+======================
+Take Advantage of Tags
+======================
+
+Tags work like keywords or labels that will help you to categorize your work, as well as make
+objectives and goals clearer and available for everyone instantly. They are also a useful source of
+filtering, helping you to boost productivity.
+
+
+Where can I use and how do I create tags?
+=========================================
+
+| Tags can be used in numerous applications going from *CRM*, *Project*, *Contacts*, *Marketing
+  Automation*, etc.
+| On *CRM* for instance, under :menuselection:`CRM --> Configuration --> Tags` you can create new or
+  edit existing ones.
