This page is the first point for anyone interested in contributing to Elektra!
+## GSoC 2018
+
+This page is also the central point for students interested in contributing to Elektra during
+[Google Summer of Code 2018](https://summerofcode.withgoogle.com).
+
+Google Summer of Code is a opportunity for you to get paid while working on free software
+initiatives during summer:
+
+- [Timeline is available here.](https://developers.google.com/open-source/gsoc/timeline)
+- [Flyers can be found here.](https://developers.google.com/open-source/gsoc/resources/media)
+
+> Disclaimer: We do not yet know if we will participate!
+
+### Which GSoC projects are available?
+
+We think that GSoC is a perfect opportunity to bridge Elektra and other free
+software projects. So the ideal GSoC project is to elektrify some free software.
+
+Elektra may be used for applications (frameworks) like KDE, GNOME,
+and LXCE or for any applications that need to read configuration files,
+access environment variables, or command-line parameters.
+
+Some possible tasks are:
+
+- Integrate applications (or frameworks) into Elektra.
+- Arbitrary nesting of plugins.
+- Expore further ways of how configuration can be validated.
+- The Qt-GUI could be improved by integrating validation.
+
+## What are the requirements to participate?
+
+- At least one PR submitted to Elektra (see below for details).
+- Fluent in English or German
+- Good writing skills in English
+- Profound programming skills with focus on good code quality, documentation and unit tests.
+- Ideally experience with an application (framework) or even author of a FLOSS application
