-# Specification References
-
-This directory contains specification reference tracking files managed by
-[ethspecify](https://github.com/jtraglia/ethspecify).
-
-## Installation
-
-Install `ethspecify` with the following command:
-
-```bash
-pipx install ethspecify
-```
-
-> [!NOTE]
-> You can run `ethspecify <cmd>` in the `specrefs` directory or
-> `ethspecify <cmd> --path=specrefs` from the project's root directory.
-
-## Maintenance
-
-When adding support for a new specification version, follow these steps:
-
-0. Change directory into the `specrefs` directory.
-1. Update the version in `.ethspecify.yml` configuration.
-2. Run `ethspecify process` to update/populate specrefs.
-3. Run `ethspecify check` to check specrefs.
-4. If there are errors, use the error message as a guide to fix the issue. If
-   there are new specrefs with empty sources, implement/locate each item and
-   update each specref source list. If you choose not to implement an item,
-   add an exception to the appropriate section the the `.ethspecify.yml`
-   configuration.
-5. Repeat steps 3 and 4 until `ethspecify check` passes.
-6. Run `git diff` to view updated specrefs. If an object/function/etc has
-   changed, make the necessary updates to the implementation.
-7. Lastly, in the project's root directory, run `act -j check-specrefs` to
-   ensure everything is correct.
