-## Build the docker image and run it
+# MPI-BugBench
+MPI-BugBench [[MBB24](#References)] is an benchmark suite to evaluate the classification quality of MPI correctness tools. It covers various error classes in MPI while incorporating a broad range of real-world MPI usage scenarios.
+
+
+## Preparation
+For simple reproduction, all workflows are executed within Docker containers.
+
+### Build the docker image and run it
 
 ```
 docker build -f Dockerfile.<parcoach|itac|must> -t mbb:latest .
 docker run -v `pwd`:/MBB -it mbb:latest bash
 ```
 
-## Generate the codes
-
+## Generating the codes
+MBB uses a generation infrastructure written in Python to generate all test codes and supports different test generation levels (for details, see our [paper](#References)).
+To generate the test cases for a given generation level (1-5) run the following commands:
 ```
 python3 MBB.py -c generate --level 2
 ```
-Or
+or
 ```
 cd /MBB
 tar -xf real_world_data.csv.tar.gz

-## To get stats on a tool
+## Analyzing results
 
+### CSV Results
 ```

-If you see an error like "Waiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 3509 (apt)"
-Try: apt clean
-And retry the command to run the tool: python3 MBI.py -x itac -c run
