I followed this guide: http://wiki.dreamfactory.com/DreamFactory/Installation :
$ git stash
$ git checkout master
$ git pull origin master
//self-update is optional, try it if you get an error without it
$ ../../../php/bin/php composer.phar self-update
$ ../../../php/bin/php composer.phar install --no-dev
$ ../../../php/bin/php artisan migrate --seed
$ ../../../php/bin/php artisan cache:clear
$ ../../../ctlscript.sh restart
Didn't see any errors, believe it was succesfull. Would you recommend to run these lines again?
