If GitHub Discussions are not visible in your repository, the feature may be disabled in settings. To activate Discussions, go to your repository’s *Settings*, navigate to the *Features* section, and check the box labeled 'Discussions'. This enables a dedicated tab for Discussions in your repository, allowing community interactions and threaded discussions. If you don’t see this option, ensure you have the necessary permissions to modify repository settings, as only repository administrators can enable or disable Discussions. Once enabled, the Discussions tab will appear next to *Issues*, providing a collaborative space for community members to ask questions, share feedback, and propose ideas in an organized manner.
