Patching Webkit Proposal - LemontechSA/TideSDK GitHub Wiki
Basic Setup
Checkout WebKit from git://git.webkit.org
Create a branch (say tidesdk-patches) as git checkout -b tidesdk-patches
Configure it to push/pull from the TideSDK repo (git remote add -t tidesdk-patches tidesdk git://github.com/TideSDK/TideSDK-WebKit && git config branch.tidesdk-patches.remote tidesdk)
Updating WebKit
git checkout master
git pull
git rebase master tidesdk-patches (with your fingers crossed, you'll get rebase conflicts if something breaks)
