# Getting started

CGE-Core v0.8 has two levels of use.

**Practitioner path:** start with `SimpleCGE`, `StandardCGE`, `CamCGE`, or `IFPRICGE`.
The bundled model owns routine closure and solver plumbing.

**Advanced lower-level path:** use `CGE`, `PyCGE`, model definitions, and `.raw` when
you need implementation-level control or inspection.
