+    goal="finish the integration of new modules and work towards the restructuring of the pipeline"
+>
+    This is a pipeline for downstream gene expression analysis, with a main focus on differential expression analysis. Currently, we are working on a new branch `dev-ratio` with two objectives: 
+    
+    - add new methods 
+    - convert the pipeline into a modular and unified framework that allocates different ways of performing differential analysis. 
+    
+    By joining this group you will help with:
+        1) Implement and add nf-core modules that wrap other methods that can be used to perform differential analysis. Some modules (ie. propr) were already created but need to be updated (beginner friendly).
+        2) Add these new modules to the pipeline and update the pipeline parameters correspondingly (beginner friendly).
+        3) Add the existing modules to the new modular subworkflow in a way that will reproduce the original pipeline’s behaviour (beginner - intermediate level).
+        4) Update the code required to generate the plots and reports (beginner - intermediate level).
+        5) Help in the restructuring of the pipeline architecture (intermediate level).
+        6) Update documentation (beginner friendly).
