Update README

We barely changed the content since 2015 while irctest changed a lot.
This commit better reflects the current project goals, status, and removes unmaintained
software from the examples.

 This project aims at testing interoperability of software using the
 IRC protocol, by running them against common test suites.
 
+It is also used while editing [the "Modern" specification](https://modern.ircdocs.horse/)
+to check behavior of a large selection of servers at once.
+
 ## The big picture
 
 This project contains:
 
-* IRC protocol test cases
-* small wrappers around existing software to run tests on them
+* IRC protocol test cases, primarily checking conformance to
+  [the "Modern" specification](https://modern.ircdocs.horse/) and
+  [IRCv3 extensions](https://ircv3.net/irc/), but also
+  [RFC 1459](https://datatracker.ietf.org/doc/html/rfc1459) and
+  [RFC 2812](https://datatracker.ietf.org/doc/html/rfc2812).
+  Most of them are for servers but also some for clients.
+  Only the client-server protocol is tested; server-server protocols are out of scope.
+* Small wrappers around existing software to run tests on them.
+  So far this is restricted to headless software (servers, service packages,
+  and clients bots).
 
 Wrappers run software in temporary directories, so running `irctest` should
 have no side effect.
 
+Test results for the latest version of each supported software, and respective logs,
+are [published daily](https://dashboard.irctest.limnoria.net/).

 ## Test selection
 
 A major feature of pytest that irctest heavily relies on is test selection.
 Using the `-k` option, you can select and deselect tests based on their names
-and/or markers (listed in `pytest.ini`).
 For example, you can run `LUSERS`-related tests with `-k lusers`.
