+Jabit Server
+============
+
+This is the server node using the Jabit library. You can run it by calling
+```
+java -jar jabit-server.jar
+```
+The interface will be available on port 9000, Bitmessage as usual on Port 8444.
+
+There are still a few problems with the interface (the idea is to allow collecting
+and displaying broadcasts).
+
+On first startup it will create a config file (allowing you to configure the
+Bitmessage port), a whitelist, a blacklist and a shortlist. If the whitelist isn't
+empty, the blacklist will be irrelevant. You can disable the feature by simply
+adding a valid Bitmessage address to the whitelist. For shortlisted addresses, only
+the last five broadcasts are displayed and stored (useful e.g. for time services or
+Q's Aktivlist).
+
+Building / Development
+----------------------
+
+You can build the jar file with
+```
+./gradlew build
+```
+As there is a problem with the build order, you'll need to do this twice.
+
+To deploy on a Ubuntu server (might work on other Linuxes as well), create a file
+`/etc/init/jabit.conf` with the following contents:
+```
+chdir /srv/jabit
+
+exec su -s /bin/sh -c 'exec "$0" "$@"' jabit -- /usr/bin/java -jar jabit-server.jar --server.port=9000 > /dev/null
+
+start on runlevel [2345]
+stop on runlevel [^2345]
+
+```
+there must be a user jabit and a folder `/srv/jabit` where this user has write
+permission containing `jabit-server.jar`.
