 ## Orientation (v10.3.0+)
 
-In Mermaid, the default orientation is Left to Right. The branches are lined vertically.
+Mermaid supports two graph orientations: **Left-to-Right** (default) and **Top-to-Bottom**.
+
+You can set this with either `LR:` (for [**Left-to-Right**](#left-to-right-default-lr)) or `TB:` (for [**Top-to-Bottom**](#top-to-bottom-tb)) after `gitGraph`.
+
+### Left to Right (default, `LR:`)
+
+In Mermaid, the default orientation is for commits to run from left to right and for branches to be stacked on top of one another.
+
+However, you can set this explicitly with `LR:` after `gitGraph`.
 
 Usage example:
 
 ```mermaid-example
-    gitGraph
+    gitGraph LR:
        commit
        commit
        branch develop
        commit

+In `TB` (**Top-to-Bottom**) orientation, the commits run from top to bottom of the graph and branches are arranged side-by-side.
