 prettifying, minifying, sanitizing, and/or validating JSON.  A
 `*ReEncoder` wraps an `io.Writer`, itself implementing `io.Writer`.
 The most common use of it will be something along the lines of
-

 An `*Encoder` handles encoding Go values into a JSON stream.
 `*Encoder` doesn't take much care in to making its output nice; so it
 is usually desirable to have the output stream of an `*Encoder` be a `*ReEncoder`; the most
 common use of it will be
-
-```go
-lowmemjson.NewEncoder(&lowmemjson.ReEncoder{
-	Out: out,

-```
+`lowmemjson.NewEncoder(lowmemjson.NewReEncoder(out, lowmemjson.ReEncoderConfig{…})).Encode(val)`.
 
 `*Encoder` and `*ReEncoder` both tend to make many small writes; if
 writes are syscalls, you may want to wrap their output in a
