Thank you for this - looks great! I don't seem to have the permissions to create a pull request, so would you mind changing the list to be this:

- [esbuild](https://github.com/evanw/esbuild/blob/main/docs/architecture.md) - Great use of graphics for visualisations and project structure. Includes a list of important principles for the project.
- [Flutter Engine](https://github.com/flutter/flutter/wiki/The-Engine-architecture) - Good use of high level diagrams to show the stack and its parts. Describes the main processes. Describes platform invariants.
- [GitLab](https://gitlab.com/gitlab-org/charts/gitlab/-/tree/master/doc/architecture) - Calls out design decisions.
- [Linux cryptography](https://github.com/torvalds/linux/blob/master/Documentation/crypto/architecture.rst) - Calls out different types of components, provides searchable areas, calls out invariants of different components, and describes structure with diagrams.
- [Neovim](https://github.com/neovim/neovim/blob/master/src/nvim/README.md) - Describes the main processes/lifecycle.
- [Next.js](https://github.com/vercel/next.js/blob/canary/docs/04-architecture/index.mdx) - Breaks architecture into separate files, calls out important dependencies.
- [Oh My Zsh](https://github.com/ohmyzsh/ohmyzsh/wiki/Design) - Describes the initialization process, calls out environment requirements.
- [Redis](https://github.com/redis/redis/blob/unstable/README.md) - Good source code map. Overviews of key files. Good use of documentation comments in-code rather than inline comments.
- [rust-analyser](https://github.com/rust-lang/rust/blob/master/src/tools/rust-analyzer/docs/dev/architecture.md) - Good diagrams, describes entry points and source organisation, discusses architecture considerations.
- [Tauri](https://github.com/tauri-apps/tauri/blob/dev/ARCHITECTURE.md) - Well made source code map, discusses architecture considerations, calls out important dependencies.
- [VS Code](https://github.com/microsoft/vscode/wiki/Source-Code-Organization) - Good use of high-level diagrams. Describes source organisation.

That is reordered alphabetically and with some minor punctuation/name fixes.

Could we have a look at the Next.js entry? I think that must be linking to the wrong file, or the file has changed, or some other issue.

I seem to be able to edit now, so I've sorted the entries, fixed the names, removed the Next.js entry, and updated the Flutter Engine link to the new location.
