# Tutorials

9 hands-on tutorials, each producing a concrete outcome. Grouped by difficulty — start at **Beginner** if new to aDNA, or jump to **Intermediate** if you already have a vault and a CLAUDE.md.

## Beginner — Start here (≈ 50 min total)

Three tutorials to build your foundation. **Start with [Navigate an aDNA Vault](/learn/tutorials/navigate-a-vault)** (no prerequisites), then Create Your First CLAUDE.md, then Apply the Question Test. By the end: a working vault, a CLAUDE.md, and a way to classify any piece of project knowledge.

## Advanced — Scale and connect (≈ 90 min total)

Compose executable workflows, run phased campaigns, share lattices across instances. Prerequisites: at least one Beginner + one Intermediate tutorial.

[Build a Lattice 30 minutes — A validated .lattice.yaml file that defines a workflow as a directed graph of nodes and edges. By the end, you'll have a composable…](/learn/tutorials/build-a-lattice)[Adopt via the Exchange: Pull → Build-to-Spec → Memorialize 35 minutes — Walk the full aDNA adoption arc end-to-end: pull a shared piece of work, build it to the standard, and memorialize where it came from.](/learn/tutorials/exchange-adoption-path)[Federate a Vault 30 minutes — A federated connection between two aDNA instances — exporting a lattice from one project, importing it into another, and composing it into a…](/learn/tutorials/federate-a-vault)[Run a Campaign 30 minutes — A campaign document with phased execution, a mission board, and quality gates.
