+# * last_committed_tag=v1.26.1 last_released_tag=v1.26.0 ./snap/part-gitea-pull.sh

 summary: Gitea - A painless self-hosted Git service
 description: |
   The goal of this project is to make the easiest, fastest, and most painless
-  way of setting up a self-hosted Git service. With Go, this can be done with
-  an independent binary distribution across ALL platforms that Go supports,
-  including Linux, Mac OS X, Windows and ARM.
+  way of setting up a self-hosted Git service with GitHub-like experiences,
+  including issue tracking, code review, project management, wikis, packages registry,
+  GitHub Actions and more.
