Looking for an “easy to understand” description of the tfm file format

Looking for an “easy to understand” description of the tfm file format

I try to understand TeX more deeply, and one part of it is the TFM (TeX font metric) file format. Is there an easy to understand yet complete description of it somewhere (perhaps free)?
I know I can look into the source code (which is what I am doing at the moment), but a nicely formatted article with images would help me understanding the file structure.
I am not looking for an "overall description". The description should be exact (which byte has which meaning), but it should help the reader (=me) with some illustrations and examples.
