+      Gocode is a helper tool which is intended to be integrated with your
+      source code editor, like vim, neovim and emacs. It provides several
+      advanced capabilities, which currently includes:
+
+        - Context-sensitive autocompletion
+
+      It is called daemon, because it uses client/server architecture for
+      caching purposes. In particular, it makes autocompletions very fast.
+      Typical autocompletion time with warm cache is 30ms, which is barely
+      noticeable.
