+Steps to create a new module Abc
+
+1. Duplicate the skeleton of module located in QualityControlModules/Skeleton.
+2. Call it Abc
+3. Use a (smart) editor to find and replace all occurrences of Skeleton by Abc
+4. Make sure to rename the include/Skeleton to include/Abc as well
+5. Rename all files (Skeleton->Abc)
+6. Near the end of the file QualityControlModules/CMakeLists.txt add `add_subdirectory(Abc)`
+7. Compile
+
+From here, fill in the methods in AbcTask.cxx, and AbcCheck.cxx if needed.
+
+In case special additional dependencies are needed, create a new bucket in QualityControlModules/cmake/QualityControlModulesDependencies.cmake.
