 **GPU integrations for Dagger.jl**
 
-DaggerGPU.jl makes use of the `Dagger.Processor` infrastructure to dispatch Dagger kernels to NVIDIA, AMD, and Apple GPUs, via CUDA.jl, AMDGPU.jl, and Metal.jl respectively. Usage is simple: `add` or `dev` DaggerGPU.jl and CUDA.jl/AMDGPU.jl/Metal.jl appropriately, load it with `using DaggerGPU`, and add `DaggerGPU.CuArrayDeviceProc`/`DaggerGPU.ROCArrayProc`/`DaggerGPU.MtlArrayDeviceProc` to your scheduler or thunk options (see Dagger.jl documentation for details on how to do this).
+DaggerGPU.jl makes use of the `Dagger.Processor` infrastructure to dispatch Dagger kernels to NVIDIA, AMD, and Apple GPUs, via CUDA.jl, AMDGPU.jl, and Metal.jl respectively. Usage is simple: `add` or `dev` DaggerGPU.jl and CUDA.jl/AMDGPU.jl/Metal.jl appropriately, load it with `using DaggerGPU`, and add the appropriate GPU scope to the Dagger scope options, for example
+
+``` julia
+using CUDA, Dagger, DaggerGPU
+sc = Dagger.scope(cuda_gpu=1)
+
+# two large matrices
+A = rand(1000, 1000); B = rand(1000, 1000)
+# move them to gpu and multiply there
+A_gpu = Dagger.@spawn scope=sc CUDA.CuMatrix(A); B_gpu = Dagger.@spawn scope=sc CUDA.CuMatrix(B)
+C_gpu = Dagger.@spawn scope=sc A_gpu*B_gpu
+# move back to cpu to use there.
+C = Dagger.@spawn scope=sc Matrix(C_gpu) 
+```
+
+and similarly for `rocm_gpu` and `metal_gpu`.
 
 DaggerGPU.jl is still experimental, but we welcome GPU-owning users to try it out and report back on any issues or sharp edges that they encounter. When filing an issue about DaggerGPU.jl, please provide:
