How to use the client-server API
================================
TODO(kegan): Tweak joinalias API keys/path? Event stream historical > live needs
a token (currently doesn't). im/sync responses include outdated event formats
(room membership change messages). Room config (specifically: message history,
public rooms)
public rooms). /register seems super simplistic compared to /login, maybe it
would be better if /register used the same technique as /login?

How to use the client-server API
================================
This guide focuses on how the client-server APIs *provided by the reference
home server* can be used. Since this is specific to a home server
implementation, there may be variations in relation to registering/logging in
which are not covered in extensive detail in this guide.
If you haven't already, get a home server up and running on
``http://localhost:8080``.
Accounts

you do not specify a password, you will be unable to login to the account if you
forget the access token.
Implementation note: The matrix specification does not enforce how users
register with a server. It just specifies the URL path and absolute minimum
keys. The reference home server uses a username/password to authenticate user,
but other home servers may use different methods.

A client should repeatedly make requests with the "from" query parameter with
