+# SyntaxTree::JSON
+
+[![Build Status](https://github.com/ruby-syntax-tree/syntax_tree-json/actions/workflows/main.yml/badge.svg)](https://github.com/ruby-syntax-tree/syntax_tree-json/actions/workflows/main.yml)
+[![Gem Version](https://img.shields.io/gem/v/syntax_tree-json.svg)](https://rubygems.org/gems/syntax_tree-json)
+
+[Syntax Tree](https://github.com/ruby-syntax-tree/syntax_tree) support for JSON.
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+```ruby
+gem "syntax_tree-json"
+```
+
+And then execute:
+
+    $ bundle install
+
+Or install it yourself as:
+
+    $ gem install syntax_tree-json
+
+## Usage
+
+From code:
+
+```ruby
+require "syntax_tree/json"
+
+pp SyntaxTree::JSON.parse(source) # print out the AST
+puts SyntaxTree::JSON.format(source) # format the AST
+```
+
+From the CLI:
+
+```sh
+$ stree ast --plugins=json file.json
+(root children=[(tag name="span" value="Hello, world!")])
+```
+
+or
+
+```sh
+$ stree format --plugins=json file.json
+%span Hello, world!
+```
+
+or
+
+```sh
+$ stree write --plugins=json file.json
+file.json 1ms
+```
+
+## Development
+
+After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
+
+To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
