 This library is designed to execute JavaScript scripts and has the ability to register global functions and constants.
 It also allows you to configure security for executing scripts.
 
+## Quick Start
+
+```java
+import org.densy.scriptify.api.exception.ScriptException;
+import org.densy.scriptify.js.graalvm.script.JsScript;
+
+public class Main {
+    public static void main(String[] args) throws ScriptException {

+        Object result = script.evalOneShot("1 + 2 + 3");
+        System.out.println(result);
+    }
+}
+```
+
+For Rhino use `org.densy.scriptify.js.rhino.script.JsScript` instead.

+# Constants
+
+Constants expose named Java values to scripts.
+
+## Constant Interface
+
+```java
+org.densy.scriptify.api.script.constant.ScriptConstant
+```
+
+Create a constant:
+
+```java
+ScriptConstant constant = ScriptConstant.of("appName", "Scriptify");
+```
+
+Or implement it:
+
+```java
+public final class AppNameConstant implements ScriptConstant {
+    @Override
+    public String getName() {
+        return "appName";
+    }
+
+    @Override
+    public Object getValue() {
+        return "Scriptify";
+    }
+}
+```
+
+## Register Globally
+
+```java
+script.getConstantManager().register(ScriptConstant.of("appName", "Scriptify"));
+script.evalOneShot("appName");
+```
+
+Global constants are exported to the global module during compilation.
+
+## Export From a Module
+
+```java
+SimpleScriptInternalModule app = new SimpleScriptInternalModule("app");
+app.export(new ScriptConstantExport(ScriptConstant.of("name", "Scriptify")));
+script.getModuleManager().addModule(app);
+```
+
+```js
+import { name } from "app";
+name;
+```
+
+## Constant Manager
+
+`ScriptConstantManager` provides:
+
+```java
+Map<String, ScriptConstant> getConstants();
+ScriptConstant getConstant(String name);
+void register(ScriptConstant constant);
+void remove(String name);
+```
+
+Default implementation:
+
+```java
+org.densy.scriptify.core.script.constant.StandardConstantManager
+```
+
+## Built-In Core Constants
+
+| Constant | Value |
+| --- | --- |
+| `baseDir` | Current JVM working directory as an absolute string. |
+| `osName` | `System.getProperty("os.name")`. |
+
+These are exported by `StandardScriptModule`.
+
+## Deprecated Common Manager
+
+`CommonConstantManager` is deprecated. Prefer module exports.

+# Custom Runtime
+
+Scriptify can support additional scripting runtimes by implementing `Script<T>`.
+
+## Required Contract
+
+```java
+public final class MyScript implements Script<Object> {
+    private final ScriptSecurityManager securityManager = new StandardSecurityManager();
+    private final ScriptFunctionManager functionManager = new StandardFunctionManager();
+    private final ScriptConstantManager constantManager = new StandardConstantManager();
+    private final ScriptModuleManager moduleManager = createModuleManager();
+
+    @Override
+    public ScriptSecurityManager getSecurityManager() {
+        return securityManager;
+    }
+
+    @Override
+    public ScriptModuleManager getModuleManager() {
+        return moduleManager;
+    }
+
+    @Override
+    public ScriptFunctionManager getFunctionManager() {
+        return functionManager;
+    }
+
+    @Override
+    public ScriptConstantManager getConstantManager() {
+        return constantManager;
+    }
+
+    @Override
+    public CompiledScript<Object> compile(String source) throws ScriptException {
+        throw new UnsupportedOperationException();
+    }
+}
+```
+
+## Runtime Responsibilities
+
+A runtime implementation should:
+
+- create the engine context;
+- configure security before script execution;
+- expose global functions;
+- expose global constants;
+- expose internal modules;
+- load external modules;
+- apply `ScriptAccess.ALL` and `ScriptAccess.EXPLICIT`;
+- convert script values into Java values before invoking `ScriptFunction`;
+- convert Java return values back into runtime values;
+- wrap runtime failures in `ScriptException`;
+- close engine resources in `CompiledScript.close`.
+
+## Function Bridge
+
+Your runtime needs an engine-specific callable wrapper for `ScriptFunctionDefinition`.
+
+That wrapper should:
+
+- receive script arguments;
+- convert them to Java values;
+- find a matching `ScriptFunctionExecutor`;
+- call `executor.execute(script, args...)`;
+- convert the result back to the script engine.
+
+## Module Export Resolver
+
+Implement:
+
+```java
+ScriptModuleExportResolverFactory
+ScriptModuleExportResolver
+```
+
+The resolver maps Scriptify exports to runtime values:
+
+- `ScriptFunctionExport`;
+- `ScriptFunctionDefinitionExport`;
+- `ScriptConstantExport`;
+- `ScriptValueExport`;
+- custom `ScriptExport` implementations if you add them.
+
+Throw `ScriptModuleWrongContextException` if the factory receives a context object from another runtime.
+
+## Security Integration
+
+If the engine supports host class lookup restrictions, wire it to `ScriptSecurityManager.getExcludes()`.
+
+If the engine supports file system hooks, route file paths through:
+
+```java
+script.getSecurityManager().getPathAccessor()
+```
+
+If the engine exposes Java objects/classes, implement `ScriptAccess.EXPLICIT`.
