+If neither file exists, ccls assumes there is an imaginary `.ccls` with one line: `%clang`.

+This is convenient for trying out a one-file project. `git init` to let the language client know it is a project, e.g. `cd /tmp; mkdir c; cd c; git init; touch a.cc`

 ### Windows
 
 If your project is compiled with MSVC, you may change the compiler driver (`%clang` above) to `clang-cl`, and use the initialization option `clang.extraArgs` to pass three options:

-Make sure you have `.ccls` or [[compile_commands.json]] in your project root. Open a file in the project, run `:LanguageClientStart`.
+First example:

+For a larger project, you'll need [[.ccls|Getting-started#ccls]] or [[compile_commands.json]] in your project root.
 
 These features will work out-of-the-box.

 scan-build is a python package that can generate a compilation database for clang tooling (uses Bear as a backend). This too can be used for any project based on a `Makefile`.
