Is your feature request related to a problem? Please describe.
Add documentation so that users know which endpoints are available, the parameters they require and any known limitations that they should be aware of in advance, e.g. basic tier users having a limit of 5 requests per minute

Describe the solution you'd like
The README should outline the project but also provide documentation for users so that anyone can easily use the API simply by cloning the project, running it and following the documentation
