+### Pylint
+
+> Pylint is a tool that checks for errors in Python code, tries to enforce a
+> coding standard and looks for code smells.
+
+See `pylintrc` for configuration. Be aware that pylint is slow to do its work,
+just be patient.
+
+To check for errors:
+
+    pipenv run pylint gargantext
+
+To get a full report with a dependency graph:
+
+    pipenv run pylint -r y gargantext
+    # To review a particular module pass its folder to pylint:
+    pipenv run pylint -r y gargantext/backend
