+Notes for AVX512 Windows build
+==============================
+
+The visual studio version was updated from vs2015 to vs2022 to enable support of AVX512 Version
+1. Set the configuration in solution file to Release-AVX512 | x64
+2. Select the 'Generic POV-Ray > povbase' project and expand 'Backend Headers', then open the
+   file `build.h`(source/base/build.h) listed within it.In it replace with name
+   and email of person who builds the code in `BUILT_BY` flag and comment the #error directive (line 129)
+
+Steps for console build:
+1. In syspovconfig.h(windows/povconfig/syspovconfig.h) uncomment the #define _CONSOLE. (line 56)
+2. Build the solution file and in the vs2022/bin64 folder we can run the POVRAY examples with povconsole64-avx512.exe.
+```
+         General command example - povconsole64-avx512.exe +Ibenchmark.pov
+         Single worker thread - povconsole64-avx512.exe +WT1 benchmark.pov
+         Output image - benchmark.png
+```
+Results with the AVX512 version has been attached in the same folder.

+Notes for UNIX build
+====================
+
+Dependencies for unix build
+```
+   libboost-dev
+   libboost-date-time-dev
+   libboost-thread-dev
+   libz-dev
+   libpng-dev
+   libjpeg-dev
+   libtiff-dev
+   libopenexr-dev
+   pkg-config (if its already not there)
+```
+
+Steps :
+Generating configure and building the code :
+```
+   % cd unix/
+   % ./prebuild.sh
+   % cd ../
+   % ./configure COMPILED_BY="your name <email@address>"
+   % make
+```
+
+To build with icpc :
+```
+   % source /opt/intel/oneapi/setvars.sh
+   % cd unix/
+   % ./prebuild.sh
+   % cd ../
+   % ./configure COMPILED_BY="your name <email@address>" CXX=icpc
+   % make
+```
+
+Sample commands (inside the unix folder) :
+```
+         General command example - ./povray +Ibenchmark.pov
+         Single worker thread - ./povray +WT1 benchmark.pov
+         Output image - benchmark.png
+```
