+on the platform GHC can be provisioned using nixpkgs or by downloading a binary
 distribution. In case of nixpkgs other toolchains (C compiler, Python, shell
 tools) will also be provided by nixpkgs, in case of bindist they will be taken
 from the environment (`$PATH`). The following `--config` options select the
 corresponding combination of operating system and GHC distribution:
 
 |                     |      Linux      |      MacOS      |      Windows      |
 | ------------------- | --------------- | --------------- | ----------------- |
-| Nixpkgs             | (unneeded)      | `macos-nixpkgs` | (unsupported)     |

+| binary distribution | `linux-bindist` | `macos-bindist` | `windows-bindist` |
 
 Hint: You can use Bazel's `--announce_rc` flag to see what options are being
 used for a command in a specific configuration. E.g.
 ```
-$ bazel build //tests:run-tests --config linux-bindist --nobuild --announce_rc
+$ bazel build //tests:run-tests --config linux-nixpkgs --nobuild --announce_rc
 ```
 
 Hint: To avoid repetition you can add your configuration to `.bazelrc.local`.
 ```
-echo "build --config=linux-bindist" >>.bazelrc.local
+echo "build --config=linux-nixpkgs" >>.bazelrc.local
 ```
