-
-This repository contains the necessary files to compile the cryptography library used within [WrkzCoin](https://wrkzcoin.lol) as a standalone library that can be included in various other projects in a variety of development environments, including:
-
-* Node.js >= 6.x
-* C++
-* C# (via C++ shared library & P/Invoke)
-* Native Javascript
-* WASM
-
-## Javascript Library
-
-**Note:** This library is currently source-distributed. Build the Node.js native addon and WASM/JS binaries locally.
-
-### Dependencies
-
-* [Node.js](https://nodejs.org) >= +6.x LTS (or Node v11)
-
-#### Windows
-
-##### Prerequisites
-
-Read very careful if you want this to work right the first time.
-
-1) Open a *Windows Powershell* console as **Administrator**
-
-2) Run the command: `npm install -g windows-build-tools --vs2015`
-   ***This will take a while. Sit tight.***
-
-### Installation (from source)
+# WrkzCoin Crypto Library
+
+Standalone cryptography library for WrkzCoin with a focus on building `wrkzcoin-crypto-wasm.js` for multiple Linux distributions and platforms.
+
+## Build Targets
+
+- WASM JS bundle: `dist/wrkzcoin-crypto-wasm.js`
+- Native JS bundle: `dist/wrkzcoin-crypto.js`
+
+## Quick Build (WASM-focused)
 
 ```bash
 git clone -b master --single-branch https://github.com/wrkzcoin/wrkzcoin-crypto
 cd wrkzcoin-crypto
-npm install
-npm run build-typescript
-npm run build-native
+yarn install
+yarn build-typescript
+```
+
+Then build WASM/JS:
+
+```bash
+yarn build-native
+```
+
+If `yarn build-native` fails due to submodule/private repo fetch, use the manual build path below.
+
+## Manual WASM Build (No `build-native` script)
+
+Prerequisite: Emscripten tools available in `PATH` (`emcmake`, `emconfigure`, `emmake`).
+
+```bash
+mkdir -p dist
+mkdir -p jsbuild
+cd jsbuild
+
+emconfigure cmake .. -DNO_AES=1 -DARCH=default -DBUILD_WASM=1 -DBUILD_JS=0
+cmake --build . -- -j
+cp wrkzcoin-crypto-wasm.js ../dist/
+
+emconfigure cmake .. -DNO_AES=1 -DARCH=default -DBUILD_WASM=0 -DBUILD_JS=1
+cmake --build . -- -j
+cp wrkzcoin-crypto.js ../dist/
+```
+
+## Platform Prerequisites
+
+### Ubuntu / Debian
+
+```bash
+sudo apt-get update
+sudo apt-get install -y build-essential cmake git python3 make curl
 ```
-
-### Intialization
-
-#### TypeScript
-
-```javascript
+
+### Fedora / RHEL / Rocky
+
+```bash
+sudo dnf groupinstall -y "Development Tools"
+sudo dnf install -y cmake git python3 make curl
+```
+
+### Alpine
+
+```bash
+sudo apk add --no-cache build-base cmake git python3 make bash curl
+```
+
+### macOS
+
+```bash
+xcode-select --install
+brew install cmake git python make
+```
+
+### Windows
+
+Recommended: WSL2 (Ubuntu) and use Linux steps above.
+
+## TypeScript Usage (Local Build)
+
+```ts
 import { Crypto } from './dist';
-const WrkzCoinCrypto = new Crypto();
-```
-
-#### CommonJS
-
-```javascript
-const Crypto = require('./dist').Crypto
-const WrkzCoinCrypto = new Crypto()
-```
-
-#### Documentation
-
-You can find the full TypeScript/JS documentation for this library [here](https://crypto.wrkzcoin.dev).
-
-## C++ Library
-
-### How To Compile
-
-#### Build Optimization
-
-The CMake build system will, by default, create optimized *native* builds for your particular system type when you build the software. Using this method, the binaries created provide a better experience and all together faster performance.
-
-However, if you wish to create *portable* binaries that can be shared between systems, specify `-DARCH=default` in your CMake arguments during the build process. Note that *portable* binaries will have a noticable difference in performance than *native* binaries. For this reason, it is always best to build for your particuar system if possible.
-
-#### Linux
-
-##### Ubuntu, using GCC
-
-```bash
-sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y
-sudo apt-get update
-sudo apt-get install aptitude -y
-sudo aptitude install -y build-essential git cmake
-git clone -b master --single-branch https://github.com/wrkzcoin/wrkzcoin-crypto
-cd wrkzcoin-crypto
-mkdir build
-cd build
-cmake ..
-make -j
-```
-
-The static library will be built as `libwrkzcoin-crypto.a` in the build folder.
-
-##### Ubuntu, using Clang
-
-```bash
-sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y
-wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -
-```
-
-You need to modify the below command for your version of ubuntu - see https://apt.llvm.org/

-**Note:** If you have errors on this step about not being able to find the some libraries, you may need to update your cmake. Open 'Visual Studio Installer' and click 'Update'.
-
-`MSBuild wrkzcoin-crypto.sln /p:Configuration=Release /m`
-
-The following library files will be created in the `build/Release` folder:
