 - The `Format` must be one that ClickHouse can use in `SELECT` queries and, if necessary, in `INSERTs`. For the full list of supported formats, see [Formats](../../../interfaces/formats.md#formats).
 
+    If this argument is not specified, ClickHouse detectes the format automatically from the suffix of the `URL` parameter. If the suffix of `URL` parameter does not match any supported formats, it fails to create table. For example, for engine expression `URL('http://localhost/test.json')`, `JSON` format is applied.
+
 - `CompressionMethod` indicates that whether the HTTP body should be compressed. If the compression is enabled, the HTTP packets sent by the URL engine contain 'Content-Encoding' header to indicate which compression method is used.
 
 To enable compression, please first make sure the remote HTTP endpoint indicated by the `URL` parameter supports corresponding compression algorithm.
@@ -27,6 +30,11 @@ The supported `CompressionMethod` should be one of following:
 - bz2
 - snappy
 - none
+- auto
+
+If `CompressionMethod` is not specified, it defaults to `auto`. This means ClickHouse detects compression method from the suffix of `URL` parameter automatically. If the suffix matches any of compression method listed above, corresponding compression is applied or there won't be any compression enabled.
+
+For example, for engine expression `URL('http://localhost/test.gzip')`, `gzip` compression method is applied, but for `URL('http://localhost/test.fr')`, no compression is enabled because the suffix `fr` does not match any compression methods above.
