2. What's Swagger?
=> Swagger allows you to describe the structure of your APIs so that machines can read them. The ability of APIs to describe their own structure is the root of all awesomeness in Swagger, can automatically build beautiful and interactive API documentation, can also automatically generate client libraries for your API in many languages and explore other possibilities like automated testing.

3. CRUD?

4. Relationship between frontend, backend, database
