 ### Refreshing lualine
+
 By default lualine refreshes itself based on timer and some events. You can set
 the interval of the timer with refresh option. However you can also force
 lualine to refresh at any time by calling `lualine.refresh` function.
+
 ```lua
 require('lualine').refresh({
   scope = 'tabpage',  -- scope of refresh all/tabpage/window
   place = { 'statusline', 'winbar', 'tabline' },  -- lualine segment ro refresh.
 })
 ```
+
 The arguments shown here are default values. So not passing any of them will be
 treated as if a default value was passed.
 
 So you can simply do
+
 ```lua
 require('lualine').refresh()
 ```

 You can also disable lualine completely.
 Note that you need to call this after the setup
+
 ```lua
   require('lualine').hide({
     place = {'statusline', 'tabline', 'winbar'}, -- The segment this change applies to.
     unhide = false,  -- whether to re-enable lualine again/
   })
 ```
+
 The arguments show for hide above are default values.
 Which means even if the hide function is called without
 arguments it'll work as if these were passed.
 
 So in short to disable lualine completely you can do
+
 ```lua
 require('lualine').hide()
 ```
+
 To enable it again you can do
+
 ```lua
 require('lualine').hide({unhide=true})
 ```
