 See the definition of the `SPEC_VERSION`, `SPEC_YEAR` and `SPEC_DAY_OF_YEAR` values in the [TpmTypes.h](TPMCmd/tpm/include/TpmTypes.h) header for the exact revision/date of the TPM 2.0 specification, which the given source tree snapshot corresponds to.
 
-## Visual Studio build ##
+The reference implementation can be directly used via the [TPM 2.0 simulator](TPMCmd/Simulator) that emulates a TPM 2.0 device and can be accessed via a custom TCP based protocol. The simplest way to work with the simulator is to use a [TSS library](https://github.com/Microsoft/TSS.MSR) for the programming language of your choice - C#/.Net, C++, Java, Python, JavaScript/Node.js are currently supported. The C language TSS implementing the TCG's TSS API specifiaction is available [here](https://github.com/tpm2-software/tpm2-tss).
 
-Before building the Visual Studio solution:
+## Windows build ##
 
-1. Uncomment and update the definitions of the following macros in the [VendorString.h](TPMCmd/tpm/include/VendorString.h) header:
- - MANUFACTURER
- - VENDOR_STRING_1
- - FIRMWARE_V1 and FIRMWARE_V2

-2. Setup the underlying cryptographic library:

-### OpenSSL library ###

-1. Create `TPMCmd/lib` folder and place a static OpenSSL library (`libcrypto.lib`) built for the `x86` architecture there. For the `x64` architecture use the `TPMCmd/lib/x64` folder.

-    The static libs can be either static libraries proper, or import libraries accompanying the corresponding DLLs. In the latter case you'll need to ensure that ther is a matching copy of the OpenSSL DLL in the standard Windows search path, so that it is available when you run the simulator executable (e.g. copy it into the same folder where `simulator.exe` is located).

-3. Build the solution with either Debug or Release as the active configuration.
+      If you enable SM{2,3,4} algorithms in `TpmProfile.h`, the build may fail because of missing `SM{2,3,4}.h` headers. In this case you will need to manually copy them over from OpenSSL’s `include/crypt` folder.

 ## Linux build
 
 Follows the common `./bootstrap && ./configure && make` convention.
 
 Note that autotools scripts require the following prerequisite packages: `autoconf-archive`, `pkg-config`, and sometimes `build-essential` and `automake`. Their absence is not automatically detected. The build also needs `gcc` and `libssl-dev` packages.
