+
+## Quick Start
+
+The easiest way to play is to visit the [online demo][demo]. It is more or less identical to the desktop experience at this time.
+
+While I do plan to have desktop builds released automatically, the game is still a work in progress, and I'm not quite ready to start uploading releases.
+
+However, every commit has build artifacts, so you can grab the [latest build artifacts][build-workflow] if available.

-    - Avatars are optional for score submission and can be disabled, instead using a blank avatar.
-    - Avatars are downscaled to a low resolution pixellated image to maintain the 8-bit aesthetic.
-    - A custom name is used for the score submission, which is checked for potential abusive language.
-      - A max length of 14 characters, and a min length of 3 characters.
-      - Names are checked for potential abusive language via an external API.
-  - The client implementation should require zero configuration, environment variables, or special secrets.
-    - It simply defaults to the pacman server API, or can be overriden manually.

 ## Build Notes
 
 Since this project is still in progress, I'm only going to cover non-obvious build details. By reading the code, build scripts, and copying the online build workflows, you should be able to replicate the build process.
 
+- 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.
-- Install `cargo-vcpkg` with `cargo install cargo-vcpkg`, then run `cargo vcpkg build` to build the requisite dependencies via vcpkg.
 - For the WASM build, you need to have the Emscripten SDK cloned; you can do so with `git clone https://github.com/emscripten-core/emsdk.git`
   - The first time you clone, you'll need to install the appropriate SDK version with `./emsdk install 3.1.43` and then activate it with `./emsdk activate 3.1.43`. On Windows, use `./emsdk/emsdk.ps1` instead.
     - I'm still not sure _why_ 3.1.43 is required, but it is. Perhaps in the future I will attempt to use a more modern version.

     - `caddy file-server --root dist` (install with `[sudo apt|brew|choco] install caddy` or [a dozen other ways](https://caddyserver.com/docs/install))
 - `web.build.ts` auto installs dependencies, but you may need to pass `-i` or `--install=fallback|force` to install missing packages. My guess is that if you have some packages installed, it won't install any missing ones. If you have no packages installed, it will install all of them.
   - If you want to have TypeScript resolution for development, you can manually install the dependencies with `bun install` in the `assets/site` folder.

+# 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
+
+- [x] Axum Webserver
+  - [x] Health Check

+2. Refresh Token Background Job
+3. S3 Storage for Avatars
+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
+10. Name Restrictions & Flagging
+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.
