[nathanshammah]

Add information in the readme file at https://github.com/matt-lourens/dynamic-qcnn.

Some stuff is standard and existing information that can be summarized in the Readme, other stuff may need to be created. They include:

• introduction: scope of the package
• compatibility
• installation and requirements
• link to examples or documentation
• contribution guidelines information, code of conduct
• license For more information have a look at https://github.com/unitaryfund/mitiq or https://github.com/qutip/qutip, for example. Some information are present in this guide https://github.com/nathanshammah/make-your-code-count.

Feel free to ping me, @stephendiadamo or Unitary Fund advisors for questions.

I'll add a pull request that adds some Sphinx documentation structure. Will help organize things like examples and further details.

Hey guys, if you're happy with the following changes we can close the ticket. The documentation is live with tutorials for each framework. I've also updated the readme + added files for the standard info that @nathanshammah mentioned. The package is also published on pypi now: https://pypi.org/project/hierarqcal/
