$ okfctl bundle init mykb
Initialized OKF bundle in mykb

$ okfctl node new concepts/tannin.md --type Reference --title "Tannin" --bundle mykb
Created mykb/concepts/tannin.md

$ okfctl node list --bundle mykb
concepts/tannin.md                       Reference

$ okfctl index build mykb
Wrote 2 index.md file(s) under mykb
