Herald is a simple daemon watching the systemd journal and sending selected messages over XMPP. It can be used as a simple server monitoring solution.

1. Install the herald package for your distribution (preferred), or install from source (Go 1.11 or later is required):

   make
   sudo make install

2. Edit /etc/herald/config.toml. You should at least set up your XMPP server and credentials, and the list of recipients.
3. sudo systemctl enable --now herald.service

Herald will look for its configuration file in several locations in the following order:

1. The path given as -config PATH argument in the command line,
2. config.toml in the current working directory,
3. /etc/herald/config.toml,
4. /etc/herald.toml.

See etc/config.toml for a commented example.
