-    The primary goals of this format is to allow a simple XML format 
-    that is mostly human readable. The generation and parsing of the 
-    various data types are done through the TypeConverter classes 
-    associated with the data types.
-

-        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
-        <comment>This is a comment</comment>
-    </data>
-                
-    There are any number of "resheader" rows that contain simple 
-    name/value pairs.
-    
-    Each data row contains a name, and value. The row also contains a 
-    type or mimetype. Type corresponds to a .NET class that support 
-    text/value conversion through the TypeConverter architecture. 
-    Classes that don't support this are serialized and stored with the 
-    mimetype set.
-    
-    The mimetype is used for serialized objects, and tells the 
-    ResXResourceReader how to depersist the object. This is currently not 
-    extensible. For a given mimetype the value must be set accordingly:
-    
-    Note - application/x-microsoft.net.object.binary.base64 is the format 
-    that the ResXResourceWriter will generate, however the reader can 
-    read any of the formats listed below.
-    
-    mimetype: application/x-microsoft.net.object.binary.base64
-    value   : The object must be serialized with 
-            : System.Serialization.Formatters.Binary.BinaryFormatter
-            : and then encoded with base64 encoding.

-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
-            : and then encoded with base64 encoding.

-    value   : The object must be serialized into a byte array

 # r2wars
 
-C# implementation for r2wars tournament
+![r2wars logo](csharp/resources/r2wars_logo_transparent.png?raw=true "r2wars")
 
-Tournament api from: https://github.com/otac0n/tournaments
+r2wars is a Core War-style tournament powered by radare2 and ESIL. Two
+assembly warriors share a 1 KiB arena and take turns executing instructions.
+Each warrior tries to corrupt its opponent until the opponent crashes, traps,
+or leaves the arena.
 
-## Description
+Warriors may target different CPU architectures while competing in the same
+address space.
 
-r2wars is a game similar to corewars, where 2 programs run on a
-shared memory space trying to catch each other in order to trash
-their code and make them crash.
+## Choose how to run it
 
-This game was initially developed by pancake as a PoC in here
+| Mode | Requirements | Execution | Best for |
+| --- | --- | --- | --- |
+| Docker | Docker with Compose | .NET and native radare2 in containers | Fastest local setup |
+| Native | .NET 10 and radare2 | Local .NET server and native radare2 | Development and full architecture support |
+| WebAssembly | Node.js/npm for building | Entirely inside the browser | Static hosting and serverless deployment |
 
-* https://github.com/radare/radare2-extras/tree/master/r2wars
+The WebAssembly implementation is an alternative execution path. It does not
+replace or change the existing .NET and Docker flows.
 
-You can find an explanation of the game in the first competition
-that happened during the 2nd r2con in 2017.
+## Quick start with Docker
 
-* https://www.youtube.com/watch?v=sB-i5yUatx4
+From the repository root:
 
-This repository contains an evolved implementation of the engine
-written in C# by SkUaTeR dropping the MFC requirement that was
-making it impossible to run outside Windows.
+```sh
+make start
+```
 
-The solution was to use an embedded webserver that provides a
-web interface using websockets to stream the process changes
-from the M
+Open <http://127.0.0.1:9664/>. The local `warriors/` directory is mounted
+read-only into the container.
 
-## Dependencies
+Useful commands:
 
-* Mono / .NET Runtime
-* radare2
+```sh
+make build   # build the Docker image
+make start   # start r2wars and its nginx frontend
+make stop    # stop the containers
+make clean   # stop and remove the r2wars image
+```
 
-On windows you need to have radare2.exe and rasm2.exe in the same
-directory as the r2wars.exe executable.
+The Docker image pins radare2 6.2.0 and verifies the official `amd64` or
+`arm64` release package before installing it.
 
