Pick the bit you need. Reading these in order is entirely optional.
| A command to copy | [CLI](cli.md) |
| Just the changes you need | [Filters](filters.md) |
| Finding the format or checking a file | [Detection and validation](detection.md) |
| A different way out | [Output formats](output-formats.md) |
| Something complaining at you | [Diagnostics](cli.md#diagnostics) |
| The Rust bits | [Library](library.md) |
| Making jq do the work | [JSON](json.md) |
| Your particular flavour of changelog | [Formats](formats/README.md) |
| Poking the code | [Development](development.md) |
The [examples](../examples/README.md) are real files you can feed to the CLI.
