+   You do not need to run your own Krill Test Bed if you just want to
+   try out Krill. You can simply install Krill on a test machine and
+   set it up under the public Krill based RPKI testbed that NLnet Labs
+   runs here: https://testbed.krill.cloud/
+
+According to the Oxford English dictionary a test bed is *`"a piece of equipment used for testing new machines" <https://www.oxfordlearnersdictionaries.com/definition/english/test-bed>`_*.
+
+Most importantly an RPKI test bed acts as a fake root of an RPKI hierarchy,
+an alternative to the real RPKI hierarchy that allows you to test your use
+of RPKI software, whether relying party or child certificate authority,
+without actually interacting with the real global RPKI hierarchy, i.e. it's
+a safe space to play.
+
+Test Bed mode allows Krill to operate as such a fake root. In order to be
+actually useful it also offers additional services similar to those provided
+by the RIRs in their RPKI service offerings, including:
+
+  - A Trust Anchor including serving a corresponding Trust Anchor Locator.
+  - A root level RPKI Certificate Authority (CA) in the RPKI hierarchy (immediately under the TA).
+  - A publication server for storing objects published under the CA.
+  - A public web interface for 3rd parties to register their CA as a child of this root CA.

-But of course, you are perfectly welcome to run your own Test environment
-as well. That way you have total control over your test environment. This
-may be particularly useful for training purposes, and for testing code integration
-using the API or the RFC 8181 Publication Protocol or RFC 6492 Provisioning
-Protocol.

-Here we will document how we set up a simple testbed. This is not a strict guide.

 You may want to do things differently and that would be fine, but we hope that
 this provides a useful walkthrough.
