## Supported Environments

We currently support Node.js 18 and higher, but support for Node.js 18 and Node.js 20 is deprecated. We strongly encourage
you to use Node.js 22 or higher as we will drop support for Node.js 18 and Node.js 20 in the next major version.
We currently support Node.js 22 and higher.

Please also note that the Admin SDK should only
be used in server-side/back-end environments controlled by the app developer.

The PR description mentions adding "Node.js 26 to CIs", which appears to be a typo (likely intended for Node.js 22). Additionally, this PR is missing updates to CI configuration files (e.g., GitHub Actions workflows) and other package manifests in the repository (for instance, test/integration/postcheck/package.json still references @types/node: >=14.0.0). Please ensure all references to supported Node.js versions are updated consistently across the project.
