 ### NixOS
 
-Bazelisk and rules_go does not work on NixOS since its prebuilt binaries are dynamically linked,
-so we cannot bootstrap the sandbox. We recommend building in a "normal" container.
+We fully support building on NixOS, and we provide a `shell.nix` file to make it easy:
+

+
+(just don't look at it too closely unless you want toolchain-themed nightmares)
