## ADD
ADD <src> <dest>
ADD <src>... <dest>
The `ADD` instruction will copy new files from `<src>` and add them to the
container's filesystem at path `<dest>`.
The `ADD` instruction copies new files,directories or remote file URLs to
the filesystem of the container from `<src>` and add them to the at
path `<dest>`.
`<src>` must be the path to a file or directory relative to the source directory
being built (also called the *context* of the build) or a remote file URL.
Multiple <src> resource may be specified but if they are files or
directories then they must be relative to the source directory that is
being built (the context of the build).
`<dest>` is the absolute path to which the source will be copied inside the
destination container.
