Evervolv is a colaborative effort. To submit patches sign up on Gerrit. Please note we do not accept pull requests on Github

Submit a change to the vendor/ev project adding your device to the vendorsetup.sh script ( remember to keep your devices name in order). Include the device and dependent projects that need to be forked. If any changes to other projects are necessary for your device bringup, make sure to submit these changes at the same time. If you still need help, contact either preludedrew or drewis on irc.
