+Configuration
+-------------
+You can customize where Less `@import` statements load files from with `less_dir` (which defaults to `<source>/_less`).
+
+If you want to load imported files from another directory, add the following to `_config.yml`:
+
+    less:
+        less_dir: _my_custom_less_dir/
+
