+# GitHub Profile Views Counter
+
+It counts how many times your profile was viewed.
+
+![Profile View Counter Example](https://user-images.githubusercontent.com/1849174/87232647-40ba1080-c3c9-11ea-9d50-c6778edcd8c7.png)
+
+## Usage
+
+Create your GitHub Profile repository. If you will name a new repository equally to your username — GitHub magic will happen.
+
+Here is my profile: [https://github.com/antonkomarev/antonkomarev](https://github.com/antonkomarev/antonkomarev)
+
+You need to host this app on your server and display it via Markdown syntax:
+
+```markdown
+![](https://komarev.com/github-profile-views-counter)
+```
+
+Only `public/index.php` should be exposed.
+
+This URL will render SVG image with views counter and will increment it on each view of your profile.
