-# REScala
+# This Repository
+
+This repository contains research software related to Programming Foundations for Distributed Systems at the [Software Technology Group](http://www.stg.tu-darmstadt.de/).
+
+The two most likely modules in this project you are interested in are the library for reactive programming, and the library for replicated data types, both are detailed below.
+
+All code in this repository is written in Scala and organized as a single [sbt](https://www.scala-sbt.org/) project containing multiple modules.
+
+The simplest way to get started is to install [coursier](https://get-coursier.io/docs/cli-installation) – a single binary called `cs` – and then run `cs launch sbt` in the project root directory. This provides you with the sbt shell, where you can type `compile` or `test` to ensure that everything is working correctly. If you get strange errors you may be using a too new/old java version, try `cs launch --jvm=21 sbt` to force the use of Java 21 (will be downloaded).
+
+Type `projects` into the sbt shell to get an overview of the available modules. Many modules have a JVM/JS/Native/Aggregate suffix, indicating that this module is cross compiled to different backends. You can select a specific module in the sbt shell by running, for example, `project reactivesJVM`. Then the `compile` or `test` commands will only happen in the selected module. See below for an overview of the modules.

+# Reactives / REScala
 
 REScala is a set of libraries for principled reactive programming,
 a programming paradigm that integrates the strong guarantees of functional reactive programming into object oriented programs,
 and is useful in many contexts such as traditional user interfaces, concurrent and distributed applications, web development, and server software.
