+This is a Microsoft Visual Studio solution that contains reference implementation of the TPM 2.0 Specification by TCG (https://trustedcomputinggroup.org/tpm-library-specification/).
+
+See TPMCmd/tpm/include/TpmTypes.h for the exact revision/date of the TPM 2.0 specification issue, which the given source tree snapshot corresponds to.
+
+Before building the solution:
+
+1) Create TPMCmd/lib folder and place a static OpenSSL library (libeay32.lib) there. Recommended version is 1.0.2d or higher.
+
+2) Create TPMCmd/OsslInclude/openssl folder and copy there the contents of the include/openssl folder of the OpenSSL source tree used to build the static library used on the step 1).
+
+3) Uncomment and update the definitions of the following macros in the TPMCmd/tpm/include/VendorString.h header:
+ - MANUFACTURER
+ - VENDOR_STRING_1
+ - FIRMWARE_V1 and FIRMWARE_V2
