+## Releases
+
+The Graph CLI is released on [npm](https://www.npmjs.com/package/@graphprotocol/graph-cli) and published as a Binary on [GitHub Releases](https://github.com/graphprotocol/graph-tooling/releases). We support all the version of CLI that support [Maintenance, LTS and Current Node.js releases](https://github.com/nodejs/Release#release-schedule). Additionally if there are `graph-node` specific features that are breaking and no-longer supported, we will drop support for older versions of CLI. After 90 days of a new `Node.js` release, we will drop support for the oldest `Node.js` version.
