, or trying to install package version/branch:
+- If upgrading, current package version: *can be found in the admin, or with `yunohost app info $app_id`*
+
+### Steps to reproduce
+
+- *If you performed a command from the CLI, the command itself is enough. For example:*
+    ```sh
+    sudo yunohost app install the_app
+    ```
+- *If you used the webadmin, please perform the equivalent command from the CLI first.*
+- *If the error occurs in your browser, explain what you did:*
+   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. You can remove this section if the command above is enough to understand your intent.*
+
+### Logs
+
+*When an operation fails, YunoHost provides a simple way to share the logs.*
+- *In the webadmin, the error message contains a link to the relevant log page. On that page, you will be able to 'Share with Yunopaste'. If you missed it, the logs of previous operations are also available under Tools > Logs.*
+- *In command line, the command to share the logs is displayed at the end of the operation and looks like `yunohost log display [log name] --share`. If you missed it, you can find the log ID of a previous operation using `yunohost log list`.*
+
+*After sharing the log, please copypaste directly the link provided by YunoHost (to help readability, no need to copypaste the entire content of the log here, just the link is enough...)*
+
+*If applicable and useful, add screenshots to help explain your problem.*

 ## Overview
 
-Airsonic is a free, web-based media streamer, providing ubiquitous access to your music. Use it to share your music with friends, or to listen to your own music while at work. You can stream to multiple players simultaneously, for instance to one player in your kitchen and another in your living room.
+Stream and manage your music collection
 
-Airsonic is designed to handle very large music collections (hundreds of gigabytes). Although optimized for MP3 streaming, it works for any audio or video format that can stream over HTTP, for instance AAC and OGG. By using transcoder plug-ins, Airsonic supports on-the-fly conversion and streaming of virtually any audio format, including WMA, FLAC, APE, Musepack, WavPack and Shorten.
+**Shipped version:** 10.6.2~ynh2
 
-If you have constrained bandwidth, you may set an upper limit for the bit rate of the music streams. Airsonic will then automatically re sample the music to a suitable bit rate.
+**Demo:** https://airsonic.github.io/demo/
-
-In addition to being a streaming media server, Airsonic works very well as a local jukebox. The intuitive web interface, as well as search and index facilities, are optimized for efficient browsing through large media libraries. Airsonic also comes with an integrated Podcast receiver, with many of the same features as you find in iTunes.
-
-**Shipped version:** 10.6.2
