 There're two key mappings defined by default:
 
 - `<leader>gl` (normal/visual mode): copy git link to clipboard.
-- `<leader>gL` (normal/visual mode): open git link in default browser.
+- `<leader>gL` (normal/visual mode): open git link in browser.
 
 To disable the default key mappings, set `mapping = false` in `setup()` function
 (see [Configuration](#configuration)).
