+## Node Version Configuration
+
+This repository provides flexibility to manage Node.js versions in CI workflows using repository variables.
+These variables can be configured at the repository level via the [Actions settings page](https://github.com/salesforcecli/plugin-lightning-dev/settings/variables/actions).
+These can also be supplied as arguments to individual workflows directly.
+
+### `UT_DISABLE_NODE_CURRENT`
+
+- Disables the latest Node.js version in GitHub Actions workflows.
+
+### `UT_DISABLE_NODE_PREVIOUS`
+
+- Disables the previous Node.js version in GitHub Actions workflows.
+
+### `NODE_VERSION_OVERRIDE`
+
+- Overrides the full set of Node.js versions used for testing and publishing.
+- **Default:** `'lts/*'` and `'lts/-1'`.
