 ### SAS Lint Settings
 
+#### defaultHeader
+
+This sets the default program header - applies when a SAS program does NOT begin with `/**`.  The default header is as follows:
+
+```sas
+/**
+  @file
+  @brief <Your brief here>
+  <h4> SAS Macros </h4>
+**/
+```
+
+The default header is automatically applied when running `sasjs lint fix` in the SASjs CLI, or by hitting "save" when using the SASjs VS Code extension.  If creating a new value, use `{lineEnding}` instead of `\n`, eg as follows:
+
+```json
+{
+  "defaultHeader": "/**{lineEnding}  @file{lineEnding}  @brief Our Company Brief{lineEnding}**/"
+}
+```
+
 #### noEncodedPasswords
 
 This will highlight any rows that contain a `{sas00X}` type password, or `{sasenc}`.  These passwords (especially 001 and 002) are NOT secure, and should NEVER be pushed to source control or saved to the filesystem without special permissions applied.

 #### maxLineLength
 Code becomes far more readable when line lengths are short.  The most compelling reason for short line lengths is to avoid the need to scroll when performing a side-by-side 'compare' between two files (eg as part of a GIT feature branch review).  A longer discussion on optimal code line length can be found [here](https://stackoverflow.com/questions/578059/studies-on-optimal-code-width)

 #### noNestedMacros
-Where macros are defined inside other macros, they are recompiled every time the outer macro is invoked.  Hence, it is widely considered inefficient, and bad practice, to nest macro definitions.
