 ## Compatibility
 
 TensorStream comes with a pure ruby and OpenCL implementation out of the box. The pure ruby implementation
 is known to work with most ruby implementations including TruffleRuby, JRuby as well as jit enabled versions of mri (ruby-2.6.0).
 
-OpenCL is supported only on mri implementations of ruby. This can be enabled by including the OpenCL evaluator (Make sure you have OpenCL drivers installed correctly on your system):
+OpenCL is supported only on mri implementations of ruby. This can be enabled by adding OpenCL evaluator gem (Make sure you have OpenCL drivers installed correctly on your system):

+and then (without bundler)

 ```ruby
-require 'tensor_stream/evaluator/opencl/opencl_evaluator'
+require 'tensor_stream-opencl'
 ```
 
 OpenCL is basically a requirement for deep learning and image processing tasks as the ruby implementation is too slow even with jit speedups using latest ruby implementations.
 
 OpenCL kernels used by tensorstream can be found at tensor_stream/lib/evaluator/opencl/kernels. These are non specific and should work with any device that supports OpenCL including intel GPUs and CPUs, as well as GPUs from Nvidia and AMD.

 For OpenCL support, make sure that the required OpenCL drivers for your hardware are correctly installed on your system.
 Also OpenCL only supports ruby-mri at the moment.
 
 Also include the following gem in your project:

-To use the opencl evaluator instead of the ruby evaluator simply add require it.

 Adding the OpenCL evaluator should expose additional devices available to tensor_stream
