There are a few other places we would like to direct you to for support, both from Microsoft and from the community.
The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.
For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality.
If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.
And always feel free to hit us up on Twitter @MxdRealityDev.
I already have a headset -- where to buy controllers?
I already purchased an HP Mixed Reality Headset (develop edition). I would like to buy a pair of controllers for it now as they were not available when I bought the headset. I cannot find them as a stand-alone purchase anywhere on the Microsoft Store or HP store. Where can you buy them alone?
