+Option Effects
+--------------
+There are two options for customizing how the fold text displays: `b:phpfold_text_right_lines` and `b:phpfold_text_percent`.
+
+When `b:phpfold_text_right_lines` is true, the number of lines folded along with the dashes that indicate the fold level are aligned on the right side of the screen.
+*`b:phpfold_text_right_lines = 0`:*
+```
+class ClassName
+{
++--  4 lines: public foo() {...}-------------------------------------------
++--  6 lines: public bar() {...}-------------------------------------------
++-- 12 lines: public baz() {...}-------------------------------------------
+}
+```
+
+*`b:phpfold_text_right_lines = 1`:*
+```
+class ClassName
+{
+    public foo() {...}----------------------------------------  4 lines +--
+    public bar() {...}----------------------------------------  6 lines +--
+    public baz() {...}---------------------------------------- 12 lines +--
+}
+```
+
+When `b:phpfold_text_percent` is true, the percentage of the total lines the fold represents is displayed alongside the line count:
+*`b:phpfold_text_right_lines = 0`:*
+```
+class ClassName
+{
++--  2 lines [ 8%]: public foo() {...}-------------------------------------
++--  8 lines [32%]: public bar() {...}-------------------------------------
++-- 12 lines [48%]: public baz() {...}-------------------------------------
+}
