+# BYU C S 240 Code Style/Quality Checker
+This repository holds the source code for the "Code Quality Checker" for the BYU C S 240 class that is not part of the base checkstyle repository
+
+The code is based on [checkstyle](https://github.com/checkstyle/checkstyle) and includes the [checkstyle built-in checks](https://checkstyle.org/checks.html). Checkstyle also allows for [writing your own custom checks](https://checkstyle.org/writingchecks.html); most of the code in this repository is either a custom check or part of a test for a custom check.
+
+Checkstyle is based on the [Visitor Pattern](https://en.wikipedia.org/wiki/Visitor_pattern), often representing Java code in an [Abstract Syntax Tree (AST)](https://en.wikipedia.org/wiki/Abstract_syntax_tree). Because of this, any code must compile in order to be used as input for the checker. (Note to future TA's: if C S 236 still had you building a Datalog parser, an AST is somewhat similar to the list of tokens except it's a tree instead of a list of tokens)
+
+
+## Building
+This repository uses Maven for dependencies and building so you can build it with `mvn package` after which a jar will be in the `target` directory as `checkstyle-<version>.jar`, like `checkstyle-1.0.8.jar`.
+
+
+## Running
+`java -jar path/to/jar/checkstyle-<version>.jar -c <check file name>.xml <path to files/folders to check (can be multiple)`
+
+C S 240 Chess project running example (cs240_checks.xml is in the jar and usable from the jar, but you can substitute it if needed):
+
+`java -jar ./checkstyle-1.0.8.jar -c cs240_checks.xml ./client/ ./server/ ./shared/`
