 For the most sensible markdown processing, it is as simple as getting your input
 into a byte slice and calling:
 
-``` go
-    output := blackfriday.Run(input)
+```go
+output := blackfriday.Run(input)
 ```
 
 Your input will be parsed and the output rendered with a set of most popular
 extensions enabled. If you want the most basic feature set, corresponding with
 the bare Markdown specification, use:
 
-``` go
-    output := blackfriday.Run(input, blackfriday.WithNoExtensions())
+```go
+output := blackfriday.Run(input, blackfriday.WithNoExtensions())
