-Adjust highlight colours for virtual text:
-
-```
-highlight ActionHintsDefinition guifg=#add8e6
-highlight ActionHintsReferences guifg=#ff6666
-```
-
 ## Usage
 
-Note that for now the component must be included in the lualine for the virtual text to
-be updated.
-
 As a lualine component:
 
 ```lua
 require("lualine").setup({
-  sections = {
-    lualine_x = { require("action-hints").statusline },
-  },
+	sections = {
+		lualine_x = { require("action-hints").statusline },
