### How to add a Text tool to your project
From the project’s *Settings* tab, enter the *Label Set* section.
Click on *Add Category*. From the list that appears, click on *Text*.
A new row will appear named *Text*. Click on it to expand it.
### Text Tool Options
**Schema ID**: The unique ID assigned to the tool.
**Title**: The name of your labeling tool.
**Required**: If you enable this toggle, labelers will be required to answer this field before saving.
**Regex Validation**: If you enter a regular expression in this field (without the initial and final `\` slashes), labelers' answers to this field will have to match the regex being input before saving.
**Rich Text Editor**: If enabled, the user will not see a plain text field, they will instead see a rich text editor where they can make text bold, italic, add images, and more. This is then stored and served in the export as HTML.
**KaTeX Preview**: If enabled, you may have annotators see a live preview of KaTeX, a mathematical subset of LaTeX:
**Frame-specific**: If you enable this toggle, the answer to this classification will only be valid for one frame (in videos and multi-frame images/DICOMs) instead of the whole asset.
**Multiple**: If enabled, annotators can answer this classification multiple times.
Once you have selected your options, click on *Save* at the bottom to save your changes.
