-For example, to use some unicode symbols, you could put this in your `vimrc`:
+The default symbols are the equivalent of something like the following:
 
 ```viml
-sign define vimspectorBP text=🔴 texthl=Normal
-sign define vimspectorBPDisabled text=🔵 texthl=Normal
-sign define vimspectorPC text=🔶 texthl=SpellBad
+sign define vimspectorBP         text=\ ● texthl=WarningMsg

+sign define vimspectorPC         text=\ ▶ texthl=MatchParen
 ```
 
+If the signs don't display properly, your font probably doesn't contain these
+glyphs. You can easily change them by deifining the sign in your vimrc. For
+example, you could put this in your `vimrc` to use some simple ASCII symbols:

+```viml
+sign define vimspectorBP text=>>         texthl=WarningMsg
+sign define vimspectorBPCond text=>>     texthl=WarningMsg

+## Customising the WinBar
+
+You can even customise the WinBar buttons by simply running the usual `menu`
+(and `unmanu`) commands.
+
+By default, Vimspector uses something a bit like this:
+
+```viml
+nnoremenu WinBar.■\ Stop :call vimspector#Stop()<CR>
+nnoremenu WinBar.▶\ Cont :call vimspector#Continue()<CR>
+nnoremenu WinBar.▷\ Pause :call vimspector#Pause()<CR>

+nnoremenu WinBar.→\ Step :call vimspector#StepInto()<CR>

+nnoremenu WinBar.⟲: :call vimspector#Restart()<CR>
+nnoremenu WinBar.✕ :call vimspector#Reset()<CR>
+```
+
+If you prefer a different layout or if the unicode symbols don't render
+correctly in your font, you can customise this in the `VimspectorUICreated`
+autocommand, for example:
+
+```viml
+func! CustomiseUI()
+  call win_gotoid( g:vimspector_session_windows.code )
