 ## GPU-accelerated Quantum ESPRESSO (QE-GPU)
 
-This is an open-source custom version of Quantum ESPRESSO v6.x with embedded GPU support based on CUDA FORTRAN. This product has been made possible thanks to the effort of the [NVIDIA](http://www.nvidia.com/page/home.html) HPC Software and Benchmarks Group. This version is maintained by [Filippo Spiga](https://github.com/fspiga) and hosted on University of Cambridge Research Software Engineering GitHub page. Partial support was provided by E4 Computer Engineering SpA via the European PRACE Pre-Commercial Procurement project (Phase 3).

 ### Requirements
 
-The feely available compiler suite [PGI Community Edition 17.4](http://www.pgroup.com/products/community.htm) is required to use QE-GPU. It containes CUDA SDK 8.0 and pre-built Open MPI for parallel execution (follow the [PGI Instalation Guide](http://www.pgroup.com/doc/pgiinstall174.pdf) how to install it). **No other compilers are supported**.

-You need data-centre grade NVIDIA TESLA Kepler (K20, K20, K40, K80) and NVIDIA TESLA Pascal (P100) compute GPUs. No other cards are supported. NVIDIA TESLA P100 is strongly recommend for its memory capacity and performance.

 ### Installation
 
-Installation process follow the same procedure as Quantum ESPRESSO suite:
+The installation process follows the same procedure as Quantum ESPRESSO suite:
 
 ```
 ./configure --enable-gpu
 make pw
 ```
 
-"make" alone prints a list of acceptable targets with GPU acceleration. Binaries go in "bin/". Additional configure options are made available to customize the building process:
