Write user guide, update README

I want to only use the genetic distance from inputted sequence alignments to get the cut-off values, is that possible?
BTW, if construct trees, can I use other softwares, like fasttree, phyml, raxml?

@liamxg - I'm in the middle of fixing the main branch, I'll try to update the examples as soon as I can ok?

Could you please show an example of builds clusters from inputted sequence alignments, not phylogenetic trees, to determine the cut-off values, thanks

Dear @ArtPoon,
wow, amazing.
