# Preview branch

A preview branch is a deploy generated from a pull request, building the site as it would be if the proposed changes were merged. Preview Branches are published to a URL that has the branch name as the prefix. For example, a Preview Branch for branchname will deploy to branchname.live.mrf.io and branchname.mrf.io

# Media Group

An institution that owns one or several publications in the media industry.

# Media Group Repository

Git repository containing the source code of a given Media Group. Mostly static files such as JavaScript, CSS, and images.

# Media Group Deploy Repository

Git repository containing the artifacts generated by any given build in the Media Group Repo. Pushing changes to a branch in the Media Group Repo will automatically trigger a build that will generate artifacts in this repository.

# Production Deploy

A deploy from the production branch. Marfeel has auto-publishing enabled, and the production branch is always master. This means that an update to what is published on the site’s main URL is triggered each time a change lands on master.
