# Introduction

This documentation in this section is a copy of the official MathOptInterface documentation available at https://jump.dev/MathOptInterface.jl/v1.1.1. It is included here to make it easier to link concepts between JuMP and MathOptInterface.

## What is MathOptInterface?

MathOptInterface.jl (MOI) is an abstraction layer designed to provide a unified interface to mathematical optimization solvers so that users do not need to understand multiple solver-specific APIs.

This documentation is aimed at developers writing software interfaces to solvers and modeling languages using the MathOptInterface API. If you are a user interested in solving optimization problems, we encourage you instead to use MOI through a higher-level modeling interface like JuMP or Convex.jl.

## How the documentation is structured

Having a high-level overview of how this documentation is structured will help you know where to look for certain things.

- The
**Tutorials**section contains articles on how to use and implement the MathOptInteraface API. Look here if you want to write a model in MOI, or write an interface to a new solver. - The
**Manual**contains short code-snippets that explain how to use the MOI API. Look here for more details on particular areas of MOI. - The
**Background**section contains articles on the theory behind MathOptInterface. Look here if you want to understand*why*, rather than*how*. - The
**API Reference**contains a complete list of functions and types that comprise the MOI API. Look here is you want to know how to use (or implement) a particular function. - The
**Submodules**section contains stand-alone documentation for each of the submodules within MOI. These submodules are not required to interface a solver with MOI, but they make the job much easier.
