-# QuickJS Android
-
-> Self-maintained QuickJS Android Bindings.
-
-## Usage
-
-1. Download the latest `.aar` archive from [release](https://github.com/shiqimei/quickjs-android/releases) page;
-2. In Android Studio: `File > New > New Module > Import .JAR/.AAR Package`, locate `.aar`, click `Finish`.
-
-```Java
-QuickJS quickJS = new QuickJS.Builder().build();
-try (JSRuntime runtime = quickJS.createJSRuntime()) {
-  try (JSContext context = runtime.createJSContext()) {
-    String script1 = "" +
-        "function fibonacci(n) {" +
-        "  if (n == 0 || n == 1) return n;" +
-        "  return fibonacci(n - 1) + fibonacci(n - 2);" +
-        "}";
-    // Evaluate a script without return value
-    context.evaluate(script1, "fibonacci.js");
-
-    String script2 = "fibonacci(10);";
-    // Evaluate a script with return value
-    int result = context.evaluate(script2, "fibonacci.js", int.class);
-    assertEquals(55, result);
-  }

-## Develop
+### Optimizations
 
-```bash
-git clone --recurse-submodules https://github.com/shiqimei/quickjs-android.git
+In addition to the relevant features and optimizations in the [TODO](https://github.com/openwebf/quickjs/blob/master/TODO) file, the more important optimizations are:
+
+- [x] Column number
+- [ ] Basic Debugger API
+- [x] Poly IC
+  - [x] Self Poly IC
+  - [x] Prototype Poly IC 
+- [x] Replace malloc To [mimalloc](https://github.com/microsoft/mimalloc)
+- [ ] Improve The Performance Of GC
+
+In our plan, we first complete the above optimizations and then gradually add the remaining parts.
+
+### Develop
+
+```shell
+> mkdir build
+> cd build
+> cmake .. && make -j4
 ```
 
-Open the folder `quickjs-android` in Android Studio.
+you can find `libquickjs.a` in lib folder and `qjs` / `qjsc` / `run-test262` in bin folder.
 
-## Benchmark
+#### Debug
 
-This is a non-serious benchmark. The purpose is to compare the performance of QuickJS and V8 on Android.
+Pass this argument to cmake enable debug log on release build.

-### Conclusion
 
-1. Even when operating in bytecode mode, QuickJS's evaluation time is notably higher than V8's, and this disparity intensifies as the JavaScript file size increases.
-2. QuickJS's initialization time is slightly lower than V8's, and this advantage is constant despite of file sizes.
