To create a README for your dfx-json-inspector crate, you can use the existing documentation comments in your code. Here's a draft README.md based on the information you provided:

# dfx-json-inspector

`dfx-json-inspector` is a command-line tool for analyzing `dfx.json` files in Internet Computer projects. It counts the number of canisters defined in the project and provides a summary of canister types.

## Features

- Parses and analyzes `dfx.json` files
- Counts total number of canisters
- Categorizes canisters by type
- Supports custom paths for `dfx.json` files

## Installation

Add this to your `Cargo.toml`:

```toml
[dependencies]
dfx-json-inspector = "0.1.0"

Usage

Run the tool from the command line:

$ dfx-json-inspector

Or specify a custom path:

$ dfx-json-inspector --path /path/to/project

API

The main functionality is provided by two key functions:

read_dfx_json(path: &str) -> Result<Value>

Reads and parses the dfx.json file from the given path.

analyze_canisters(json: &Value) -> Result<(usize, HashMap<String, u32>)>

Analyzes the canisters defined in the parsed dfx.json, returning the total count and a breakdown by type.
