# AToMPM Documentation

This documentation serves to introduce AToMPM to the two main user groups: language developers and language users. AToMPM (“A Tool for Multi-Paradigm Modelling”) is a (meta)modelling workbench, which allows language developers to create visual domain-specific languages, and domain experts to use these languages. A language is defined by its abstract syntax in a metamodel, its concrete syntax(es), which define(s) how each abstract syntax element is visualized, and its semantics definition(s), either operational (a simulator) or translational (by mapping onto a known semantic domain). AToMPM supports model transformations to model semantics.
