+### Quick Start
+
+Setup Vortex environment:
+```
+$ export RISCV_TOOLCHAIN_PATH=/opt/riscv-gnu-toolchain
+$ export PATH=:/opt/verilator/bin:$PATH
+$ export VERILATOR_ROOT=/opt/verilator
+```
+
+Test Vortex with different drivers and configurations:
+- Run basic driver test with rtlsim driver and Vortex config of 2 clusters, 2 cores, 2 warps, 4 threads
+
+    $ ./ci/blackbox.sh --clusters=2 --cores=2 --warps=2 --threads=4 --driver=rtlsim --app=basic
+- Run demo driver test with vlsim driver and Vortex config of 1 clusters, 4 cores, 4 warps, 2 threads
+
+    $ ./ci/blackbox.sh --clusters=1 --cores=4 --warps=4 --threads=2 --driver=vlsim --app=demo
+- Run dogfood driver test with simx driver and Vortex config of 4 cluster, 4 cores, 8 warps, 6 threads 
+
+    $ ./ci/blackbox.sh --clusters=4 --cores=4 --warps=8 --threads=6 --driver=simx --app=dogfood
