+# Install SystemDS from Source
+
+This guide helps in the install and setup of SystemDS from source code.
+
+---
+
+- [1. Install on Windows](#1-install-on-windows)
+- [2. Install on Ubuntu 22.04](#2-install-on-ubuntu-2204)
+- [3. Install on macOS](#3-install-on-macos)
+- [4. Build the Project](#4-build-the-project)
+- [5. Run a Component Test](#5-run-a-component-test)
+- [6. Next Steps](#6-next-steps)
+
+Once the individual versions is set up skip to the common part of building the 
system.
+
+---
+
+# 1. Install on Windows
+
+First setup java and maven to compile the system note the java version is 17, 
we suggest using Java OpenJDK 17.
+
+- <https://openjdk.org/>
+- <https://maven.apache.org/download.cgi?.>
+
+Setup your environment variables with JAVA_HOME and MAVEN_HOME. Using these 
variables add the JAVA_HOME/bin and MAVEN_HOME/bin to the path environment 
variable. An example of setting it for java can be found here: 
<https://www.thewindowsclub.com/set-java_home-in-windows-10>
+
+To run the system we also have to setup some Hadoop and spark specific 
libraries. These can be found in the SystemDS repository. To add this, simply 
take out the files, or add 'src/test/config/hadoop_bin_windows/bin' to PATH. 
Just like for JAVA_HOME set a HADOOP_HOME to the environment variable without 
the bin part, and add the `%HADOOP_HOME%\bin` to path.
+
+On windows, cloning large repositories via GitHub Desktop may stall in some 
environments. If this happens, cloning via the Git command line is a reliable 
alternative.
+Example:
+```bash
+git clone https://github.com/apache/systemds.git 
+cd systemds
+```
+
+Finally if you want to run systemds from command line, add a SYSTEMDS_ROOT 
that points to the repository root, and add the bin folder to the path.
+
+To make the build go faster set the IDE or environment variables for java: 
'-Xmx16g -Xms16g -Xmn1600m'. Here set the memory to something close to max 
memory of the device you are using.
+
+To start editing the files remember to import the code style formatting into 
the IDE, to keep the changes of the files consistent.
+
+A suggested starting point would be to run some of the component tests from 
your IDE.
+
+# 2. Install on Ubuntu 22.04
+
+First setup java and maven to compile the system note that the java version is 
17.
+
+```bash
+sudo apt install openjdk-17-jdk
+sudo apt install maven
+```
+
+Verify the install with:
+```bash
+java -version
+mvn -version
+```
+
+This should return something like:
+```bash
+openjdk 17.0.11 2024-04-16
+OpenJDK Runtime Environment Temurin-17.0.11+9 (build 17.0.11+9)
+OpenJDK 64-Bit Server VM Temurin-17.0.11+9 (build 17.0.11+9, mixed mode, 
sharing)
+
+Apache Maven 3.9.9 (8e8579a9e76f7d015ee5ec7bfcdc97d260186937)
+Maven home: /home/usr/Programs/maven
+Java version: 17.0.11, vendor: Eclipse Adoptium, runtime: 
/home/usr/Programs/jdk-17.0.11+9
+Default locale: en_US, platform encoding: UTF-8
+OS name: "linux", version: "6.8.0-59-generic", arch: "amd64", family: "unix"
+```
+
+#### Testing
+
+R should be installed to run the test suite, since many tests are constructed 
to compare output with common R packages.
+One option to install this is to follow the guide on the following link: 
<https://linuxize.com/post/how-to-install-r-on-ubuntu-20-04/>
+
+At the time of writing the commands to install R 4.0.2 are:
+
+```bash
+sudo apt install dirmngr gnupg apt-transport-https ca-certificates 
software-properties-common
+sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 
E298A3A825C0D65DFD57CBB651716619E084DAB9
+sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu 
focal-cran40/'
+sudo apt install r-base
+```
+
+Optionally, you need to install the R dependencies for integration tests, like 
this:
+(use `sudo` mode if the script couldn't write to local R library)
+
+```bash
+Rscript ./src/test/scripts/installDependencies.R
+```

Review Comment:
   Verified source code and R installation on Ubuntu 24.04.
