off-target predictions to prioritize list of sgRNA designs

Question

[Anand Rao]

Greetings!

Is there a tutorial / manual for the command line version of CHOPCHOP that explains

1. how to design sgRNAs for non-human genome (not available on their web version)
2. predict off-target(s)
3. select best performing sgRNAs for each target locus

There are some resources available at

1. https://bitbucket.org/valenlab/chopchop/src/master/README.md, and

2. discussion threads under issues at https://bitbucket.org/valenlab/chopchop/issues

Do users here on BioStars know of any additional resources - like an actual tutorial perhaps?

Thanks in advance
