 ## How to Contribute
 
 ### Reporting Bugs
 
-If you find a bug, please file an issue.
+If you encounter a bug and have found a way to reliably reproduce it on the latest `main` branch, please file a [bug report](https://github.com/sxyazi/yazi/issues/new?template=bug.yml) with a [minimal reproducer](https://stackoverflow.com/help/minimal-reproducible-example).
 
 ### Suggesting Features
 
-If you have a feature request, please file an issue.
+If you want to request a feature, please file a [feature request](https://github.com/sxyazi/yazi/issues/new?template=feature.yml). Please make sure to search for existing issues and discussions before submitting.
 
 ### Improving Documentation
 
-Yazi's documentation placed at [yazi-rs/yazi-rs.github.io](https://github.com/yazi-rs/yazi-rs.github.io), contributions related to documentation need to be made within this repository.

+
+### Improving Icons
+
+Yazi's icon originates from [`nvim-web-devicons`](https://github.com/nvim-tree/nvim-web-devicons), and it is periodically grabbed and updated with the latest changes from upstream via [`generate.lua`](https://github.com/sxyazi/yazi/blob/main/scripts/icons/generate.lua).
+
+Contributions related to the icon should be made upstream to facilitate easier automation of this process.
 
 ### Submitting Code Changes
