+# Installing and running Windows Terminal
+
+> Note: Windows Terminal requires Windows 10 1903 (build 18362) or later
+
+## Microsoft Store [Recommended]
+
+Install the [Windows Terminal from the Microsoft Store][store-install-link].
+This allows you to always be on the latest version when we release new builds
+with automatic upgrades.
+
+This is our preferred method.
+
+## Other install methods
+
+### Via GitHub
+
+For users who are unable to install Windows Terminal from the Microsoft Store,
+released builds can be manually downloaded from our repository's [Releases
+page](https://github.com/microsoft/terminal/releases).
+
+Download the `Microsoft.WindowsTerminal_<versionNumber>.msixbundle` file from
+the **Assets** section. To install the app, you can simply double-click on the
+`.msixbundle` file, and the app installer should automatically run. If that
+fails for any reason, you can try the following command at a PowerShell prompt:
+
+```powershell
+# NOTE: If you are using PowerShell 7+, please run
+# Import-Module Appx -UseWindowsPowerShell
+# before using Add-AppxPackage.
+
+Add-AppxPackage Microsoft.WindowsTerminal_<versionNumber>.msixbundle
+```
+
+> Note: If you install Terminal manually:
+>
+> * Terminal will not auto-update when new builds are released so you will need
+>   to regularly install the latest Terminal release to receive all the latest
+>   fixes and improvements!
