+Flamenco is a Blender Foundation project, and is also part of Blender's GSoC
+programme.
+
+## Hints & Tips
+
+The most important tip: **use your own brain. Show that you can think and find
+information yourself. This will greatly increase your chance of acceptance.** So
+congratulations, you found this page! That's a good start.
+
+Another way to increase your chances: **don't over-sell your skills**. Using
+Flamenco once or twice is not enough to say you "*know Flamenco*". If you don't
+know all of the programming languages and techniques used in the project, that
+doesn't have to be any problem. But discuss it. For example, saying "*I've never
+used Go*" is fine, but do make it explicit that this is the case, and also
+explain why you think it's fine to still apply for joining this Go-based
+project.
+
+When you link to your work to show off your skills, that's great! But make sure
+that it is clear **what was written by you, and what was written by somebody else**.
+If the Git history only has commits in your name, and there is no description
+like "copied code from ${LOCATION} as a starting point", then realise that the
+rest of the world will think this is your code. Be careful, this could be seen
+as plagiarism. Many Open Source licenses require you to credit the original
+authors.
+
+And finally: **be part of the community**. Join the chat, use Flamenco, get
+involved. Communicate with your mentor. If you have questions, pop in the
+Flamenco chat channel and ask them (but please also scroll back a little to see
+if someone else already asked the same thing). Flamenco is an open project, and
+that also means discussing things openly. That way everybody can help you answer
+questions, and everybody can benefit from the answers you get.
+
+## Getting Started
+
+There is a lot of documentation already on how to get started with GSoC:
+
+- [Flamenco's Getting Started][flamenco-start] page.
+- [Blender's GSoC: Getting Started][blender-gsoc] page.
+- [Blender's guidelines on contributing code][contributing] also applies to
+  Flamenco. Be sure to give it a read-through, as it has useful information and
+  will make the whole process of getting your changes into Flamenco a more
+  pleasant one.
+- The [Go documentation][go-doc] is pretty good. If you're not familiar with the
+  language, this is a great place to start learning about it.
+- And finally, there's a list of [good first issues][first-issues] that should
+  be relatively simple to resolve, and thus may be a nice way into the project.
+
+Make sure you [join the chat room][chat] to discuss your ideas, ask questions,
+or just to introduce yourself.
