+Checking whitespace errors
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`whitespace`
+^^^^^^^^^^^^
+
+The `core.whitespace` configuration variable allows you to define what
+`diff` and `apply` should consider whitespace errors for all paths in
+the project (See gitlink:git-config[1]). This attribute gives you finer
+control per path.
+
+Set::
+
+ Notice all types of potential whitespace errors known to git.
+
+Unset::
+
+ Do not notice anything as error.
+
+Unspecified::
+
+ Use the value of `core.whitespace` configuration variable to
+ decide what to notice as error.
+
+String::
+
+ Specify a comma separate list of common whitespace problems to
+ notice in the same format as `core.whitespace` configuration
+ variable.
