 ### Building
 
 The codebase of an _Immutable Web App_ has the responsibility of building static assets and publishing them to a static web server. Each state of the codebase can be represented by a set of static assets at a unique location. Not every state of the codebase needs to be published, but no single state of the codebase should ever need to be published more than once.
 
-Generally the codebase is a source controlled code repository that is capable of building, versioning, and publishing static assets to a static web server.
