+# Git Attributes
+
+GitLab supports defining custom [Git attributes][gitattributes] such as what
+files to treat as binary, and what language to use for syntax highlighting
+diffs.
+
+To define these attributes, create a file called `.gitattributes` in the root
+directory of your repository and push it to the default branch of your project.
+
+## Encoding Requirements
+
+The `.gitattributes` file _must_ be encoded in UTF-8 and _must not_ contain a
+Byte Order Mark. If a different encoding is used, the file's contents will be
+ignored.
+
+## Syntax Highlighting
+
+The `.gitattributes` file can be used to define which language to use when
+syntax highlighting files and diffs. See ["Syntax
+Highlighting"](highlighting.md) for more information.
