+## What's OP Test Vectors?
+
+OP Test Vectors is a portable suite of standardized test fixtures used to test OP Stack component implementations.
+
+Test fixtures are static JSON files defined in the [fixtures](./fixtures) directory.
+
+Test fixtures can be easily generated using the [opt8n](./crates/opt8n) cli tool.
+
+### Development Status
+
+`op-test-vectors` is currently in active development, and is not yet ready for use in production.
+
+## Overview
+
+**`op-test-vectors`**
+
+- [`execution`](./crates/op-test-vectors/src/execution.rs): Rust types for the execution test fixtures.
+- [`derivation`](./crates/op-test-vectors/src/derivation.rs): Rust types for the derivation test fixtures.
+
+**`opt8n` Commands**
+
+- `repl`: Spins up a REPL that allows the user to send transactions to and generate a test fixture from those transactions.
+- `script`: Executes a forge script against an anvil instance and generates the test fixture.
+
+## Book
+
+The [book][book] contains an in-depth overview of the project, contributor guidelines, and tutorials for creating your own test fixtures as well as you own test runners.
+
+## Credits
+
+`op-test-vectors` is inspired by [ethereum/tests][eth-tests] and built by the collaboration between a number of teams and external contributors including [OP Labs][op-labs] and [Worldcoin engineers][worldcoin].
