 ## Documentation
 
 At the heart of this module is the [HAR Format](http://www.softwareishard.com/blog/har-12-spec/#request) as the HTTP request description format, please review some of the sample JSON HAR Request objects in [test fixtures](/test/fixtures/requests), or read the [HAR Docs](http://www.softwareishard.com/blog/har-12-spec/#request) for more details.

 - The main `HTTPSnippet` export contains an `options` argument for an `harIsAlreadyEncoded` option for disabling [escaping](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent) of cookies and query strings in URLs.
   - We added this because all HARs that we interact with already have this data escaped and this option prevents them from being double encoded, thus corrupting the data.
 - Does not support the `insecureSkipVerify` option on `go:native`, `node:native`, `ruby:native`, and `shell:curl` as we don't want snippets generated for our users to bypass SSL certificate verification.
+- Includes a full plugin system, `#addClientPlugin`, for quick installation of a target client.
 - Node
   - `fetch`
     - Body payloads are treated as an object literal and wrapped within `JSON.stringify()`. We do this to keep those targets looking nicer with those kinds of payloads. This also applies to the JS `fetch` target as well.
