Be explicit, use COPY over ADD

At first glance it looks like COPY and ADD does the same thing but there is a difference. ADD is able to extract TAR files as well, which COPY can't do. So be explicit and use COPY when you mean to copy files and ensure to only use ADD when you mean to use something feature specific like the mentioned TAR extraction.

For web developers, this might include things like :

```
   MVC, MVVM, etc.
```
```
  Refactorings

  OOP principles

  Other paradigms like functional programming

  Application deployment
```
```
  Able to own features
```

For database developers, it might include:
