Documentation - not a bug.

I am using Python version 3.9.7 and h5py version 3.7.0 on Windows 10 OS. These were acquired through a company Artifactory account. I have been working with HDF files as a primary source of data storage for the last two years, converting data from csv, numpy, pandas, and Nastran HDF outputs, primarily generating mapped compound datasets. In building converters for numpy and pandas data, I had some difficulty in finding documentation on the required format of compound datatypes.

I believe that new users could benefit from more thorough documentation of the format required to generate compound datasets manually, especially for datatypes not native to HDF (like boolean) or from numpy or pandas conversion. Given the amount and qualify of the documentation present, I believe the community would benefit from a brief description in the datsets.rst and perhaps an example file or two as a way for the new user to get started.

I would be willing to contribute to this effort and eager to receive and incorporate input on various methods, as my experience is still limited.
