+Install [ALE](https://github.com/w0rp/ale) following its README.
+
+ALE automatically loads all available linters and LSP clients for the filetype so, if `ccls` is correctly installed, it should work out-of-the-box. Moreover, ALE will automatically detect the root folder of your project.
+
+To set init options for `ccls`, add to `~/.vimrc` or `~/.vim/vimrc` (example for `cpp` files, set other filetypes as needed):
+
+```viml
+let g:ale_cpp_ccls_init_options = {
+\   'cache': {
+\       'directory': '/tmp/ccls/cache'),
+\   },
+\ }
+```
+
+Diagnostic is enabled out-of-the-box. Completion (omnifunc) can be enabled with:
+
+```viml
+let g:ale_completion_enabled = 1
+```
+
+ALE also provides a completion source for [deoplete](https://github.com/Shougo/deoplete.nvim), which should work out-of-the-box if deoplete is installed and enabled.
+
+ALE exposes commands to invoke LSP features (see `|ale|`):
+```viml
+" Example keybindings
+nn <silent> <M-d> :ALEGoToDefinition<cr>
+nn <silent> <M-r> :ALEFindReferences<cr>
+nn <silent> <M-a> :ALESymbolSearch<cr>
+nn <silent> <M-h> :ALEHover<cr>
+```
