make a bunch of changes so complement works again

Well, kinda. It crashed on me after 10 minutes because the tests timed
out like in <https://github.com/matrix-org/complement/issues/394>.
Sounds like this means it's a them problem though.

I want to use Nix to build this image instead in the future but this
will at least make it work for now and give me a reference for while I'm
porting it. I also want to make Conduit natively understand Complement's
requirements instead of `sed`ing a bunch of stuff and needing a reverse
proxy in the container. Should be more reliable that way.

I'm not making this run in CI until the above stuff is addressed and
until I can decide on a way to pin the revision of Complement being
tested against.

-# Running Conduit on Complement
+# Complement
 
-This assumes that you're familiar with complement, if not, please readme
-[their readme](https://github.com/matrix-org/complement#running).
+## What's that?
 
-Complement works with "base images", this directory (and Dockerfile) helps build the conduit complement-ready docker
-image.
+Have a look at [its repository](https://github.com/matrix-org/complement).
 
-To build, `cd` to the base directory of the workspace, and run this:
+## How do I use it with Conduit?
 
-`docker build -t complement-conduit:dev -f complement/Dockerfile .`
-
-Then use `complement-conduit:dev` as a base image for running complement tests.
+The script at [`../bin/complement`](../bin/complement) has automation for this.
+It takes a few command line arguments, you can read the script to find out what
+those are.
