+The *g:easytags_async* option
+
+By default vim-easytags runs Exuberant Ctags and updates your tags file in the
+foreground, blocking Vim in the process. As your tags files get larger this
+becomes more annoying. It has been the number one complaint about vim-easytags
+since I published the first release online.
+
+In version 3.5 of the vim-easytags plug-in support for asynchronous tags file
+updates was added. It's not enabled by default yet because I want to make sure
+I'm not breaking the plug-in for the majority of users. However after I've
+gathered some feedback I definitely want to make this the default mode.
+
+By setting this option to true (1) you enable asynchronous tags file updates.
+Good luck! ;-)
+
+Note that asynchronous updates on Windows currently require the installation of
+my vim-shell [12] plug-in (for obscure technical reasons that I want to fix but
+don't know how yet).
