# USAGE:
#
# Option 1: Build and run tests using specific lotus Git SHA:
#
# > ./test-storage-and-retrieval-local-dev-net.sh --lotus-git-sha=15b3e57634458af983082dcbb736140bba2abfdb
#
# Option 2: Build and run using binaries you've built previously (much faster)

Housekeeping

General rules for making a distributed book club like this not-awful:

• keep your mic muted unless you're speaking
• raise your hand if you have something to say and wait for someone to call on you
• if you're raising your hand and nobody calls on you, type a message into the chat
