Setting up

0. get a device capable of running beeps and bloops, after this called "server".
1. install docker on your server.
2. on your server, fill in PATH_TO_DIR_FOR_DATA_HERE to a local dir where whapp-irc can store stuff and IP_ADDRESS_OR_DOMAIN_HERE to the hostname accessible from other computers (in particular the ones where you want to connect from), and run:

docker run -d \
	--name whapp-irc \
	-v PATH_TO_DIR_FOR_DATA_HERE:/root \
	-p 6667:6060 \
	-p 3000:3000 \
	-e "HOST=IP_ADDRESS_OR_DOMAIN_HERE" \
	lieuwex/whapp-irc

3. setup a new server for whapp-irc in your irc client, if your client is up-to-date with the IRCv3 kids you can add the server-time and whapp-irc/replay capabilities.
4. connect to the created server in step 3.
5. a chat to status should be opened, providing you with a URL to a QR code you should scan using WhatsApp on your phone, afterwards a message 'logged in' should appear. whapp-irc is now fetching your chats, wait until you get a 'ready for new messages' and you should be good.
6. enjoy!

whapp-irc stores information in the dir provided in step 2, you shouldn't have to rescan the QR code every time. The gateway can be a bit slow and sometimes still gives you a new QR code, you can ignore that. If for some reason nothing happens after you connect, try reconnecting and maybe even restarting the docker container (docker restart whapp-irc)
