+
+A TBD-friendly pre-commit tool that enforces your team's Definition of Done (DoD) using an interactive checklist.
+
+This tool is designed for teams practicing Trunk-Based Development who want to automate their quality standards without the friction of a formal Pull Request process. It makes your team's DoD an active, developer-centric part of the commit workflow.
+
+The long-term goal is to integrate this functionality directly into the [`tbdflow`](https://github.com/cladam/tbdflow) CLI.
+
+# How It Works
+`check-commit` is a smart wrapper around `git commit`. Before it executes the commit, it looks for a `.dod.yml` file in your repository's root.
+
+If found, it presents an interactive checklist to the developer in the terminal. If the developer confirms the checklist, the tool proceeds to execute the `git commit` command with the original arguments.
+
+This creates a lightweight, non-obtrusive quality gate right at the moment of commit.
+
+## Configuration (`.dod.yml`)
+The checklist is configured in a `.dod.yml` file in your project's root. This makes your team's Definition of Done a version-controlled artifact that lives with your code.
+
+**Example** `.dod.yml`:
+```yaml
+# --- Optional Issue Tracker Integration ---
+# If true, the tool will require the --issue <ID> flag to be used,
+# ensuring all work is traceable.
+issue_reference_required: true
+
+# --- Interactive Checklist ---
+# This list is presented to the developer before every commit.
+checklist:
+  - "Code is clean, readable, and adheres to team coding standards."
+  - "All relevant automated tests (unit, integration) pass successfully."
+  - "New features or bug fixes are covered by appropriate new tests."
+  - "Security implications of this change have been considered."
+  - "Relevant documentation (code comments, READMEs, etc.) is updated."
+```
+
+## Getting Started (Development)
+This project is currently in the planning and early development phase.
+
+The initial proof-of-concept will be built in Rust.
+
+Roadmap:
+
+* Parse command-line arguments for `git commit`.
+* Read and parse the `.dod.yml` configuration file.
+* Implement the interactive checklist using a TUI library.
+* Execute `git commit` upon successful confirmation.
+* Integrate this logic into the `tbdflow commit` command.
