[cfe-dev] [clangd] Newcomers guide

[Ilya Biryukov via cfe-dev]

Hi Balogh,

It's not that bad, e.g. last time I checked the index for LLVM takes
<200MB. That's not small, but manageable.
Obviously, larger projects may end up being really huge, but I still
encourage you to try it out, maybe it'll work for your use-case too.

But you're definitely right, keeping some of the index out of memory might
turn out to be hard requirement for larger projects.
