+## Installing Preview Releases
+
+When installing a PowerShell Core Preview release for Linux via a Package Repository,
+the package name changes from `powershell` to `powershell-preview`.
+
+Installing via direct download does not change, other than the file name.
+
+Here is a table of the commands to install the stable and preview packages using the various package managers:
+
+|Distrobution(s)|Stable Command | Preview Command |
+|---------------|---------------|-----------------|
+| Ubuntu, Debian |`sudo apt-get install -y powershell`| `sudo apt-get install -y powershell-preview`|
+| CentOS, RedHat |`sudo yum install -y powershell` | `sudo yum install -y powershell-preview`|
+| OpenSUSE |`sudo zypper install powershell` | `sudo zypper install powershell-preview`|
+| Fedora   |`sudo dnf install -y powershell` | `sudo dnf install -y powershell-preview`|
+
