 ## Stencil.Extension & swiftStencilEnvironment
 
 This framework also contains [helper methods for `Stencil.Extension` and `Stencil.Environment`](https://github.com/SwiftGen/StencilSwiftKit/blob/master/Sources/Environment.swift), to easily register all the tags and filters listed above on an existing `Stencil.Extension`, as well as to easily get a `Stencil.Environment` preconfigured with both those tags & filters `Extension` and the `StencilSwiftTemplate`.
+
+## Parameters
+
+This framework contains an additional parser, meant to parse a list of parameters from the CLI. For example, using [Commander](https://github.com/kylef/Commander), if you receive a `[String]` from a `VariadicOption<String>`, you can use the parser to convert it into a structured dictionary. For example:
+
+```swift
+["foo=1", "bar=2", "baz.qux=hello", "baz.items=a", "baz.items=b"]
+```
+
+will become
+
+```swift
+[
+  "foo": "1",
+  "bar": "2",
+  "baz": [
+    "qux": "hello",
+    "items": [
+      "a",
+      "b"
+    ]
+  ]
+]
