+# Project Requirements
+
+This root requirements folder branches into sub-folders depending on the python package.
+Within the folder, we have grouped requirements files/lists per focus, which shall closely match package extra
+So, for example, when you install PL as `pip install pytorch-lightning[loggers]`, this list is stored in `requirements/pytorch/loggers.txt`.
+The only exceptional requirement file is `devel.txt`, which aggregated all the needed requirements for development.
+
+## CI/CD upper bounds
+
+For Ci stability, we have set for all package versions upper bounds (the latest version), so with any sudden release, we won't put our development on fire.
+The continues updated of these upper bounds are managed by dependabot.
+Note that these upper bounds are lifters when installing a package from the source or as a package.
+If you want to preserve/enforce restrictions on the latest compatible version, add "strict" as an in-line comment.
