-## v2 Migration Guide
-
-The v1 to v2 upgrade brought a few notable **breaking changes**. To migrate, make the following updates:
-
-- The `type` output is now an empty string instead of `'none'` when no release occurs
-  ```diff
-    - run: echo "Version changed!"
-  -   if: ${{ steps.publish.outputs.type != 'none' }}
-  +   if: ${{ steps.publish.outputs.type }}
-  ```
-- The `--ignore-scripts` option is now passed to `npm publish` as a security precaution. If you define any publish lifecycle scripts - `prepublishOnly`, `prepack`, `prepare`, `postpack`, `publish`, `postpublish` - run them explicitly or set the `ignore-scripts` input to `false`.
-  ```diff
-    with:
-      token: ${{ secrets.NPM_TOKEN }}
-  +   ignore-scripts: false
-  ```
-- The workflow's `.npmrc` file is no longer modified. If you have any workarounds to adjust for this misbehavior - for example, if you're using `actions/setup-node` to configure `.npmrc` - you should remove them.
-
-  ```diff
-    - uses: actions/setup-node@v3

-
-- The `check-version` and `greater-version-only` options have been removed and replaced with `strategy`.
-  - Use `strategy: all` (default) to publish all versions that do not yet exist in the registry.
-    ```diff
-      with:
-        token: ${{ secrets.NPM_TOKEN }}
-    -   check-version: true
-    -   greater-version-only: false
-    +   strategy: all
-    ```
-  - Use `strategy: upgrade` to only publish versions that upgrade the selected tag.
-    ```diff

+## Migration guides
+
+Major releases of the action and libraries may contain breaking changes, documented here.
+For more detailed change logs, see [releases][].
+
+### v2 to v3
+
+The v3 release does not require any changes to how you use `npm-publish` from `v2`. The version of Node.js used by the action was updated to v20 due to GitHub Action's [deprecation of Node.js v16][node16-deprecation]. The minimum required version of Node.js for the library and CLI remains v16.
+
+[node16-deprecation]: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/
+
+### v1 to v3
+
+The v2 release made several breaking changes to inputs, outputs, and behaviors that were present in `v1`. The examples below focus on the action, but the same changes are applicable to the library and CLI, too.
+
+#### v2 option changes
+
+The `check-version` and `greater-version-only` boolean options were replaced with the `strategy` option:
+
+- `strategy: all` (default) will publish any version that does not yet exist in the registry
+- `strategy: upgrade` will publish only if the version is a semver upgrade of the requested `dist-tag`
+
+```diff
+  with:
+    token: ${{ secrets.NPM_TOKEN }}
+-   check-version: true
+-   greater-version-only: false
++   strategy: all
+
+  with:
+    token: ${{ secrets.NPM_TOKEN }}
+-   check-version: true
+-   greater-version-only: true
++   strategy: upgrade
+```
+
+`check-version: false` has been removed. If you only need to publish, without first checking whether the version exists in the registry, you can [use `npm` directly][publishing-nodejs-packages] instead:
+
+```diff
+  - uses: actions/setup-node@v3
+    with:
+      node-version: '18'
++     registry-url: https://registry.npmjs.org/
+
+- - uses: JS-DevTools/npm-publish@v1
+-   with:
+-     token: ${{ secrets.NPM_TOKEN }}
+-     check-version: false
++ - run: npm publish
++   env:
++     NODE_AUTH_TOKEN: ${{ secrets.NPM_TOKEN }}
+```
+
+[publishing-nodejs-packages]: https://docs.github.com/actions/publishing-packages/publishing-nodejs-packages
+
+#### v2 output changes
+
+The `type` output is now an empty string instead of `'none'` when no release occurs
+
+```diff
+  - run: echo "Version changed!"
+-   if: ${{ steps.publish.outputs.type != 'none' }}
++   if: ${{ steps.publish.outputs.type }}
+```
+
+#### v2 behavior changes
+
+The `--ignore-scripts` option is now passed to `npm publish` as a security precaution. If you define any publish lifecycle scripts - `prepublishOnly`, `prepack`, `prepare`, `postpack`, `publish`, `postpublish` - we recommend you run that logic as a separate explicit build step.
+
+```diff
++ - run: npm run build
+
+- - uses: JS-DevTools/npm-publish@v1
++ - uses: JS-DevTools/npm-publish@v3
+    with:
+      token: ${{ secrets.NPM_TOKEN }}
+```
+
+If you can't change your build, you can set the `ignore-scripts` input to `false` as a workaround. Be aware that failures during a lifecycle script can be difficult to debug, and any `stdout`/`stderr` output from your build script could interfere with how `npm-publish` interprets results from the `npm` CLI.
+
+```diff
+- - uses: JS-DevTools/npm-publish@v1
++ - uses: JS-DevTools/npm-publish@v3
+    with:
+      token: ${{ secrets.NPM_TOKEN }}
++     ignore-scripts: false
+```
+
+The global `.npmrc` file is no longer read nor modified. This means the `token` option is now required for the library and CLI. (It was already required for the action.) You may have workarounds in place referencing `INPUT_TOKEN`, which v1 [erroneously wrote][#15] to `.npmrc`. These workarounds should be removed.
+
+```diff
+  - uses: actions/setup-node@v3
+    with:
+      node-version: '18'
+      registry-url: https://registry.npmjs.org/
+
