# Introduction

> Create and manage reusable message templates for Persona communications.

Templates are reusable message structures that Personas pull from at send time. They support dynamic variable injection, multi-channel formats, and version control.

## Creating a template

Templates are written in MDX and stored in your connected GitHub repo under `/templates`. Variables are injected using double curly brace syntax:

```mdx theme={null}
Hello {{ contact.first_name }},

Your trial expires on {{ trial.end_date }}.
```
