+# A GitHub start is important
+
+**GitHub stars** allow netdata to expand its reach, its community, especially attract people with skills willing to contribute to it.
+
+Compared to its first release, netdata is now **twice as fast**, has all its bugs settled and a lot more functionality. This happened because a lot of people find it useful, use it daily at home and work, **rely on it** and **contribute to it**.
+
+**GitHub stars** also **motivate** us. They state that you find our work **useful**. They give us strength to continue, to work **harder** to make it even **better**.
+
+So, give netdata a **GitHub star**, at the top right of this page.
+
+Thank you!
