# Plugins

> Add security scanners, policy enforcement, and notification integrations to IaC deployments using env zero Plugins defined in your env0.yaml configuration file.

With env zero, you can keep your development organization's best practices for managing and executing Infrastructure as Code. Today we are happy to announce that we developed Plugins to make software development lifecycle tools and processes easier to integrate.

## Usage

> This is an opt-in feature
>
> To use a plugin in your env0.yaml file, you need to set its version to 2. If you wish to change an existing env0.yaml file to version 2, please follow the [migration guide](/guides/admin-guide/custom-flows/version-2-schema)

Using env zero plugins is done via your env0.yaml file. This is an example of how to use the [OPA plugin](https://github.com/env0/env0-opa-plugin):

```yaml theme={null}
version: 2
deploy:
  steps:
    terraformPlan:
      after:
        - name: OPA
          use: https://github.com/env0/env0-opa-plugin
          input:
            path: bundle-file-path
            flags: --fail --format=raw
            query: data.example.violation[x]
```

## Custom Plugins

You can also quickly create an env0 plugin of your own. To get started:

1. Open a new public Git repository.
2. Create an *env0.plugin.yaml* file that describes and configures your plugin's execution runtime and required inputs.
3. Use it in your *env0.yaml* file.
