     curl https://raw.github.com/IonicaBizau/gh-contributions/master/installer.sh | sh
 
+Usage
+-----
+
+The installer script will create a folder in `home` called `gh-contributions`. So enter in that folder (`cd ~/gh-contributions`) and run `node server` or directly:
+
+```
+node ~/gh-contributions/server.js
+```
+
+The application runs on the port `9000`. Open your browser at `http://localhost:9000/` there you will see the contribution designer. You will draw the commits. A JSON object is generated:
+
+```JSON
+{
+    "coordinates": [
+        {
+            "x": ...,
+            "y": ...
+        },
+        ...
+        {
+            ...
+        }
+    ],
+    "commitsPerDay": 40
+}
+```
+
+Edit the `commitsPerDay` value. That sets the day commit count.
+Then click the generate button and wait... :-) You can delight with the debug messages from terminal while the repository is generated.
+
+After the repository is finished you will get a link for download. Unzip the zip file, add your remote git repository and run `git push -u origin master`.
