#DevOps Tuesdays!

What?

• Sign up to pair with Krishnan (and others) to work on real-world DevOps tasks one day of the week every week, and get going with specific knowledge, skills, and practice!

When?

• Every Tuesday (or another day of the week in the event that holidays or vacation intervene). So there's always something happening every Tuesday, and some Tuesdays, you'll be knee-deep in it!

How?

• We’ll pick people at random and let you know beforehand. No pre-requisites whatsoever!
