 Remap for the bepo layout in Lua, inspired from https://github.com/michamos/vim-bepo
 
 It aims to be faster (takes only 0.4ms at startup on my machine, while vim-bepo requires 1.6ms)
+
+## Example Use Case
+
+``` lua
+require("bepo").setup()
+```
+
+You can also apply only some mapping groups:
+``` lua
+require("bepo").movement()
+require("bepo").tabs()
+require("bepo").easy_access()
+require("bepo").window()
+```
