 Note: Like the `g:easytags_always_enabled` option, if you change this option it won't apply until you restart Vim, so you'll have to set this option in your [vimrc script] [vimrc].
 
+### The `g:easytags_updatetime_min` option
+
+Vim has a setting which influences how often the plug-in is automatically executed. When this setting is too low, the plug-in can break. For this reason the plug-in warns you when ['updatetime'][updatetime] is lower than 4000 milliseconds. If you really want the plug-in to be executed more than once every 4 seconds (without a warning) you can lower the minimum acceptable updatetime by setting this option (number of milliseconds).
+
+### The `g:easytags_updatetime_autodisable` option
+
+Other plug-ins may lower the ['updatetime'][updatetime] value in certain contexts, e.g. insert mode in the case of the [neocomplcache][neocomplcache] plug-in. By setting this option to 1 (true) you can configure the easytags plug-in so that it doesn't give warnings about the updatetime option but instead skip updating and highlighting while the updatetime is set too low. When the updatetime is restored to a reasonable value the plug-in resumes.

 ### The `g:easytags_auto_update` option
 
 By default the plug-in automatically updates and highlights your tags when you stop typing for a moment. If you want to disable automatic updating while keeping automatic highlighting enabled you can set this option to false:
