+- **SQLite 3.51.3** (amalgamation source in `sqlite3/jni/src/`)
 
-`sudo bash build.sh`
-`file */libsqlite3.so`
+## What this repository contains
+
+- Android `.so` libraries for:
+  - `arm64-v8a`
+  - `armeabi-v7a`
+  - `x86`
+  - `x86_64`
+- Windows `.dll` libraries for Unity Editor/Standalone:
+  - `x86`
+  - `x64`
+- WSA (Windows Store / UWP) `.dll` libraries:
+  - `ARM`
+  - `x86`
+  - `x64`
+
+Plugin output folders are under `Assets/Plugins/`.
+
+## Build Android libraries
+
+### Requirements
+
+- Android NDK with `ndk-build` available in `PATH`
+- Windows command prompt (script is a `.bat` file)
+
+### Command
+
+```bat
+build.bat
+```
+
+This compiles `sqlite3` via `ndk-build` and copies generated `libsqlite3.so` files into:
+
+- `Assets/Plugins/Android/arm64-v8a/`
+- `Assets/Plugins/Android/armeabi-v7a/`
+- `Assets/Plugins/Android/x86/`
+- `Assets/Plugins/Android/x86_64/`
+
+## Build Windows libraries
+
+### Requirements
+
+- Visual Studio Build Tools (script currently references:
+  `C:\Program Files\Microsoft Visual Studio\18\Community\VC\Auxiliary\Build\vcvarsall.bat`)
+
+### Command
+
+```bat
+build-windows.bat
+```
+
+This compiles `sqlite3.dll` for:
+
+- `Assets/Plugins/x86/sqlite3.dll`
+- `Assets/Plugins/x64/sqlite3.dll`
+- `Assets/Plugins/WSA/ARM/sqlite3.dll`
+
+## Source references
+
+- SQLite source files live in `sqlite3/jni/src/`.
+- Android NDK module file: `sqlite3/jni/Android.mk`.
+
+## Notes
+
+- This repository is focused on native plugin binaries for Unity.
+- Managed SQLite usage in Unity C# can vary by project setup (`Mono.Data.Sqlite`, P/Invoke wrappers, etc.).
