+## Branches
+
+### Web UI
+
+We will be using the `web-ui-v1.x` branch to manage the upcoming Web UI `v1`
+release. Any hotfix releases for Web UI `v0.x` will happen on the `main` branch
+until `v1` is released, at which point a `web-ui-v0.x` branch will be created to
+support any `v0.x` bug fixes.
