First build is timing out

My build keeps timing out. I was reading that you can somehow change the build timeout setting but not sure how to do that. Can someone assist? Also, as a follow up question, this is my first build. Will subsequent builds take less time because the node modules will already have been installed?

And the answer to your question is typically yes, the build cache will be maintained for subsequent builds, which should help speed things up.
