# Usage (without browser extension)

## Notice

> **It is recommended to use this Jira app with browser extension, since the combination provides the flexibility to write LaTeX in everwhere: Summary, Description, Comment, custom fields, etc. Please see the instructions here** [**https://fulstech.gitbook.io/docs/latex-for-jira/jira-cloud/usage-with-browser-extension**](https://fulstech.gitbook.io/docs/latex-for-jira/jira-cloud/usage-with-browser-extension)**.**

## Overview

After installing and starting the trial period, the app will add a custom field name **LaTeX text** to the Jira instance.

The first step is to add the custom field **LaTeX text** to issue types and projects.

## For classic Jira projects

### Associate the LaTeX custom field to issue screens

ax^2 + bx + c = 0
{latex}

{latex}
x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}
{latex}
```
