closes #154

[manulera]

I have created a dependency group docs with poetry, that can be installed like this:

poetry install --with docs

This is how it looks in the pyproject.toml file:

[tool.poetry.group.docs.dependencies]
sphinx-autobuild = "^2021.3.14"
numpydoc = "^1.6.0"
sphinx-rtd-theme = "^1.3.0"

I added some instructions to the readme to run a local sphinx server with the changes. I am merging this into the issue_147 branch, so this should be merged before #150.
