Learn the node model
Step-by-step tutorials for installing packs, building graphs, and publishing to the [fix]net marketplace.
Getting started
Start here →Install your first pack
Open the store, find a pack that fits your workflow, and install it into the [fix]net app in two taps — no copy-paste, no manual download.
Understand versions and updates
Every pack version is immutable once published. Learn what that means for changelogs, compatibility, and how to safely update a pack your graph depends on.
Build your first graph from a pack
Start from a contributed graph, wire it to your data, and run it — the fastest path from 'installed a pack' to 'something is actually working'.
