Install instructions need work

[kpu]

• [ ] https://github.com/paracrawl/Domain_Adaptation/blob/master/INSTALL.md doesn't render properly on github.
• [ ] Do I need to compile Moses or just download it for the tokenizer? Why Moses and not just the Moses tokenizer extract like https://github.com/kpu/preprocess/ or the one Marcin made?
• [ ] Do I need to compile kenlm? Does it need the python bindings?
• [ ] Correct the spelling of download.
• [ ] Perhaps make a paths configuration file part of the installation instructions.
