 ## Overview
+
 NvChad's Ui plugin handles the following modules:
+
 - Statusline
 - Tabufline ( bufferline + tablist )
 - NvDash ( Minimal dashboard )
 - Term ( terminal handling )
 
-## Statusline & tabufline 
+## Tabufline and Statusline
 
+- Both of the plugins share the same way to customize their appearance.
 - The order is a list of module names from default modules + your modules
 - Removing a word in the order will remove that module
 - Modules expect all its keys to be a function that returns a string.
+- Statusline modules can also have strings! 
+- To highlight a string in statusline/tabufline,
+  wrap it with your highlight group, or the existing ones from the theme.

 M.ui = {
   tabufline = {
