+# Dynamic Profile Page On Github
+
+GitHub Action to push subdirectories to separate repositories.
+
+### Why?
+
+GitHub announced a special repo (github_username/github_username) its README.md file will appear on your profile. People liked it a lot and started using some static pages with fancy texts and images. This GitHub action helps you to add a section that is updated dynamically when you commit a repository that uses this action.
+
+## Usage
+
+Follow the steps;
+- Create your special repository if not exists.
+- Add `<!-- START gadpp -->` add the end of the README.md file of the special repo.
+- Create a personal access token [here](https://github.com/settings/tokens) and set the `repo` permission.
+- Add the access token created in previous step to the repository (that uses this action) as a secret with name `API_TOKEN_GITHUB`.
+- Create the YML file for the action under `.github/workflows`. You can use the sample given below.
