+# MD046 - Code block style
+
+Tags: code
+
+Aliases: code-block-style
+
+Parameters:
+
+* `style`: Block style (`string`, default `consistent`, values `consistent`/`fenced`/`indented`)
+
+This rule is triggered when unwanted or different code block styles are used in
+the same document.
+
+In the default configuration this rule reports a violation for the following document:
+
+<!-- markdownlint-disable code-block-style -->
+
+    Some text.
+
+        # Indented code
+
+    More text.
+
+    ```ruby
+    # Fenced code
+    ```
+
+    More text.
+
+<!-- markdownlint-restore -->
+
+To fix violations of this rule, use a consistent style (either indenting or code
+fences).
+
+The specified style can be specific (`fenced`, `indented`) or simply require
+that usage be consistent within the document (`consistent`).
+
+Rationale: Consistent formatting makes it easier to understand a document.
