Improvements on docs

[douglasmiranda]

• Deployment docs
• Set clear goals of the project on README
• Describe what I mean with "setup close to production" since the development is with Docker Compose and deployment with Docker Swarm and that may be confusing. (I'm actually talking about specific parts like focusing on not having a requirements.txt for prod, decisions I've made on the Django Dockerfile, configuration...)
• Maybe add a TODO in the README, so people know what I'm working on
• Deployment: Storage
