-# Matmod: Matrix Model Generator for Implicative Connectives
+# Matmod: Verify Relevance Properties for Matrix Models with Implicative Connectives
 
-This repository is mostly an experiment to help
-me better understand matrix models.
+Interested in seeing which satisfiable models from [arranstewart/magic](https://github.com/arranstewart/magic) have the variable sharing property?
 
-You're likely better off using [arranstewart/magic](https://github.com/arranstewart/magic).
+(1) Generate satisfiable matrix models using `magic`.
+ - Use the `ugly` data format as the output
+ - Keep in mind not all logic features in magic are supported, check out the [GitHub issue tracker](https://github.com/Brandon-Rozek/matmod/issues) to see upcoming features or make your own requests
 
-We support output from magic using the ugly data format.
+(2) Run our tool! It will first attempt to parse all the matrices in the output file and then check for the variable sharing property one-by-one.
 
 ```
 python3 parse_magic.py < UGLY_FILE_FROM_MAGIC
 ```
+
+If you face any troubles, feel free to reach out. This tool also has capabilities to generate satisfiable models given a specification (see: R.py), however, it is much slower than magic so you're better off using that.
