-ImportSorted [Sorting]
-Ensures that imports are sorted lexicographically.
-
-Imports should be sorted lexicographically to make it easier to find 
-specific imports. This rule ensures that imports are sorted in a 
-consistent manner. Specifically, the desired sort can be achieved
-with a GNU compliant `sort` and `LC_COLLATE=C`. No comments are
-permitted within an import statement.
+ImportPlacement [Clarity]
+Ensures that imports are placed between the version statement and any document items.
+
+All import statements should follow the WDL version declaration with one empty line between the version and the first import statement.
+```
+
+For example, this ordering triggers the rule:
+
+```wdl
+version 1.3
+
+workflow example {
+}
+
+import "example2.wdl"
+```
+
+Use this instead:
+
+```wdl
+version 1.3
+
+import "example2.wdl"
+
+workflow example {
+}
 ```
