Connect and interact with CloudFormation developers and\nexperts, find channels to discuss rain, the CloudFormation registry, StackSets,\ncfn-lint, Guard and more:\n\n[![Join our Discord](https://discordapp.com/api/guilds/981586120448020580/widget.png?style=banner3)](https://discord.gg/9zpd7TTRwq)\n\n## Key features\n\n* **Interactive deployments**: With `rain deploy`, rain packages your CloudFormation templates, prompts you for any parameters that have not yet been defined, shows you a summary of the changes that will be made, and then displays real-time updates as your stack is being deployed. Once finished, you get a summary of the outcome along with any error messages collected along the way - including errors messages for stacks that have been rolled back and no longer exist.\n\n* **Consistent formatting of CloudFormation templates**: Using `rain fmt`, you can format your CloudFormation templates to a consistent standard or reformat a template from JSON to YAML (or YAML to JSON if you prefer). Rain preserves your comments when using YAML and switches use of [intrinsic functions](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/intrinsic-function-reference.html) to use the short syntax where possible.\n\n* **Combin",
