+## Rowhammer Tester Target Configuration
+
 The following instructions explain how to set up the board.
 
+Connect the board USB-C `J3` and Ethernet `J6` via cable to your computer, plug the board into the power socket `J7` and turn it on using power switch `SW5`. Then configure the network. The board's IP address will be `192.168.100.50` (so you could e.g. use `192.168.100.2/24`). The `IP_ADDRESS` environment variable can be used to modify the board's address.
+Next, generate the FPGA bitstream:
+
+```sh
+export TARGET=sodimm_ddr5_tester
+make build TARGET_ARGS="--l2-size 256 --build --iodelay-clk-freq 400e6 --bios-lto --rw-bios --no-sdram-hw-test"
+```
+
+```{note}
+--l2-size 256 sets L2 cache size to 256 bytes
+
+--no-sdram-hw-test disables hw accelerated memory test
+```
+
+```{note}
+By typing `make` (without `build`) LiteX will generate build files without invoking Vivado.
+```
+
+The results will be located in: `build/sodimm_ddr5_tester/gateware/antmicro_sodimm_ddr5_tester.bit`. To upload it, use:
+
+```sh
+export TARGET=sodimm_ddr5_tester
+make upload
+```
+
+To save bitstream in flash memory, use:
+
+```sh
+export TARGET=sodimm_ddr5_tester
+make flash
+```
+
 ```{warning}
-There is a `SW1` `MODE` selector on the right close to FPGA.
-The default configuration mode is set to ```JTAG```. If the bitstream needs to be loaded from the Flash memory, select ```Master SPI``` mode.
