Unpack the dist tarball on two hosts. On each host:
Modify the example/voter deployment.xml file to specify to hostcount=2.
<deployment>
<cluster hostcount="2" sitesperhost="2" kfactor="0" />
<httpd enabled="true">
<jsonapi enabled="true" />
</httpd>
</deployment>
Edit the run.sh. Change the 9th line (LEADER="localhost") to:
LEADER=<one-of-your-hostnames>
Execute ./run.sh.
