-## 🍪 Migrating from Cookiecutter
-
-> [!IMPORTANT]
-> This project was formerly known as `Poetry Cookiecutter` and was based on [Poetry](https://github.com/python-poetry/poetry) and [Cookiecutter](https://github.com/cookiecutter/cookiecutter). We will continue to support the original Cookiecutter-based template side by side with the new Copier-based template. However, we do encourage users to upgrade to the new Copier-based template by following the instructions below.
-
-To migrate a project from Cookiecutter to Copier, follow these steps:
-
-1. In your project repository, run:
-
-    ```sh
-    # Create a new branch
-    git checkout -b rescaffold
-
-    # Remove unnecessary files
-    rm -f .cruft.json poetry.lock
-
-    # Rescaffold the project without changing src/ and tests/
-    uvx copier copy --overwrite --exclude src/ --exclude tests/ gh:superlinear-ai/substrate .
-    ```
-
-2. Review the changes to `pyproject.toml` and reinsert your project's dependencies.
-3. Review the changes to `README.md` and reinsert your project's documentation.
-4. Commit and push all changes with:
-
-    ```sh
-    # Stage all changes
-    git add .
-
-    # Commit the staged changes
-    git commit -m "build: upgrade scaffolding"
-
-    # Push the committed changes
-    git push origin rescaffold
-    ```
-
-5. Create a PR from your branch, review it, and merge it!
