```

More information on using `licensecheck` from the command line is available [here](documentation/user/README.md)

You can also import this into your own project and use any of the functions
in the DOCS

## Configuration Example

Configuration files are parsed in the following order: `pyproject.toml`, `setup.cfg`,
 `licensecheck.toml`, `licensecheck.json`, `~/licensecheck.toml`, `~/licensecheck.json`,

- ⚠ All config files are parsed, however configuration defined in previous files takes precedent

### Example 1: pyproject.toml

```toml

[tool.licensecheck]
license = "mit"               # Specify the project license explicitly
format = "simple"             # Output format (e.g., "json", "csv", etc.)
requirements_paths = []       # List of filenames to read from
groups = []                   # List of selected groups
extras = []                   # List of selected extras
file = ""                     # Output file (leave empty for stdout)
ignore_packages = []          # Packages/dependencies to ignore
fail_packages = []            # Packages/dependencies that cause failure
ignore_licenses = []          # Licenses to ignore
fail_licenses = []            # Licenses that cause failure
only_licenses = []            # Allowed licenses (all others will fail)
skip_dependencies = []        # Dependencies to skip (compatibility = True)
hide_output_parameters = []   # Parameters to hide from output
show_only_failing = false     # Show only incompatible/failing packages
pypi_api = "https://pypi.org" # Custom PyPI API endpoint
zero = false                  # Return non-zero exit code for incompatible licenses (for CI/CD)

```

### Example 2: licensecheck.json

```json
{
  "tool": {
    "licensecheck": {
      "extras": [],
      "fail_licenses": [],
      "fail_packages": [],

      "license": "mit",

      "pypi_api": "https://pypi.org",
      "requirements_paths": [],
      "show_only_failing": false,
      "skip_dependencies": [],
      "zero": false

## Documentation

A high-level overview of how the documentation is organized organized will help you know
where to look for certain things:

<!--
- [Tutorials](/documentation/tutorials) take you by the hand through a series of steps to get
  started using the software. Start here if you’re new.
-->
- The [Technical Reference](/documentation/reference) documents APIs and other aspects of the
  machinery. This documentation describes how to use the classes and functions at a lower level
  and assume that you have a good high-level understanding of the software.
<!--
- The [Help](/documentation/help) guide provides a starting point and outlines common issues that you
  may have.
