## How to use the interface?

⚠️ Most errors are due to:
- A wrong `tag` -> the tag must exist on the repository!
- A wrong `branch` -> The branch must exist on the repository!
- A wrong `token` -> Obtaining a token is detailed below.

### token

This is a personal access token generated by GitHub. You can obtain one with the following guide:
https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token.

### Repository

The repository for which to create the release notes. Should be in the format `organization/repository`.

### Tag

The tag from which all commits were made. The app will fetch the date at which this tag was created, and will
return all commits of the branch defined below that have a timestamp following that date.

### Branch

The branch on which all commits lie. Usually `master` or `main`.

### Threshold

This threshold allows highlighting specific community contributors according to the size of their contributions.
It currently adds all their additions/deletions across all PRs included in this release. It is then compared
to the defined threshold: if above, that user will get a special note mentioning what they have worked on!
