I've written a (heavily commented) script to automate setup of a block explorer for the beta2 testnet on Ubuntu 16.04. It uses @str4d's fork of zcash with the patches needed to run the Insight block explorer on bitcore.
I'll be updating it to support future release candidates and of course when things go live with the Genesis block on the 28th.
Please leave any feedback or questions here or hit me up on Slack!
