SlimeVR is an open source IMU based full body tracking system. Being open source it has Linux support and there are a few variants you can either buy or build yourself.
You can pre-order the official SlimeVR trackers from [their crowdsupply page](https://www.crowdsupply.com/slimevr/slimevr-full-body-tracker), but at the time of writing this if you order them right now you'd need to wait approximately 4 months for your orders to ship, due to the very high demand driven by low cost and good quality tracking compared to other solutions.

It's generally **highly recommended** to opt for the more expensive but higher quality [BNO085](https://shop.slimevr.dev/products/slimevr-imu-module-bno085) IMU module. This should offer the highest quality tracking with best precision and minimal drifting.
## Add and register the SteamVR driver

## Selecting your variant
There are currently two ways to use SlimeVR:
- Via SteamVR driver
- Directly via VRChat OSC (Open Sound Control)
## First method: SteamVR driver
Download the [SlimeVR driver for SteamVR](https://github.com/SlimeVR/SlimeVR-OpenVR-Driver/releases/latest/download/slimevr-openvr-driver-x64-linux.zip), extract it and place the `slimevr` folder in the `$HOME/.steam/steam/steamapps/common/SteamVR/drivers/` folder. This path may change depending on where your SteamVR install is located. To make sure you moved the right folder, make sure that the following path exists: `$HOME/.steam/steam/steamapps/common/SteamVR/drivers/slimevr/bin/linux64/driver_slimevr.so`.

```
## SlimeVR app
Now the only thing you have to do is restart the SlimeVR server.

**This method is only available in VRChat.**
It requires fewer steps to configure and allows the use of the full FOSS stack without using SteamVR. For now, it is less accurate due to OSC limitations. [More information here.](https://docs.slimevr.dev/server/osc-information.html)
- Step 1: Tick the checkbox in SlimeVR settings -> VRChat OSC Trackers -> Enable
![Configuration steps of VRChat OSC](vrchat_osc.png "Configuring VRChat OSC")
- Step 2: Start VRChat
- Step 3: Go to the radial menu, and enable OSC:
- Step 4: Calibrate your trackers via built-in SlimeVR configuration wizard (Mounting and body proportions)

- Step 5: Press the "Full Reset" button while standing straight

- Step 6: Go to VRChat settings and press "Calibrate FBT" in "Quick actions".

- Step 7: [T-pose](https://en.wikipedia.org/wiki/T-pose) yourself and submit your calibration via pressing triggers on both sides.
Done! From now on, you should be able to freely move your tracked limbs.
