+# Development Guide
+
+## Development Workflow
+
+### Initial Setup
+
+```bash
+# Install dependencies
+pixi install
+
+# Activate the dev environment (or use direnv for automatic activation)
+pixi shell -e dev
+```
+
+### Common Tasks
+
+```bash
+# pre-commit check
+pixi run pre-commit
+
+# Run tests
+pixi run test
+
+# Run all checks (format, lint, types, test)
+pixi run all
+```
+
+### Adding Dependencies
+
+```bash
+# Add a conda dependency
+pixi add <package-name>
+
+# Add a PyPI dependency
+pixi add --pypi <package-name>
+
+# Add a dev dependency
+pixi add --dev <package-name>
+```
+## Environment Setup
+
+The project uses `.envrc` for automatic environment activation via direnv.
+
+### What is `.envrc`?
+
+The `.envrc` file is used by direnv to automatically load environment variables when you enter the project directory.
+
+**Contents:**
+- `watch_file pixi.lock` - Tells direnv to reload when `pixi.lock` changes (e.g., after adding dependencies)
+- `eval "$(pixi shell-hook -e dev)"` - Activates the pixi dev environment, setting up the Python environment, PATH, and other variables
+
+**How it works:**
+- When you `cd` into the project directory, direnv automatically activates the pixi dev environment
+- When you leave, it deactivates
+- No need to manually run `pixi shell` or activate virtual environments
+
+**Setup required:**
+- Install `direnv` and add it to your shell (usually a one-time setup)
+- Run `direnv allow` once in the project directory to trust the `.envrc` file
+
+This keeps your development environment activated automatically as you work.
