+# MD048 - Code fence style
+
+Tags: code
+
+Aliases: code-fence-style
+
+Parameters:
+
+* `style`: Code fence style (`string`, default `consistent`, values `backtick`/`consistent`/`tilde`)
+
+This rule is triggered when the symbols used in the document for fenced code
+blocks do not match the configured code fence style:
+
+````markdown
+```ruby
+# Fenced code
+```
+
+~~~ruby
+# Fenced code
+~~~
+````
+
+To fix this issue, use the configured code fence style throughout the
+document:
+
+````markdown
+```ruby
+# Fenced code
+```
+
+```ruby
+# Fenced code
+```
+````
+
+The configured list style can be a specific symbol to use (backtick, tilde), or
+can require that usage be consistent within the document.
+
+Rationale: Consistent formatting makes it easier to understand a document.
