# 🟢 Beginner

**The core runtime: bind, resolve, categorize, scope, and clean up.**

Begin with ordinary Python classes and a small, complete object graph. This level
uses the public `import melder as md` surface and the three core lifetimes:
`unique`, `many`, and `unique_per_conduit`.

## Start here

[Run Hello Melder](../examples/hello-melder.md) to see the whole rhythm in one script.

## What you will learn

- Register classes, functions, and existing instances.
- Bind, conjure once, and resolve through a conduit.
- Use names, binding names, and spellframes as addresses and categories.
- Choose shared, fresh, and scoped instances.
- Create child scopes and make cleanup part of application ownership.
- Read errors and assemble the beginner capstone.

## When to continue

Stay here for a self-contained application. Continue to
[Intermediate](../intermediate/index.md) when configuration, module registration,
or cooperation between subsystems becomes useful.
