Add your name to the list of members and tell everyone what you'd like to work on. If you're new to Wikipedia, review the Beginners page before getting started.
There are a lot of things that can be done with this project. The goals are listed on the project page, but feel free to create your own tasks. Or you can do some of the suggested ones below.
Use the tools available in the Resources section (the Public art New Article Guide, Public art Style Guide, and Public art Image Guide) to create new articles about public art.
Add {{WikiProject Visual arts |public-art=yes |class=}} to the top of the page.
Check the Public art assessment chart if you'd like to fill out the template with the article's class. (We do not judge the importance level, unlike other projects.)
Ask the owner of the artwork, or the area around it, or an adjacent building, if there's somewhere they could display a QRpedia QR code, linking to the Wikipedia article about it (and/ or the subject or artist)
Consider applying for funding from your local authority, arts organisation, or other sources, or for a Wikimedia/ chapter micro-grant, to pay for the making and fixing of a durable QRpedia plaque
Translate the article for other-language Wikipedias; or seek help from other people who will do so
