+        --
+        The SQL console is a page where you can write and execute custom SQL
+        queries on the underlying database that your Perfin profile is using.
+        --
+        Unless otherwise noted, Perfin uses the [H2 Database](https://www.h2database.com/html/main.html),
+        but for most common purposes, the SQL query syntax is identical to other
+        common dialects.
+        --
+        Simply write your queries in the upper text area, press **Execute**, and
+        view the results in the output area below. When running multiple queries,
+        be sure to end each with a semicolon (`;`). Results are shown as comma
+        separated columns of text, starting with an initial row for the column
+        names.
+
+        # Comments #
+        Prepend your query with `#` or `//` to exclude it from execution. Each
+        comment character disables all query syntax up until the next semicolon,
+        (`;`).
+
+        # Saved Queries #
+        Click on the **Save Query** button to save the contents of the editor
+        into a *saved query*, which can then be loaded again at any time. You
+        can find the saved query files under `/content/saved-queries`, in your
+        profile's directory.
