Or to put it nicely.

If you don't want to run docker you can read the Dockerfile as it will contain all of the build step. Then you can enter everything yourself manually.

Most of the time a Dockerfile is a very useful living installation reference documentation, but it's not guaranteed. It's entirely possible to encounter a Dockerfile that's just copying in binaries built outside of Docker or was a published image capture of hand installed stuff that is just being referenced in downstream images.
