-# TODO: README
+# StyleCheck
+
+`StyleCheck` provides the `splinter3d_style` CLI and a published `pre-commit` hook.
+
+## Local Development
+
+Use Poetry for local development so the CLI, test dependencies, and release tooling stay aligned with the project metadata.
+
+```bash
+poetry install
+poetry run splinter3d_style
+poetry run pytest
+```
+
+If you need to enter the virtual environment directly:
+
+```bash
+poetry shell
+splinter3d_style
+pytest
+```
+
+## Build And Test Locally
+
+Build the distribution files locally before creating a release:
+
+```bash
+poetry run python -m build
+ls dist/
+```
+
+Test the built package rather than the source tree:
+
+```bash
+pipx install ./dist/splinter3d_style-X.Y.Z-py3-none-any.whl
+splinter3d_style
+pipx uninstall splinter3d_style
+```
+
+You can also validate the source distribution or wheel with a throwaway virtualenv:
+
+```bash
+python3 -m venv .venv-build-test
+. .venv-build-test/bin/activate
+pip install ./dist/splinter3d_style-X.Y.Z-py3-none-any.whl
+splinter3d_style
+deactivate
+```
+
+`X.Y.Z` is a placeholder. Use the actual filename created in `dist/`, or install the first built wheel directly:
+
+```bash
+pipx install "$(ls dist/*.whl | head -n 1)"
+```
+
+## Install From A Release
+
+Install a published release artifact with `pipx`:
+
+```bash
+pipx install https://github.com/<owner>/StyleCheck/releases/download/vX.Y.Z/splinter3d_style-X.Y.Z-py3-none-any.whl
+splinter3d_style
+```
+
+## Use With pre-commit
+
+Add this repository and a release tag to your `.pre-commit-config.yaml`:
+
+```yaml
+repos:
+  - repo: https://github.com/<owner>/StyleCheck
+    rev: vX.Y.Z
+    hooks:
+      - id: splinter3d-style
+```
+
+Then install and run:
+
+```bash
+pre-commit install
+pre-commit run --all-files
+```
+
+## Release
+
+Releases are driven by pull requests and tags created by GitHub Actions:
+
+- Pull requests into `main` are only valid when they come from `dev` or `hotfix/*`.
+- When a pull request is merged into `dev`, CI creates a `vX.Y.Z-rc.N` tag.
+- When a pull request is merged into `main`, CI creates a `vX.Y.Z` tag.
+- Tag creation uses Commitizen to determine the next base version and defaults to `0.1.0` when no stable tag exists.
+- Every pushed release tag triggers the packaging workflow, which builds the distribution files and attaches them to a GitHub release.
+
+Protected GitHub environments can be applied to the `release-rc` and `release` jobs to gate prerelease and production publication independently.
