+# Instructions
+
+Instructions on how to run list.
+
+## Windows
+
+There are two options. 
+
+### Run list.exe
+The easier option is to download list.zip, extract it and run list.exe.
+
+### Run list.jar
+To do this you first need to install the correct version of java (JDK). The program was developed and tested on [JDK Development Kit 21.0.2](https://www.oracle.com/java/technologies/downloads/#java21).
+If you already have another version of Java installed you might have to delete previous version before you install this version.
+
+Secondly, you may run list using `run.bat` which will run `list.jar` for you.
+
+## Linux
+### Run list.jar
+Similarly to running list.jar in Windows, you have to first make sure, that you have the appropriate version of Java installed. The program was developed and tested on [JDK Development Kit 21.0.2](https://www.oracle.com/java/technologies/downloads/#java21).
+If you already have another version of Java installed you might have to delete previous version before you install this version.
+
+Next, you may run list using `run.sh` which will run `list.jar` for you.
