write a proper README

[nweldev]

For now, README.md is just the one generated by default by angular-cli. We should had informations about the course itself (slides link, timing, how to use the steps, etc...).

Do you want a french or english version?

[nweldev]

I think a french one would be better given that we only give this in french, but not sure. I should check with @cbalit.

[geromegrignon]

i thought so but given the issues are in english, i wanted to make sure!
I'll start a french template and translate it later on if required.

[nweldev]

Yeah, maybe we should use french here too 😄 I'm just used to write everything in english on Github ...
Great idea thx!

[nweldev]

Ok for a french version, but as their is some chance that this school may be given in english in a near futur, we'll keep issues and commits in english, and we'll also need an english versiion of this README later.

Pull request done.

Once the #93 will be completed, i'll consider adding a "Learning materials" section with links to additional content like :

• ngrx.io
• angular console
