You don't need experience coding, just know how to fork a repo, modify a couple .md and create a PR. It can all be done from github's webpage, graphically.

I encourage people to PR for 2 reasons:

1) Makes the community aware that the web portal is open source and up for contributions.

2) To get users involved in the process. This is a community project now, after all.

For reference, this is what the PR looked like for this particular change:

https://github.com/goatpig/BitcoinArmory/pull/140/files

Fairly simple. You shouldn't let the lingo deter you. This is a perfect opportunity to learn a little git-fu.
