Nit: I would say to build the in-tree compiler and std. Which is exactly why in practice this is usually more useful for contributors if they actually need to produce std-using programs or run tests.

I probably also would use ./x build library, I think I never used ./x build std myself. Though I guess I might even drop ./x build rustc or ./x build compiler for that matter, and only say something like:
./x build library-> produce stage 1 rustc/std toolchain./x build library --keep-stage-std=1-> if there's only compiler changes that do not need to rebuild std

I prefer rustc/std over compiler/library since the latter feels less precise, especially since they are also directory names. Am also concerned of expanding this intro section more (and it already does point to --keep section, though I see now it was removed 257e73f).

I don't think "std" is an alias for "library". std will not build proc_macro and test, for example.
