 # NIST STEP to X3D Translator (STP2X3D)
-NIST STEP to X3D Translator is an open-source software that translates a STEP (ISO 10303) Part 21 file (.stp or .step) to an X3D (ISO/IEC 19776) file (.x3d) or X3DOM file (.html). The software is based on the [Open CASCADE STEP Processor](https://dev.opencascade.org/doc/overview/html/occt_user_guides__step.html) and written in C++.
+The NIST STEP to X3D Translator is an open-source software that translates a STEP (ISO 10303) Part 21 file (.stp or .step) to an X3D (ISO/IEC 19776) file (.x3d) or [X3DOM](https://www.x3dom.org/) file (.html). Developed at the National Institute of Standards and Technology (NIST), the software is based on the [Open CASCADE STEP Processor](https://dev.opencascade.org/doc/overview/html/occt_user_guides__step.html) and written in C++.  
 ## Prerequisites
 - [Open CASCADE Technology](https://www.opencascade.com/content/latest-release) (OCCT) 7.4.0 or higher (64 bit)
-  - You must rebuild the OCCT solution (vc14) to regenerate DLL files.
+  - You must build the OCCT solution (vc14) to (re)generate DLL files.
   - The complete set of DLL files required for STP2X3D to run is as follows.
     - freetype.dll, TKBO.dll, TKBRep.dll, TKCAF.dll, TKCDF.dll, TKernel.dll, TKG2d.dll, TKG3d.dll, TKGeomAlgo.dll, TKGeomBase.dll, TKHLR.dll, TKLCAF.dll.

   - Two environmental variables must be added as follows.
     - CSF_OCCTIncludePath: OCCTPath\inc
     - CSF_OCCTLibPath: OCCTPath\win64\vc14\lib
 ## Build the STEP to X3D Translator
-- Use [CMake](https://cmake.org/) to build the software.
+- Use [CMake](https://cmake.org/) 3.12.2 or higher to build the software.
   - vc14 must be selected for the generator.
 - You can also create a new project, include source files, and build the project in Visual Studio 2015.
   - Add $(CSF_OCCTIncludePath) to Additional Include Directories.
