+Built on [Alloy][alloy], `op-alloy` connects applications to the OP Stack.
+
+
+## Usage
+
+To use `op-alloy`, add the crate as a dependency to a `Cargo.toml`.
+
+```toml
+op-alloy = "0.6"
+```
+
+## Development Status
+
+`op-alloy` is currently in active development, and is not yet ready for use in production.
+
+
+## Supported Rust Versions (MSRV)
+
+The current MSRV (minimum supported rust version) is 1.81.
+
+Unlike Alloy, op-alloy may use the latest stable release,
+to benefit from the latest features.
+
+The MSRV is not increased automatically, and will be updated
+only as part of a patch (pre-1.0) or minor (post-1.0) release.
+
+
+## Contributing
+
+op-alloy is built by open source contributors like you, thank you for improving the project!
+
+A [contributing guide][contributing] is available that sets guidelines for contributing.
+
+Pull requests will not be merged unless CI passes, so please ensure that your contribution follows the
+linting rules and passes clippy.
+
+
+## `no_std`
+
+op-alloy is intended to be `no_std` compatible, initially for use in [kona][kona].
+
+The following crates support `no_std`.
+Notice, provider crates do not support `no_std` compatibility.
+
+- [`op-alloy-consensus`][op-alloy-consensus]
+- [`op-alloy-genesis`][op-alloy-genesis]

+- [`op-alloy-rpc-types-engine`][op-alloy-rpc-types-engine]
+- [`op-alloy-rpc-types`][op-alloy-rpc-types]

+## Credits

+
+This would not be possible without the hard work from open source contributors. Thank you.
