 Try a branch:
 
-1. `cd` into the `JabRef` directory: `cd c:\git-repositories\JabRef`
-2. Checkout out the pull request: `gh pr checkout 13111` - where `13111` is the PR number, in this case [pr#13111](https://github.com/JabRef/jabref/pull/13111).
-3. Compile and run JabRef: `gg.cmd gradle run :jabgui:run` (on Linux and macOS, you need to prefix it with `sh`: `gg.cmd gradle run :jabgui:run`). This will also download the necessary JDK and gradle distribution. On the first run, please give the system enough time to accommodate and wait until the JabRef window launches. Depending on your hardware, this may take minutes.

 Alternatives:
 
-1. You don't want to use `gg.cmd`: You have the project clone ready and have some Java JDK available: In the `JabRef` directory, execute `./gradlew run`.
-2. You don't want to use GitHub's `gh` tool: You can use the "usual" `git clone ...`, `git remote add ...`, `git fetch ...`, and `git checkout ...` commands to checkout a pull request from a fork.
