-### Installation
+   You can give `configure' initial values for configuration parameters
-First, start by cloning the repository:
+by setting variables in the command line or in the environment.  Here
+are examples:
 
-``` bash
+     ./configure CXX=clang++ CXXFLAGS="-std=c++11 -O3 -msse4" --enable-simd=SSE4
-git clone https://github.com/paboyle/Grid.git
-```
 
-Then enter the cloned directory and set up the build system:
+     ./configure CXX=clang++ CXXFLAGS="-std=c++11 -O3 -mavx" --enable-simd=AVX
 
-``` bash
+     ./configure CXX=clang++ CXXFLAGS="-std=c++11 -O3 -mavx2" --enable-simd=AVX2
-cd Grid
-./bootstrap.sh
-```
 
-Now you can execute the `configure` script to generate makefiles (here from a build directory):
+     ./configure CXX=icpc CXXFLAGS="-std=c++11 -O3 -mmic" --enable-simd=AVX512 --host=none
      
-``` bash
+Note: Before running configure it could be necessary to execute the script 
-mkdir build; cd build
-../configure --enable-precision=double --enable-simd=AVX --enable-comms=mpi-auto --prefix=<path>
-```
        
-where `--enable-precision=` set the default precision (`single` or `double`),
+       script/filelist
-`--enable-simd=` set the SIMD type (see possible values below), `--enable-
-comms=` set the protocol used for communications (`none`, `mpi`, `mpi-auto` or
-`shmem`), and `<path>` should be replaced by the prefix path where you want to
-install Grid. The `mpi-auto` communication option set `configure` to determine
-automatically how to link to MPI. Other options are available, use `configure
---help` to display them. Like with any other program using GNU autotool, the
-`CXX`, `CXXFLAGS`, `LDFLAGS`, ... environment variables can be modified to
-customise the build.
 
-Finally, you can build and install Grid:
 
-``` bash
-make; make install
-```
      
-To minimise the build time, only the tests at the root of the `tests` directory are built by default. If you want to build tests in the sub-directory `<subdir>` you can execute:
+For developers:
+Use reconfigure_script in the scripts/ directory to create the autotools environment 
 
-``` bash
-make -C tests/<subdir> tests
-```
-
-### Possible SIMD types
-
-The following options can be use with the `--enable-simd=` option to target different SIMD instruction sets:
-
-| String      | Description                            |
-| ----------- | -------------------------------------- |
-| `GEN`       | generic portable vector code           |
-| `SSE4`      | SSE 4.2 (128 bit)                      |
-| `AVX`       | AVX (256 bit)                          |
-| `AVXFMA4`   | AVX (256 bit) + FMA                    |
-| `AVX2`      | AVX 2 (256 bit)                        |
-| `AVX512`    | AVX 512 bit                            |
-| `AVX512MIC` | AVX 512 bit for Intel MIC architecture |
-| `ICMI`      | Intel ICMI instructions (512 bit)      |
