-Use anonymous function:
+### Anonymous function
+
+Use an anonymous function as reducer which gets JSON and processes it:
 ```
-$ echo '{"foo": [{"bar": "value"}]}' | fx "x => x.foo[0].bar"
+$ echo '{"foo": [{"bar": "value"}]}' | fx 'x => x.foo[0].bar'
 "value"
 ```
 
+### This Binding
+
 If you don't pass anonymous function `param => ...`, code will be automatically transformed into anonymous function.
 And you can get access to JSON by `this` keyword:
 ```
-$ echo '{"foo": [{"bar": "value"}]}' | fx "this.foo[0].bar"
+$ echo '{"foo": [{"bar": "value"}]}' | fx 'this.foo[0].bar'
 "value"
 ```
 
+### Chain
+
 You can pass any number of anonymous functions for reducing JSON:
 ```
-$ echo '{"foo": [{"bar": "value"}]}' | fx "x => x.foo" "this[0]" "this.bar"
+$ echo '{"foo": [{"bar": "value"}]}' | fx 'x => x.foo' 'this[0]' 'this.bar'
 "value"
 ```
 
+### Generator
+
 If passed code contains `yield` keyword, [generator expression](https://github.com/sebmarkbage/ecmascript-generator-expression)
 will be used:
 ```
-$ curl ... | fx "for (let user of this) if (user.login.startsWith('a')) yield user"
+$ curl ... | fx 'for (let user of this) if (user.login.startsWith("a")) yield user'
 ```
