-## NOTE
-DOES NOT WORK ON MAC M1.
-Refer to the following issues:
-https://github.com/dart-lang/sdk/issues/48420
-
-## Reference
-As we develop the repro build process, reference https://github.com/signalapp/Signal-Android/tree/main/reproducible-builds and update this document.
-
-## Dev
-
-To inspect the container, uncomment the `CMD` line in the Dockerfile and run the following:
+## Usage
 
 ```bash
-docker build -t bullwallet .
-docker run -itd --name bbw bullwallet 
-docker exec -it bbw bash
-# inspect the container
+docker build -t bull-mobile .
+docker run --name bull-container bull-mobile
+docker cp bull-container:/app/build/app/outputs/apk/release/app-release.apk ./
 ```
-
-## TL;DR
-
-```bash
-git clone https://github.com/SatoshiPortal/bullbitcoin-mobile && cd bullbitcoin-mobile
-
-# Check out the release tag for the version you'd like to compare
-git checkout v[the version number]
-
-# Build the Docker image
-cd reproducible_builds
-docker build -t bullbitcoin-mobile .
-
-# Go back up to the root of the project
-cd ..
-
-# Build using the Docker environment
-docker run --rm -v $(pwd):/project -w /project bullbitcoin-mobile flutter build
-
-# Verify the APKs
