-- adios github version or 1.11.0 .
+- adios github version or 1.11.0
 
 OpenFOAM
 - develop branch (or 1612).
 
+ThirdParty
+- develop branch (or 1612).

+
+Until this is fully integrated into OpenFOAM, the user should compile
+ADIOS using the ThirdParty `makeADIOS` script with the preferred ADIOS version.
+
+Subsequently, set `ADIOS_ARCH_PATH` accordingly. Eg,
+
+    adios_version=ADIOS-1.11.0
+    export ADIOS_ARCH_PATH=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER/$adios_version
+
+And optionally add it to the PATH
+
+    PATH=$ADIOS_ARCH_PATH/bin:$PATH
