 Trainings
 =========
 
+S-CORE offers hands-on trainings, which you work through in a GitHub repository, and
+self-paced interactive training portals.
+
+Hands-on Trainings
+------------------
+
+Unlike the training portals below, a hands-on training is a GitHub repository: you copy it into
+your own account and work through task issues, defect branches and prepared pull requests in a
+fictive S-CORE module.

+      Contributor Training
+      ^^^^^^^^^^^^^^^^^^^^
+      Build, review, fix and rebase in a module made from the S-CORE module template, with tracks
+      for the quality, safety and security roles. Self-organised, without a tutor; the solutions
+      are open. Ends with a certificate of completion, which is no Eclipse Foundation
+      certification. Further tracks are planned.
+
+      | **Duration:** about five working days
+      | **Stages:** 7 (environment to formal review)
+      | **Tracks:** quality · safety · security
