+### Contributing
+
+π-Base Graph Theory's data and software are open-sourced on [GitHub](https://github.com/pi-base/).
+We rely on [volunteers like yourself](https://github.com/pi-base/data-graphs/graphs/contributors)
+to [contribute](https://code4math.zulipchat.com/#narrow/channel/416467-pi-base) new graphs, graph classes, and theorems.
+
+### About
+
+π-Base Graph Theory is a companion to the [topological π-Base](https://topology.pi-base.org),
+applying the same object-property-theorem model, with automated deduction, to graphs and the classes they belong to.
+
+In 2026, [the π-Base project](https://pi-base.org) officially expanded to serve disciplines beyond topology.
+
+### Community
+
+The π-Base is part of the [code4math](https://code4math.org) community.
+Join the conversation on our [code4math Zulip channel](https://code4math.zulipchat.com/#narrow/channel/416467-pi-base).
