+Install [vim-lsc](https://github.com/natebosch/vim-lsc) according to the instructions in its README.
+
+Configure ccls as the language server (example for `cpp`, do similarly for other filetypes, as needed):
+
+```viml
+let g:lsc_server_commands = {
+\ 'cpp': {
+\    'command': 'ccls',
+\    'message_hooks': {
+\        'initialize': {
+\            'initializationOptions': {'cache': {'directory': '/tmp/ccls/cache'}},
+\            'rootUri': {m, p -> lsc#uri#documentUri(fnamemodify(findfile('compile_commands.json', expand('%:p') . ';'), ':p:h'))}
+\        },
+\    },
+\  },
+\}
+```
+
+If the [compilation database](https://github.com/MaskRay/ccls/wiki/compile_commands.json) is correctly set, then things should work (e.g. reference highlight of the symbol under the cursor should be visible). See `|lsc-commands|` for the list of all available commands.
+
+Default mappings are provided out-of-the-box (see `|lsc-default-map|`). To set custom mappings, change the values in `|g:lsc_auto_map|`, e.g.:
+
+```viml
+let g:lsc_auto_map = {
+\  'GoToDefinition': '<M-d>',
+\  'FindReferences': '<M-r>',
+\}
+```
+
+(optionally add `'defaults': v:true` to keep default values for other mappings that are not redefined).
