[PATCH] D66937: [clangd] Fix the stale documentation about background indexing.

[Haojian Wu via Phabricator via cfe-commits]

hokein added inline comments.


================
Comment at: clang-tools-extra/docs/clangd/Installation.rst:363
 
-- Pass an experimental `-background-index` command line argument.  With
-  this feature enabled, clangd incrementally builds an index of projects
-  that you work on and uses the just-built index automatically.
+- the index is saved to the ``.clangd/index`` in the project root;
+- background indexing canb be disable by the ``--background-index=false`` flag;

I think it is important to mention this. For most cases, .clangd/index is in in the project root, right?
