Installation
The master branch is async-only and thus requires at least Vim 8.0.902. Use
the legacy branch for older Vim versions.
Using your favorite plugin manager, e.g. vim-plug:
if has('nvim') || has('patch-8.0.902')
  Plug 'mhinz/vim-signify'
else
  Plug 'mhinz/vim-signify', { 'branch': 'legacy' }
endif
Configuration for async update
" default updatetime 4000ms is not good for async update
set updatetime=100
