Power
The headset ships in a special mode that requires plugging into power first. Ensure your power adapter supports a minimum of 27W (45W recommended). After you have plugged it in, press the power button to turn it on, then follow the in headset instructions to get through the initial update. After the headset reboots, log into Steam.

Developer Mode
When you get your frame the first thing you will want to do is turn on
Developer Mode. This will allow you to
ssh,
adb, and
rdp into your headset. You will find this at
Steam Settings > System > Enable Developer Mode.

Then on the left, scroll down to the
Developer section, scroll toward the bottom of that page and click
Set User Password.

Beta
For the latest updates, it is recommended to opt into the beta versions of both the Steam client and SteamVR on PC.
For the Steam client, on your Desktop PC go to
Steam Settings > Interface > Client Beta Participation and select
Steam Beta Update. Steam will restart.
For SteamVR, go to its app page in your
Steam Library (still on your Desktop PC), click the gear icon, select
Properties > Betas > Beta Participation and select
SteamVR Beta Update.

Streaming
Plug the included wireless adapter into your PC (preferably a USB-3 port), launch SteamVR, and accept the prompt to install its driver.
Select Yes when prompted to pair, then
enter the code in your headset using the virtual keyboard.

If the prompt never appears, ensure you are opted into the Steam Beta Update. Or you may need to reboot your PC for the driver installation to take effect. If still not prompted, try restarting your headset, and ensure it is logged into the same Steam account.
Once paired, in headset point at the time in the dashboard bar to bring up
Quick Settings. You should see your PC’s name under
Other. Click your PC's name to connect. This will launch SteamVR on your PC, and your Steam Frame should now act just like any normal wired headset (sans wires).
Note: SteamVR will automatically reconnect to the last wireless headset it was launched with, so you can just launch SteamVR from the PC rather than needing to initiate from in-headset each time. If you still have a wired headset plugged into the PC, you may need to unplug that first. This "direct" mode is primarily intended for development. Normally, you'd just click Stream on games in your Steam Library in headset.
You can also stream over your home Wi-Fi, but that tends to be more congested and less reliable than the direct connection the wireless adapter affords.
Pairing Controllers
Your controllers should automatically pair when first turned on and are seen by the headset. To turn on your controllers, press the button with the Steam logo. If they do not turn on, verify the tab has been removed from the battery compartment. They will turn off automatically when not in use for a period of time.
If they do not show up in headset (while the dashboard is up) at this point, they may need to be manually paired. You can navigate the initial menus to log in using the Aux button, which is on the right hand side of headset just above the power button.
Once logged-in, on the dashboard side menu, click the VR Settings icon (HMD) on the left side of the screen. Under this menu, click
Controllers, then
Pair Controllers.
Put a controller in pairing mode by holding down the Steam button and the thin button at the top of the controller (either View or Menu) at the same time until the controller beeps. Then click the
Pair button to complete pairing. Repeat for the other controller.
Changing Your Device Name
If you are in an office full of other Steam Frames you will want to rename your device so you don't cause network collisions. Once you are logged in you can go to
Steam Settings > System > Hostname and change it to whatever you like. Then anywhere in these documents you see
frame as a hostname, just know to change it to whatever you have set here.
