+- Install `cargo-vcpkg` with `cargo install cargo-vcpkg`, then run `cargo vcpkg build --manifest-path pacman/Cargo.toml` to build the requisite dependencies via vcpkg.
+  - `--manifest-path` is only required if you run it from the root directory; you can omit it if you `cd` into the `pacman` directory first.
   - This is only required for the desktop builds, not the web build.
 - We use rustc 1.86.0 for the build, due to bulk-memory-opt related issues on wasm32-unknown-emscripten.
   - Technically, we could probably use stable or even nightly on desktop targets, but using different versions for different targets is a pain, mainly because of clippy warnings changing between versions.

+# pacman-server
+
+Despite the naming of this crate, it's not a server for the Pac-Man game allowing multiplayer or anything super interesting.
+
+This crate is a webserver that hosts an OAuth login and leaderboard API for the main `pacman` crate to hook into.
+
+## Features
+

+4. Common Server/Client Crate, Basics
+5. Crate-level Log Level Configuration
+6. Span Tracing
+7. Avatar Pixelization
+8. Leaderboard API
+9. React-based Frontend

+11. Simple CI/CD Checks & Tests
+12. API Rate Limiting (outbound provider requests)
+13. API Rate Limiting (inbound requests, by IP, by User)
+14. Provider Circuit Breaker
+15. Merge migration files
+
+## Notes
+
+### Image Handling
+
+Avatar images are stored in S3 as follows:
+
+- `avatars/{user_public_id}/{avatar_hash}.original.png`
+- `avatars/{user_public_id}/{avatar_hash}.mini.png`
+
+- The original image is converted to PNG and resized to a maximum of 512x512 pixels.
+  - Ideally, non-square images are fitted to a square.
+- The mini image is converted to PNG and resized to a maximum of 16x16, 24x24, or 32x32 pixels. TBD.
+- All images receive a Content-Type header of `image/png`.
+
+Image processing is handled immediately asynchronously, allowing a valid presigned URL to be generated immediately.
