# Introduction

A **Rule Engine** is like a **set of instructions** that follows a **logical condition**. It works based on the principle of **"When certain conditions are met, perform a specific task."** You can think of it as a smart interpreter for **if-then** statements.  The **if-then** statements in this case are called rules.
