+### [V contributing guide](https://github.com/vlang/v/blob/master/CONTRIBUTING.md)
+
+V would be much less, than what it is today, without the help of all
+its contributors. If you like and want to help the V project succeed,
+please read that document, choose a task, and dive in!
+
+### [V language documentation](https://docs.vlang.io/introduction.html)
+The site has the same information as this document, but split to pages,
+for easier reading on mobile devices. Updated automatically on each
+commit to the main repository.
+
+### [V standard module documentation](https://modules.vlang.io/)
+The site has the documentation of all the modules in V's standard
+library (vlib). Updated automatically on each commit to the main
+repository.
+
+### [V online playground](https://play.vlang.io/)
+The site allows you to enter and edit small V programs, then compile
+and run them. Updated automatically on each commit to the main
+repository. Use it, to test your ideas, when you do not have access
+to a computer or an Android phone, where V has been already installed.
+
+### [Awesome V](https://github.com/vlang/awesome-v)
+When you make a cool new project or a library, you can submit it to that
+list too. You can also use the list, for ideas about new projects to do
+with V.
+
+### [The V language Discord](https://discord.gg/vlang)
+This is the place to be, to discuss the V language, learn about latest
+developments, quickly get help with issues, witness/participate in
+~~epic flame wars~~ constructive criticism exchanges and design decisions.
+Join it, and learn more about languages, games, editors, people, Klingons,
+Conway's law and the universe.
