Community feedback needed: Add tutorials/faqs describing different usages to the website

[FriederikeHanssen]

Description of feature

We are looking into expanding the documentation by adding tutorials for different usages. For this we would love some community feedback:

What are some questions you asked yourself when starting out? What would you like to see explained in more detail? Where do you find the documentation is lacking?

• How to use sarek with genome not in iGenomes (Canfam4 genome #958)

[egenomics]

• How to use sarek when library was done using UMIs. Starting at different steps (a) UMIs already present in the fastq header, but not in sequence, b) original bcls, etc
• How to provide different parameters for certain tools

As far as I know, --intervals would need to be either a 3 column bed, or a 5 column bed with estimated seconds in the score column. Anything else will/can result in failures (at least with gatk). Would be nice to make this more explicit.
