-### Best Used With Docker

 To evaluate the tests generated by the LLM, CoverUp must execute them.
 To minimize security concerns, including the risk of damage to your system, we recommend
 that you run CoverUp using [Docker](https://www.docker.com/).

+The graph shows CoverUp in comparison to the state-of-the-art [CodaMosa](https://www.carolemieux.com/codamosa_icse23.pdf),
+which improves upon the [Pynguin](https://github.com/se2p/pynguin) test generator by incorporating LLM queries.
+The bars show the difference in coverage percentage between CoverUp and CodaMosa for various Python modules;
+green bars, above 0, indicate that CoverUp achieved a higher coverage.
+As the graph shows, CoverUp achieves better coverage in almost every case.
+Both CoverUp and CodaMosa created tests "from scratch", that is, ignoring any existing test suite.

 ## Work In Progress
 Please enjoy this early release of CoverUp, and pardon any disruptions while we actively develop it.
