I'm on Windows 7, installed git and then posh-git (to run git from powershell), no errors. I'm able to enter git commands like 'git init' and 'git status' now from the powershell, and posh-git's tab completion works in my powershell, so I believe means posh-git was installed successfully.
However, according to posh-git documentation, my powershell prompt should now provide 'git status' info with colors (like [master] when my directory has a .git file), but it doesn't. I ran $GitPromptSettings (which I found on posh-git's github readme) but "EnablePromptStatus" is True, and I don't see any other options in the GitPromptSettings that it looks like I should change to enable the prompt status.
My current directory in powershell has a .git folder in it, from a 'git init' command I entered in powershell, so I can't figure out why posh-git's PromptStatus feature isn't reflected in my powershell prompt.
