 Currently, a number of tools **must** be installed on your machine in order to
 run the tests:
 
+* ``bazel`` - As with all other development, Bazel is required to actually
+  build the project as well as end-to-end test framework. Bazel will also
+  retrieve appropriate versions of any other dependencies depending on what
+  'target' you choose to run.
+
 * ``docker`` - We provision a whole Kubernetes cluster within Docker, and so
   an up to date version of Docker must be installed. The oldest Docker version
   we have tested is 17.09.
 
-* kind_ - This
-  tool is responsible for actually building and starting the Kubernetes cluster
-  used during tests.
-
-* helm_ - A minimum version 2.10 is required.
-
 * ``kubectl`` - If you are running the tests on Linux, this step is
   technically not required. For non-Linux hosts (i.e. OSX), you will need to
   ensure you have a relatively new version of kubectl available on your PATH.
 
-* ``golang`` - We require golang to build cert-manager and various test
-  related components. You should use at least go version 1.9, although we
-  currently build with go 1.11 in our own CI.
-
 * An internet connection - tests require access to DNS, and optionally
   Cloudflare APIs (if a Cloudflare API token is provided).

-
-.. code-block:: shell

-   go install github.com/kubernetes-sigs/kind
