 An implementation of the Algorand [ARC-4](https://arc.algorand.foundation/ARCs/arc-0004) ABI type system.
+
+> The scope of this module is intentionally minimal. If you wish to use a more
+> comprehensive library, consider [Algorand's Go SDK](https://github.com/algorand/go-algorand-sdk),
+> which uses this module internally.
+
+## Installation
+
+This module can be installed using the `go get` command.
+
+```sh
+go get github.com/algorand/avm-abi/abi
+```
