+### Customize background padding
+CodeSnap allows you to customize the padding of background using `bg_x_padding`, `bg_y_padding` and `bg_padding`, the default value is:
+```lua
+require("codesnap").setup({
+  bg_x_padding = 122,
+  bg_y_padding = 82,
+  bg_padding = null
+})
+```
 
+If you want to hide background, you can set `bg_padding` to `0` in your config:
+```lua
+require("codesnap").setup({
+  -- ...
+  bg_padding = 0
+})
+```
 
 ## Watermark
 Watermark is something that makes screenshots more personalized, but if you don't like watermark just set it as an empty string to hide it.
