Walkthrough

A new tutorial document, "WireGuard Topology", was added to the tutorials directory and included in the tutorials index toctree. The tutorial describes prerequisites and step-by-step UI instructions to create a WireGuard configuration template (including an example JSON for wg0), enable topology visualization, assign the template to devices, and verify the topology with wg show and the Network Topology dashboard. No code, exported/public declarations, or runtime control flow were changed.

🔇 Additional comments (2)

tutorials/index.rst (1)

12-12: toctree entry correctly added.

The tutorial reference is properly registered in the documentation navigation with consistent formatting.

tutorials/wireguard-topology.rst (1)

1-102: No critical RST formatting issues found; cross-references follow established patterns in the codebase.

The RST syntax is valid with properly formatted title underlines, code blocks, and cross-reference directives. The cross-reference pattern (:doc:/controller/user/wireguard``, etc.) is standard throughout this documentation, used identically in tutorials/hotspot.rst, `tutorials/mesh.rst`, `tutorials/wifi-access-point.rst`, and other tutorials. These module-level paths are dynamically built as part of the multi-version documentation process defined in `build.py`, not local files.

Likely an incorrect or invalid review comment.

Thanks for taking a look.

This PR addresses issue #222 by adding a dedicated tutorial that explains how to create a WireGuard topology in OpenWISP. The changes are intentionally kept small and focused , it only adds the new tutorial page and registers it in the tutorials index.

No existing documentation or behaviour was changed beyond that.
I’m happy to update or refine anything if there’s feedback from the reviewers.
