Detailed Installation Instructions

I know that there are installation instructions in the readme file of the project. As someone who is new to software development in general, I ran into some issues while setting up the project locally. As a small example, the port number of the Postgres in my computer is 5432 but the below line in the project specifies the port as 5433

TheBestBookOn.com/bestbook/configs/__init__.py

Line 48 in ad899fb

'port': config.getdef('db', 'port', '5433'),

So I will modify the instructions in the readme file to setup the project locally, which will hopefully help newcomers like me.

I had a question before progressing further to submit a PR:
Should I add a new file called contributing.md or modify the existing installation instructions in the readme file itself?

Thanks to @cclauss, for helping me setup it up locally.

I think the default port should indeed be 5432 -- if you'd like to open a PR, that would be great, thank you!
