 Use of these features require a python toolchain to be registered.
 `//py_images/image.bzl:deps` and `//py3_images/image.bzl:deps` register a
-default python toolchain (`//toolchains/python:container_py_toolchain`)
+default python toolchain (`//toolchains:container_py_toolchain`)
 that defines the path to python tools inside the default container used
 for these rules.
 
 ### Known issues
 
 If you are using a custom base for `py_image` or `py3_image` builds that has
 python tools installed in a different location to those defined in
-`//toolchains/python:container_py_toolchain`, you will need to create a
+`//toolchains:container_py_toolchain`, you will need to create a
 toolchain that points to these paths and register it _before_ the call to
 `py*_images/image.bzl:deps` in your `WORKSPACE`.
