 Laughing-Train is a code refactoring tool using [Spoon](https://github.com/INRIA/spoon) and static analyzers to refactor Java code.
 This includes the analysis of the code, the refactoring of the code and the generation of pull requests on GitHub.
-For this, we leverage many existing tools and libraries, like quarkus, Hub4J, spoon, Qodana.
+We analyze projects with qodana, a static code analyzer from JetBrains, and use the results to refactor the code.
+The refactoring is done with Spoon, a Java parser and transformer. The results are then pushed to GitHub as pull requests.
+For GitHub integration, we use the GitHub API and the GitHub CLI.
+The website is built with react and the backend is written with Quarkus.

 ### Why use Qodana?
 
-I use vscode as IDE, but I'm impressed by the tooling JetBrains provides. Qodana seems way ahead of the competition and is a impressive tool to use. There exists abstraction for further analyzers, but I'm uncertain if I will ever implement them.

 ### Why not help an existing tool?
 Existing tools have either pretty long release schedules, are not using spoon, or I see no value in the tool. Here I can merge, break and change things as I like without too much hassle.
