 @sasjs/lint is used by the following products:
 
-  * [@sasjs/vscode-extension](https://github.com/sasjs/vscode-extension) - just download SASjs in the VSCode marketplace, and select view/problems in the menu bar.
-  * [@sasjs/cli](https://cli.sasjs.io/lint) - run `sasjs lint` to get a list of all files with their problems, along with line and column indexes.

+## SAS Lint Settings
 
-#### defaultHeader
+Each setting can have three states:
 
-This sets the default program header - applies when a SAS program does NOT begin with `/**`.  The default header is as follows:
+- OFF - usually by setting the value to `false` or 0. In this case, the rule won't be executed.
+- WARN - a warning is written to the log, but the return code will be 0
+- ERROR - an error is written to the log, and the return code is 1
+
+For more details, and the default state, see the description of each rule below. It is also possible to change whether a rule returns ERROR or WARN using the `severityLevels` object.
+
+Configuring a non-zero return code (ERROR) is helpful when running `sasjs lint` as part of a git pre-commit hook.  An example is available [here](https://github.com/sasjs/template_jobs/blob/main/.git-hooks/pre-commit).
+
+### allowedGremlins
+
+An array of hex codes that represents allowed gremlins (invisible / undesirable characters). To allow all gremlins, you can also set the `noGremlins` rule to `false`.  The full gremlin list is [here](https://github.com/sasjs/lint/blob/main/src/utils/gremlinCharacters.ts).
+
+Example:
+
+```json
+{
+  "noGremlins": true,
+  "allowedGremlins": ["0x0080", "0x3000"]
+}
+```
+
+### defaultHeader
+
+This isn't a rule, but a formatting setting, which applies to SAS program that do NOT begin with `/**`. It can be triggered by running `sasjs lint fix` in the SASjs CLI, or by hitting "save" when using the SASjs VS Code extension (with "formatOnSave" in place)

+The addition of the macro name in the `%mend` statement is optional, but can approve readability in large programs.

+### hasMacroParentheses
 
-#### hasMacroParentheses
-As per the example [here](https://github.com/sasjs/lint/issues/20), macros defined without parentheses cause problems if that macro is ever extended (it's not possible to reliably extend that macro without potentially breaking some code that has used the macro).  It's better to always define parentheses, even if they are not used.  This check will also throw a warning if there are spaces between the macro name and the opening parenthesis.

-#### ignoreList
-There may be specific files (or folders) that are not good candidates for linting.  Simply list them in this array and they will be ignored.  In addition, any files in the project `.gitignore` file will also be ignored.
+### hasRequiredMacroOptions
+
+This will require macros to have the options listed as "requiredMacroOptions." This is helpful if you want to ensure all macros are SECURE.
+
+- Default: false

+```json

+  "hasRequiredMacroOptions": true,

+### indentationMultiple
 
-#### indentationMultiple
 This will check each line to ensure that the count of leading spaces can be divided cleanly by this multiple.
 
-* Default:  2
-* Severity: WARNING
+- Default: 2
+- Severity: WARNING
 
-#### lowerCaseFileNames
-On *nix systems, it is imperative that autocall macros are in lowercase.  When sharing code between windows and *nix systems, the difference in case sensitivity can also be a cause of lost developer time.  For this reason, we recommend that sas filenames are always lowercase.
+### lineEndings
 
-* Default: true
-* Severity: WARNING
+This setting ensures the line endings in a file to conform the configured type. Possible values are `lf`, `crlf` and `off` (off means rule is set to be off). If the value is missing, null or undefined then the check would also be switched off (no default 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)

+- Default: true
+- Severity: WARNING
+
+### maxDataLineLength
+
+Datalines can be very wide, so to avoid the need to increase `maxLineLength` for the entire project, it is possible to raise the line length limit for the data records only. On a related note, as a developer, you should also be aware that code submitted in batch may have a default line length limit which is lower than you expect. See this [usage note](https://support.sas.com/kb/15/883.html) (and thanks to [sasutils for reminding us](https://github.com/sasjs/lint/issues/47#issuecomment-1064340104)).

