+MUcomplete is an implementation of chained (fallback) completion, whereby
+several completion methods are attempted one after another until a result is
+returned. The plugin is available here:
+https://github.com/lifepillar/vim-mucomplete.
+
+To enable automatic completion with MUcomplete, use the following options: >
+
+  let g:mucomplete#can_complete = {}
+  let g:mucomplete#can_complete.tex =
+    \ { 'omni': { t -> t =~# g:vimtex#re#neocomplete . '$' } }
