+# Android Rust Builder
+
+This Docker image is designed for building Rust-based Android projects. It provides a pre-configured environment with all the necessary tools to compile Rust code for Android targets.
+
+## Features
+
+- Based on CircleCI's Android image (cimg/android:2025.04-ndk)
+- Rust nightly toolchain
+- Android targets for Rust:
+  - aarch64-linux-android
+  - armv7-linux-androideabi
+  - x86_64-linux-android
+  - i686-linux-android
+- Clang compiler
+- Mold linker (for faster linking)
+- Cargo-binstall for fast installation of binary dependencies
+- Cargo NDK for easy Android builds
+
+## Usage
