 1. [Download and unzip](https://raw.githubusercontent.com/waf/dracula-cmd/master/dist/ColorTool.zip) ColorTool. The [source code](https://github.com/Microsoft/Terminal/tree/master/src/tools/ColorTool) is available from Microsoft.
 1. Open PowerShell, navigate to unzipped `ColorTool` directory, and run `install.cmd`.
 1. Right-click on the window titlebar and choose `Properties`, then on the `Font` tab choose Consolas. Click `OK` to save.
-    - Note that this step is required, even if your font is already set to Consolas, due to the way that the windows console saves its settings.

-1. Install the 1.0 version of posh-git.
-    - It's currently prerelease, so you'll need to install it with `Install-Module -Name posh-git -AllowPrerelease -Force`
-    - If you don't have an `-AllowPrerelease` flag, upgrade PowerShellGet with `Install-Module -Name PowerShellGet -Force` first.
-1. Ensure the latest version of PSReadLine (2.0 or later) is installed. It's installed by default in Windows 10, but you'll most likely [need to upgrade it](https://github.com/lzybkr/PSReadLine#user-content-upgrading).
-    - You can verify that 2.0 was installed by running `(Get-Module PSReadLine).Version`. If the installation does not appear to work, please see [this issue in PSReadLine](https://github.com/PowerShell/PowerShellGet/issues/318#issuecomment-418605987)
