+# ⚠️  NOTE: THIS IS A FORK
+
+This is a fork of the original symbols-outline.nvim which merges some selected
+PRs from the original repo, plus some other improvements due to personal
+preferences.
+
+It does not attempt to be an up-to-date successor of the original repo, nor does
+it attempt to ensure everyone's use-cases are satisfied by providing an overall
+better experience. It is merely a fork which I maintain for my personal
+use-cases which incorporates some selected PRs.
+
+## Maintenance status
+
+This fork is NOT guaranteed to be completely bug-free, nor as stable as the
+original. However, since I use this plugin myself, it is guaranteed that
+selected issues that I encounter myself would be fixed (to the best of my
+ability).
+
+I do not merge PRs from the original repo that I don't personally need.
+
