-As you can see above, the result of the query gets added as Markdown below the query. Notice that the serialized version is surrounded by `<!-- SerializedQuery: <query> -->` and `<!-- SerializedQuery END -->`. Those allow the plugin to know what to replace. They should not be removed.
+As you can see above, the result of the query gets added as Markdown below the query. Notice that the serialized version is surrounded by `<!-- SerializedQuery: -->` and `<!-- SerializedQuery END -->` to delimit the serialized query.
 
 Whenever you update that note, the query will be executed and serialized, replacing the previous serialized version.
 
-WARNING: For now, the queries can only be put on a single line. Take a look at [this issue](https://github.com/dsebastien/obsidian-dataview-serializer/issues/12) for details/updates.
+Multiple line queries are now supported, here is an example:
+```
+<!-- QueryToSerialize: 
+TABLE
+	dateformat(release-date, "yyyy-MM-dd") AS "Release Date",
+	dateformat(started-date, "yyyy-MM-dd") AS "Started Date",
+	dateformat(finished-date, "yyyy-MM-dd") AS "Finished Date",
+	rating-out-of-ten + choice(recommended, " ❤️", "") AS "Note"
+FROM "Y. Content/Games" OR "03 - Resources/Games"
+WHERE file.name != "🏠 Games"
+SORT finished-date DESC
+-->
+```
 
 Note that a single note can include multiple queries. As soon as a file is modified, this plugin reads it and tries to locate queries to serialize. It starts by removing all the serialized queries, recognized by the `<!--SerializedQuery: END -->`line. Then, it serializes all the found queries to Markdown and saves the file again.
