+# Profile READMEs
+
+To display a Markdown file in your Gitea profile page, simply create a repository named `.profile` and add a new file called `README.md`. Gitea will automatically display the contents of the file on your profile, above your repositories.
+
+Making the `.profile` repository private will hide the Profile README.
