+# WSL
+
+[WSL](https://learn.microsoft.com/en-us/windows/wsl/) - short for Windows Subsystem for Linux - is
+a Tool of [Windows](/wiki/windows.md) that allows users and developers to run a
+[Linux](/wiki/linux.md) environment.
+
+## Setup
+
+WSL ist preinstalled on the newer Windows versions.
+Then the distribution to run may have to be [installed](#installing-a-distribution).
+
+## Usage
+
+### Installing a Distribution
+
+First make sure to update WSL.
+This can be done by running the following command.
+
+```powershell
+wsl --update
+```
+
+If the Microsoft Store is disabled on the system the command needs to be adapted.
+
+```powershell
+wsl --update --web-download
+```
+
+Then the distribution will be installed.
+First get the name of the distribution to be installed.
+This can be done by running the following command.
+
+```powershell
+wsl.exe -l -o
+```
+
+Afterwards install the distribution.
+`<Distribution Name>` is the name of the distribution obtained in the previous stepa.
+
+```powershell
+wsl.exe --install -d <Distribution Name>
+```
+
+On systems that have the Microsoft store disabled the distribution needs to be imported instead.
+For this a file system image of the distribution inside a tar archive is needed.
+These archives can be found on the websites of the distribution.
+For example Ubuntu file system images can be found
+[on their cloud image site](https://cloud-images.ubuntu.com/wsl/noble/current/).
+`<Distribution Name>` should be set to the name of the distribution.
+`<Install Location>` is the path where the systems files will be stored.
+`<Install TarFile>` is the path to the file obtained from the distributions website.
+
+```powershell
+wsl --import <Distribution Name> <Install Location> <Install TarFile>
+```
+
+Afterwards the default distribution may have to be set.
+Once again `<DistributionName>` is the name of the distribution to make the new default.
+
+```powershell
+wsl --setdefault <DistributionName>
+```
