The index page looks empty and is not really useful for understanding what Clangd is/how it helps you. Completion is cool but does not advertise Clangd much from the first sight (compiler and Clang-Tidy diags + rename might do that). We can either:

1. Update it: add more info and a couple of interactive demos, link "Features" (this is what most users would be interested in anyway, right?)
2. Point index to the features directly and call it differently/make it "index-aware" (assume this is the first page users land on).
