+# Layer Build & Docker Style Guide
+
+## General
+- This project focuses on building AWS Lambda Layers.
+- Consistency between the build environment (Docker) and the runtime environment (AWS Lambda) is critical.
+
+## Shell Scripting (Build Scripts)
+- Scripts like `build-multiarch.sh` and `package.sh` should be robust.
+- Use `set -e` to fail immediately if a build step fails.
+- Echo clear status messages to the console during long build processes.
+- Handle architecture differences (x86_64 vs arm64) explicitly.
+
+## Docker
+- Use Amazon Linux 2 or Amazon Linux 2023 base images to match Lambda runtimes.
+- Avoid installing unnecessary tools in the final layer output.
+- Ensure the output directory structure matches Lambda requirements exactly (`python/lib/pythonX.Y/site-packages`).
+
+## Python Dependencies
+- Use `requirements.txt` with pinned versions for reproducibility.
+- Separate build dependencies from runtime dependencies if necessary.
