go to https://github.com/shirioko/WART, click 'download ZIP', unzip to your computer, click the .exe file, done. You need to enter your phone number, you will get a text message containing a 6-digit code. Enter that code into WART and you will get another code. After that, no idea waiting for instructions from coderus!

for sqlite3 via warehouse, sorry didn't read your message properly. I have the same problem! Warehouse says 'package sqlite is not user package'
