# Labeling Guidelines
Provide labeling instructions and guidelines for labelers during labeling tasks.
The **Labeling guidelines** extension provides instructions for labelers during labeling tasks.
Supported file formats (max 1 MB):
* `.txt`
* `.pdf`
* `.md` : Markdown guidelines support anchor link navigation, allowing users to jump directly to sections from a table of contents.
## Add labeling guidelines
You can add guidelines in three ways:
1. Drag and drop a file into the uploader.
2. Click **Browse files** to upload a file.
3. Click **Recently used** from the three-dot menu to select a file from the library.
Uploading a new guideline will replace the existing one.
Deleting a guideline removes it for all assignees in the project.
