 ### Building Binaries
 **Developers Only**
-##### Mac M1 Binaries
 
-👋This is not the section you are looking for.👋
-If you are trying to **build the binary** on macos with an M1 Mac and you are using pyenv to manage your python version. You'll probably need to reinstall a given python version using:
-```
-env PYTHON_CONFIGURE_OPTS="--enable-framework" pyenv install 3.10.3
+ethstaker-deposit uses `pyinstaller` to create binaries. The requirements are in `build_configs`. Look at `.circleci/config.yml` to see it in action.
+
+For example Linux, in your Python virtual environment:
+```sh
+export BUILD_FILE_NAME=ethstaker_deposit-cli-dev-linux
+pip install -r ./build_configs/linux/requirements.txt
+pyinstaller --distpath ./${BUILD_FILE_NAME} ./build_configs/linux/build.spec
 ```

+## Canonical Deposit Contract and Launchpad
+
+Ethstaker confirms the canonical Ethereum staking deposit contract addresses and launchpad URLs.
+Please be sure that your ETH is deposited only to this deposit contract address, depending on chain.
+
+Depositing to the wrong address **will** lose you your ETH.
