[searchisko-dev] [doc] Tutorial section added.

[Lukas Vlcek]

Hi,

I added Tutorial section into Searchisko documentation: https://github.com/searchisko/searchisko/blob/master/documentation/tutorials/README.md
The first tutorial is getting started for new Content Providers: https://github.com/searchisko/searchisko/blob/master/documentation/tutorials/getting_started_content_provider.md

Still, it might be too high-level, feel free to let me know if any topic needs further explanation.
