 ## Runtime Notes
 
-The pre-built Erlang runtime for Android ARM/ARM64/x86 is embedded in this example git repository. These native runtime files include Erlang OTP and the exqlite nif to use SQLite on the mobile. These runtimes are generated using the CI of the [Desktop Runtime](https://github.com/elixir-desktop/runtimes) repository.

-Because Erlang OTP has many native hooks for networking and cryptographics the Erlang version used to compile your App must match the pre-built binary release that is embedded. In this example that is Erlang OTP 25.0.4. This sample is shipping with a `.tool-versions` file that `asdf` will automatically use to automate this requirement.