-On Mac/Linux/BSD, r2wars will try to find them in the PATH.
+## Run natively
 
---pancake
+Install the .NET 10 SDK and radare2, then run:
+
+```sh
+dotnet run --project csharp/r2wars.csproj -- ../warriors
+```
+
+Open <http://127.0.0.1:9664/>.
+
+On Linux, macOS, and BSD, `radare2` and `rasm2` are loaded from `PATH`. On
+Windows, put `radare2.exe` and `rasm2.exe` in `PATH` or alongside the published
+r2wars application. The native interface uses the same bot manager and editor
+as the WebAssembly build; live previews are assembled by native `rasm2`.
+
+## WebAssembly version
+
+The browser version runs the tournament controller and radare2 ESIL locally in
+a Web Worker. It has no Kestrel or WebSocket connection, does not require
+Docker or .NET at runtime, and never uploads warrior source or tournament state.
+
+### Build and run locally
+
+```sh
+make wasm-build
+make wasm-run
+```
+
+Then open <http://127.0.0.1:5173/>. The production site is generated in
+`wasm/dist/`.
+
+The first build downloads the official radare2 6.2.0 WASI API module and
+verifies the checksums of both the release archive and extracted Wasm module.
+The module is about 44 MB before HTTP or ZIP compression.
+
+### Create a deployable ZIP
+
+```sh
+make wasm-dist
+```
+
+This creates `wasm/r2wars-wasm.zip`. The archive contains the complete static
+site with `index.html` at its root:
+
+```text
+index.html
+radare2.wasm
+assets/
+warriors/
+```
+
+Extract those files directly into a static server's document root. No
+application backend, .NET runtime, radare2 installation, or WebSocket proxy is
+needed. The paths are relative, so the site can also be hosted below a URL
+prefix.
+
+The server should deliver `.wasm` files as `application/wasm`. Opening
+`index.html` through `file://` is not supported because browsers restrict local
+Wasm and module loading; use any ordinary HTTP(S) static server instead.
+
+You can choose a different archive name when needed:
+
+```sh
+make wasm-dist WASM_ARCHIVE=my-r2wars-build.zip
+```
+
+### Shared web controls
+
+- The WebAssembly build initially loads three bundled bots. The .NET build
+  loads the configured warriors directory.
+- Open **Bots** while the tournament is not running to inspect the complete
+  roster, create or import bots, rename them, edit their assembly, or remove
+  them.
+- Bot edits are drafts. They do not modify a running or paused tournament and
+  are validated and loaded only when **Start new tournament** is selected.
+- Every filename or source edit is assembled immediately by the selected
+  engine—radare2 Wasm in the static build or native `rasm2` in the .NET build.
+  The editor shows a red or green result, the compiled size, and the complete
+  byte array; results over the 512-byte warrior limit are marked red.
+- Select **Choose warriors** to replace the draft roster with local `.asm`
+  files. Dropping `.asm` files onto the page adds or updates bots by filename.
+- Tournaments support run, pause, single-cycle stepping, bounded history,
+  standings, and downloadable reports.
+- In the WebAssembly build, tournament execution stays in a worker so the
+  interface remains responsive.
+
+### Browser architecture support
+
+The official radare2 6.2.0 WASI module contains x86, ARM, MIPS, RISC-V, and
+Game Boy support. It does not contain the 8051 plugin, so 8051 warriors require
+the native or Docker version for now.
+
+See [wasm/README.md](wasm/README.md) for implementation details and direct npm
+commands.
+
+## Writing warriors
+
+A tournament requires at least two non-empty `.asm` files. The architecture
+and bitness are encoded before the `.asm` extension:
+
+```text
+scanner.x86-32.asm
+hammer.arm-64.asm
+probe.mips-32.asm
+```
+
+Supported filename markers are:
+
+- `.x86-32.asm` and `.x86-64.asm`
+- `.arm-16.asm`, `.arm-32.asm`, and `.arm-64.asm`
+- `.mips-32.asm` and `.mips-64.asm`
+- `.riscv-32.asm` and `.riscv-64.asm`
+- `.gb.asm`
+- `.8051.asm` in the native and Docker versions
+
+Examples for several architectures are available in `examples/`. The default
+native and Docker tournament reads warriors from `warriors/`.
+
+## WebAssembly development commands
+
+Run these from the repository root:
+
+```sh
+make wasm-test   # test parsers and the engine against the real radare2 Wasm
+make wasm-build  # type-check and build wasm/dist/
+make wasm-run    # start the Vite development server
+make wasm-dist   # build and package wasm/r2wars-wasm.zip
+```
+
+The dedicated WebAssembly CI workflow runs the tests and production build, then
+uploads `wasm/dist/` as the `r2wars-wasm` artifact.
+
+## Background
+
+The original proof of concept lives in
+[radare2-extras](https://github.com/radare/radare2-extras/tree/master/r2wars).
+This repository evolved the engine into a portable C# implementation by
+SkUaTeR, replacing the original Windows-only MFC interface with a web UI.
