 ## Getting Started
 
-We are using node 18.x and npm 8.x. If you are [using nvm](https://github.com/nvm-sh/nvm#installing-and-updating), there is an [.nvmrc](.nvmrc) file, so just run `nvm install` to get the latest 18.x/8.x versions (or set up your environment to [automatically switch](https://github.com/nvm-sh/nvm#deeper-shell-integration)). Otherwise, download from the [node homepage](https://nodejs.org/en/download/).
+We are using node 24.x and npm 11.x. If you are [using nvm](https://github.com/nvm-sh/nvm#installing-and-updating), there is an [.nvmrc](.nvmrc) file, so just run `nvm install` to get the latest 24.x/11.x versions (or set up your environment to [automatically switch](https://github.com/nvm-sh/nvm#deeper-shell-integration)). Otherwise, download from the [node homepage](https://nodejs.org/en/download/).
 
 In order to use the UI, you must also be running a [deephaven-core](https://github.com/deephaven/deephaven-core) server on port 10000. The server provides APIs that the web-client-ui depends upon. An easy way to get started is to launch a Deephaven container from the [quick start guide](https://deephaven.io/core/docs/tutorials/quickstart/).
