Using vim-plug:

Plug 'autozimu/LanguageClient-neovim', {
    \ 'branch': 'next',
    \ 'do': 'bash install.sh',
    \ }

" (Optional) Multi-entry selection UI.
Plug 'junegunn/fzf'

Example configuration

" Required for operations modifying multiple buffers like rename.
set hidden

let g:LanguageClient_serverCommands = {
    \ 'rust': ['~/.cargo/bin/rustup', 'run', 'stable', 'rls'],
    \ 'javascript': ['/usr/local/bin/javascript-typescript-stdio'],
    \ 'javascript.jsx': ['tcp://127.0.0.1:2089'],
    \ 'python': ['/usr/local/bin/pyls'],
    \ 'ruby': ['~/.rbenv/shims/solargraph', 'stdio'],
    \ }

" note that if you are using Plug mapping you should not use `noremap` mappings.
nmap <F5> <Plug>(lcn-menu)
" Or map each action separately
nmap <silent>K <Plug>(lcn-hover)
nmap <silent> gd <Plug>(lcn-definition)
nmap <silent> <F2> <Plug>(lcn-rename)

Run command nvim +PlugInstall +UpdateRemotePlugins +qa in shell to install this plugin. Install corresponding language servers. Restart neovim/vim and language services will be available right away. Happy hacking!
