+ccls relies on a [JSON compilation database](https://clang.llvm.org/docs/JSONCompilationDatabase.html) specified
+as compile_commands.json or, for simpler projects, a compile_flags.txt.
+For details on how to automatically generate one using CMake look [here](https://cmake.org/cmake/help/latest/variable/CMAKE_EXPORT_COMPILE_COMMANDS.html). Alternatively, you can use [Bear](https://github.com/rizsotto/Bear).
+
+Customization options are passed to ccls at initialization time via init_options, a list of available options can be found [here](https://github.com/MaskRay/ccls/wiki/Customization#initialization-options). For example:
+
+```lua
+local lspconfig = require'lspconfig'
+lspconfig.ccls.setup {
+  init_options = {
+    compilationDatabaseDirectory = "build";
+    index = {
+      threads = 0;
+    };
+    clang = {
+      excludeArgs = { "-frounding-math"} ;
+    };
+  }
+}
+
+```
