 ## Issues
 
+#### Guidelines
+
 When reporting a possible bug, provide detail steps so that we will be able
 to reproduce the issue. Steps to reproduce should be clear and unambiguous. Try not to use phrases like "very big bug",
 "huge issue", "useless feature", etc. No need to use exclamation marks as well.
 
+#### No support
+
 Note that we don't provide developer help or any kind of support on GitHub.
 For this, please use our [forum](https://forum.espocrm.com).
 
+#### Forum
+
 If you are very new to EspoCRM, it's probable that an issue you ran into is not a bug.
 Consider creating a topic on our [forum](https://forum.espocrm.com/forum/general) instead.
 
+#### Project's best interest
+
 The issue tracker is for the benefit of the EspoCRM project. The project maintainers are going to handle issues in the project's best interest.
 The maintainers have right to close issues without explanation.
 
+#### Off-topic
+
 As we reference GitHub issues in release notes, we strive to keep them free of off-topic comments.
