 8. After your modifications are done, push them to your forked repository. This can be done by executing the command `git add MYFILE` for every file you have modified, followed by `git commit -m 'your commit message here'` to commit the modifications and `git push` to push your modifications to GitHub.

 9. Create a Pull Request (PR) by going to your fork, <https://github.com/Your_Github_Handle/WebGoat> and click on the "New Pull Request" button. The target branch should typically be the Master branch. When submitting a PR, be sure to follow the checklist that is provided in the PR template. The checklist itself will be filled out by the reviewer.

 - New year's resolution: major refactoring of WebGoat to simplify the setup and improve building times.
 - Move away from multi-project setup:
-  - This has a huge performance benefit when building the application. Build time locally is now `Total time:  42.469 s` (depends on your local machine of course)
-  - No longer add Maven dependencies in several places
-  - H2 no longer needs to run as separate process, which solves the issue of WebWolf sharing and needing to configure the correct database connection.

 - More explicit paths in html files to reference `adoc` files, less magic.
 - Integrate WebWolf in WebGoat, the setup was way too complicated and needed configuration which could lead to mistakes and a not working application. This also simplifies the Docker configuration as there is only 1 Docker image.