+- cards

+- datalines

-#### noSpacesInFileNames
 The 'beef' we have with spaces in filenames is twofold:
 
-* Loss of the in-built ability to 'click' a filepath and have the file open automatically
-* The need to quote such filepaths in order to use them in CLI commands
+- Loss of the in-built ability to 'click' a filepath and have the file open automatically
+- The need to quote such filepaths in order to use them in CLI commands
 
-In addition, when such files are used in URLs, they are often padded with a messy "%20" type quotation.  And of course, for macros (where the macro should match the filename) then spaces are simply not valid.

-* Default:  true

+- Default: true

-#### noTabIndentation
-Whilst there are some arguments for using tabs to indent (such as the ability to set your own indentation width, and to reduce character count) there are many, many, many developers who think otherwise.  We're in that camp.  Sorry (not sorry).
+As an alternative (or in addition) to using a lint rule, you can also set the following in your `.gitignore` file to prevent files with spaces from being committed:
 
-* Default:  true
-* Severity: WARNING
+```
+# prevent files/folders with spaces
+**\ **
+```
 
-#### noTrailingSpaces
-This will highlight lines with trailing spaces.  Trailing spaces serve no useful purpose in a SAS program.
+### noTabs

+- Alias: noTabIndentation
+- Default: true
+- Severity: WARNING
 
-* `noTabs` -> does what it says on the tin
-* `noGremlins` -> identifies all invisible characters, other than spaces / tabs / line endings.  If you really need that bell character, use a hex literal!
-* `lineEndings` -> set a standard line ending, such as LF or CRLF
+### noTrailingSpaces
 
-## SAS Formatter
+This will highlight lines with trailing spaces. Trailing spaces serve no useful purpose in a SAS program.
+
+- Default: true
+- severity: WARNING
+
+
+## severityLevel
+
+This setting allows the default severity to be adjusted. This is helpful when running the lint in a pipeline or git hook. Simply list the rules you would like to adjust along with the desired setting ("warn" or "error"), eg as follows:
+
+```json
+{
+  "noTrailingSpaces": true,
+  "hasDoxygenHeader": true,
+  "maxLineLength": 100,
+  "severityLevel": {
+    "hasDoxygenHeader": "warn",
+    "maxLineLength": "error",
+    "noTrailingSpaces": "error"
+  }
+}
+```
+
+- "warn" - show warning in the log (doesn’t affect exit code)
+- "error" - show error in the log (exit code is 1 when triggered)
+
+# SAS Formatter
 
 A formatter will automatically apply rules when you hit SAVE, which can save a LOT of time.
 
 We've already implemented the following rules:
 
-* Add the macro name to the %mend statement
-* Add a doxygen header template if none exists
-* Remove trailing spaces
+- Add the macro name to the %mend statement

 We're looking to implement the following rules:
 
-* Change tabs to spaces
-* zap gremlins
-* fix line endings
+- Change tabs to spaces
+- zap gremlins
+- fix line endings
 
 We are also investigating some harder stuff, such as automatic indentation and code layout

-## SAS 9 Health check
+# Contributors ✨
 
-The SASjs Linter (and formatter) is a great way to de-risk and accelerate the delivery of SAS code into production environments.  However, code is just one part of a SAS estate.  If you are running SAS 9, you may be interested to know what 'gremlins' are lurking in your SAS 9 system.  Maybe you are preparing for a migration.  Maybe you are preparing to hand over the control of your environment.  Either way, an assessment of your existing system would put minds at rest and pro-actively identify trouble spots.
-
-The SAS 9 Health Check is a 'plug & play' product, that uses the [SAS 9 REST API](https://sas9api.io) to run hundreds of metadata and system checks to identify common problems.  The checks are non-invasive, and becuase it is a client app, there is NOTHING TO INSTALL on your SAS server.  We offer this assessment for a low fixed fee, and if you engage our (competitively priced) services to address the issues we highlight, then the assessment is free.
