+## Build Info `<tag>-scratch`
+These images are built from the base ubuntu:18.04 image. They only have one latex layer. They are usually a little bit smaller than their `incremental` counterparts. The `scratch` image is default when used with no tag extension. Also `latest` is built from scratch and is the same as `full` and `full-scratch`.

 Mount your source code at `/data` and run whatever you want with LaTeX.
