 - Display changes in a Terraform plan without posting larger sections of the plan change log. This approach will, in most cases, avoid the situation where plan contents are too large for a single PR comment. 
 - Collapsed as a summary by default, when expanded, the comment is broken up into sections for  deletion, creation, and resource changes. The changes are also color-coded to help draw attention to each proposed modification.
 - This JavaScript GitHub Action runs directly on a host runner and executes faster than a Docker container Action.
+- Possibility to add the output to your workflow summary.
+- Possibility to hide previous comments generated by this action.
+- Possibility to not create any comments in case there are no infrastructure changes.
+- Customize the header and the footer of the generated output.

+## Example usage with OpenTofu
+
+To use this action with OpenTofu you need to initialize OpenTofu without the wrapper, like discussed in the `known issues` below.
+
+**You also need to convert the planfile to a JSON planfile using the `tofu show -json` command.**
+
+```yaml
+  - uses: opentofu/setup-opentofu@v1
+    with:
+      tofu_wrapper: false
+
+  - name: Create planfile
+    run: tofu plan -no-color -out=./.planfile

+  - name: Convert planfile to JSON planfile
+    run: tofu show -json ./.planfile >> ./my-planfile.json
