+# config-utils
+
+A CLI tool for capturing environment variables and Django settings in YAML format.
+
+## Features
+
+- **capture-env**: Capture all environment variables and export them to YAML
+- **capture-django-settings**: Capture Django project settings and export them to YAML
+
+## Installation
+
+### Using uv tool install (Recommended)
+
+Install the tool globally using `uv`:
+
+```bash
+uv tool install .
+```
+
+Or install from a remote location:
+
+```bash
+uv tool install config-utils
+```
+
+This will install the `config-utils` executable in your PATH.
+
+### Using uvx
+
+Run the tool directly without installation:
+
+```bash
+uvx --from . config-utils capture-env
+```
+
+### Using pip
+
+Install from the local directory:
+
+```bash
+pip install .
+```
+
+Or install in editable mode for development:
+
+```bash
+pip install -e .
+```
+
+
+## Usage
+
+### Capture Environment Variables
+
+Capture all environment variables to a YAML file:
+
+```bash
+config-utils capture-env
+```
+
+This will create `env_config.yaml` with all your environment variables.
+
+#### Options
+
+- `-o, --output PATH`: Specify output file path (default: `env_config.yaml`)
+- `-f, --format`: Output format, yaml or yml (default: `yaml`)
+
+#### Examples
+
+```bash
+# Capture to custom file
+config-utils capture-env -o my_env.yaml
+
+# Capture with yml extension
+config-utils capture-env -o config.yml -f yml
+```
+
+### Capture Django Settings
+
+Capture Django project settings to a YAML file using `python manage.py shell`:
+
+```bash
+# Run from your Django project directory
+cd /path/to/your/django/project
+config-utils capture-django-settings
+```
+
+This will create `django_settings.yaml` with all Django settings.
+
+#### Options
+
+- `-o, --output PATH`: Specify output file path (default: `django_settings.yaml`)
+- `-f, --format`: Output format, yaml or yml (default: `yaml`)
+- `-m, --manage-py PATH`: Path to manage.py (default: `manage.py`)
+- `-s, --settings`: Django settings module (e.g., `myproject.settings`)
+
+#### Examples
+
+```bash
+# From Django project root directory
+config-utils capture-django-settings
+
+# Specifying settings module via command line
+config-utils capture-django-settings -s myproject.settings
+
+# Custom output file
+config-utils capture-django-settings -o my_django_config.yaml
+
+# Specify manage.py path if not in current directory
+config-utils capture-django-settings -m /path/to/manage.py
+
+# Using DJANGO_SETTINGS_MODULE environment variable
+export DJANGO_SETTINGS_MODULE=myproject.settings
+config-utils capture-django-settings
+```
+
+**Note**: This command must be run from your Django project directory or you must specify the path to `manage.py` using the `--manage-py` option.
+
+### Using with uvx
+
+You can run the tool directly without installation:
+
+```bash
+# Capture environment variables
+uvx --from . config-utils capture-env
+
+# With options
+uvx --from . config-utils capture-env -o custom.yaml
+
+# Django settings (from Django project directory)
+cd /path/to/django/project
+uvx --from /path/to/config-utils config-utils capture-django-settings
+
+# Or specify manage.py path
+uvx --from /path/to/config-utils config-utils capture-django-settings -m /path/to/manage.py
+```
+
+## Requirements
+
+- Python >= 3.8
+- click >= 8.0.0
+- pyyaml >= 6.0
+
+**For Django settings capture**: The command uses `python manage.py shell`, so Django must be installed in your Django project's environment. The config-utils tool itself does not need Django as a dependency.
+
+## Development
+
+### Setup
+
+```bash
+# Clone or navigate to the project directory
+cd config-utils
+
+# Install in editable mode with development dependencies
+pip install -e .
+```
