If you know the request contains a body, and that it is

+within 8MB (for `body/1`) or 16KB (for `body_qs/1`) bytes,
+then you can read it directly with either `body/1` or `body_qs/1`.
+If you want to override the default size limits of `body/1`
+or `body_qs/1`, you can pass the maximum body length byte
+size as first parameter to `body/2` and `body_qs/2` or pass
+atom `infinity` to ignore size limits.
+If the request contains bigger body than allowed default sizes
+or supplied maximum body length, `body/1`, `body/2`, `body_qs/1`
+and `body_qs/2` will return `{error, badlength}`. If the request
+contains chunked body, `body/1`, `body/2`, `body_qs/1`
+and `body_qs/2` will return `{error, chunked}`.
+If you get either of the above two errors, you will want to
+handle the body of the request using `stream_body/1` and
+`skip_body/1`, with the streaming process optionally
+initialized using `init_stream/4` or `init_stream/5`.
