# Glossary
This glossary puts in relation continuous deployment terms and Marfeel infrastructure. Reach out to add more definitions!
# 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.
