+Follow these steps to get DRAMSys as part of gem5
+
+1. Go to ext/dramsys (this directory)
+2. Clone DRAMSys: 'git clone --recursive
g...@github.com:tukl-msd/DRAMSys.git DRAMSys'
+3. Change directory to DRAMSys: 'cd DRAMSys'
+4. Checkout the correct commit: 'git checkout -b gem5
09f6dcbb91351e6ee7cadfc7bc8b29d97625db8f'
+
+If you wish to run a simulation using the gem5 processor cores, make sure
to enable the storage mode in DRAMSys.
+This is done by setting the value of the "StoreMode" key to "Store" in the
base configuration file.
+Those configuration file can be found
in 'DRAMSys/library/resources/configs/simulator'.
