-### Recompiling the PTX
-
-It's likely that your GPU supports different CUDA capabilities than the precompiled `brightwire.ptx` in this repository. You can find what is your capability level [here](https://developer.nvidia.com/cuda-gpus). It's a number, ex. 3.0, 3.5, that you use for specifying `compute_XX` and `sm_XX` parameters.
-
-If you get an `ErrorNoBinaryForGPU` exception, that means you have to recompile. The instructions are [here](https://github.com/jdermody/brightwire/blob/master/BrightWire.CUDA.Net4.x64/cuda/readme.txt).

-Example command for NVIDIA GeForce GTX770M (CUDA 3.0)

-nvcc kernel.cu -use_fast_math -ptx -m 64 -arch compute_30 -code sm_30 -o kernel.ptx
-```

-## Linux Support
-
-### With CUDA
-
-Bright Wire can also work with CUDA on Mono. When you build your solution, you will need to extract `ConfigForLinux.zip` archive from [here](https://github.com/kunzmi/managedCuda/releases) to your output path.
-That way, CUDA won't look for `nvcuda` on Linux, but for libcuda shared object. You can even run on your Optimus enabled laptop (tested with GTX770M with Bumblebee) with `optirun mono [binary_name]`.
