-# MarkdDairy Web App
+# MarkDairy Web App
 
+The app allows you to write your diary and use your Github as storage for dairy records.
+
+## Configuration
+
+1. [Create a GitHub repository](https://github.com/new).
+   It is recommended to make it `private` unless you do not want everybody to read your records.
+2. Create [fine-grained personal access tokens](https://github.com/settings/tokens?type=beta) with
+   `"Contents"` repository permissions (write).
+3. Open the app and configure your repository and token.
