First time usage tutorial missing

[saphieron]

For admittedly lack of where else to put this issue:

The current documentation is not precise enough to hand to first time users.

A basic introduction into the different bazel components are required.
Questions that came up during the first time usage:

• What are the different BUILD files for? What has do be defined in the WORKSPACE file?
• How are dependencies added to a newly created project? E.g. the communication library. In which bazel files do we need to change/add things.
• What are the platform options available? in the Communication library some information is give e.g. deps = ["@CommunicationModule//Setup:MotherboardSetup"], but there does not seem to be any documentation that lists the currently implemented platforms or at least where to find them.
• More (cross)documentation needs to be added to get an idea where to look in the other repos

Using CLion:

• How is a newly created project imported?
• What is bazel sync/ blaze? How and when do we use it?
• How does a build configuration have to be defined, to be used in CLion?
• What options exist in the build configuration?

Probably more that I forgot, but they can likely be reproduced by letting someone new try it again.
