 The MITK Project Template
 =========================
 
 This project provides a complete CMake-based set-up to get started with [MITK](https://github.com/MITK/MITK).
 
 Features
 --------
 
 - Example module
   - ITK-based image filter
   - Interactor to paint in images
 - Example command-line app
   - Uses the image filter of the example module
 - Example plugin
   - GUI for the image filter and interactor of the example module
 - Example external project
   - Microsoft's Guidelines Support Library (GSL)
 
-What's new in v2018.04
-----------------------
+How it works
+------------
 
-The project template was completely restructured to fit the new extension
-mechanism of MITK v2018.04. Here's how it basically works:
-
-1. Clone the latest stable branch `releases/2018-04` of MITK from https://phabricator.mitk.org/source/mitk.git (not yet available on GitHub)
-2. Clone MITK-ProjectTemplate
+1. Clone [MITK](https://github.com/MITK/MITK) and checkout the latest release tag or at least the stable master branch
+2. Clone MITK-ProjectTemplate and checkout the matching tag or branch
 3. Configure the MITK superbuild and set the CMake cache variable `MITK_EXTENSION_DIRS` to your working copy of the project template
 4. Generate and build the MITK superbuild
 
-The project template is integrated right into the MITK superbuild and MITK build. Thus you can extend MITK with your own modules, plugins, command-line apps, and external projects without touching the MITK source code. There is no need for a super-superbuild anymore as compared to earlier versions of the project template.
+The project template is virtually integrated right into the MITK superbuild and MITK build as if it would be part of MITK. You can extend MITK with your own modules, plugins, command-line apps, and external projects without touching the MITK source code resp. repository.
