 ## DRAMSys with gem5 SE Mode
 
 Install gem5 by following the instructions in the [gem5 documentation](https://www.gem5.org/documentation/general_docs/building). In order to allow a coupling without running into problems we recommend using the **develop** branch. Optionally, use the scripts from [gem5.TnT](https://github.com/tukl-msd/gem5.TnT) to install gem5, build it, get some benchmark programs and learn more about gem5.
