-### Quick Start
 
-Setup Vortex environment:
+## Installation
-```
-$ 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:
+- Refer to the install instructions in [README](../README.md). 
+
+## Quick Start Scenarios
+
+Running Vortex simulators with different 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
