-You will need to fullfil these dependecies:
-
-* Icarus Verilog (10.2+)
-* RV32I Toolchain
-
-Using apt, you can install Icarus Verilog:
-
-```bash
-sudo apt-get install iverilog
-```
-
-Next, you will need to build the RV32I toolchain. Firstly, export the installation path for the RV32I toolchain,
-
-```bash
-export GCC_PATH=<gcc-installation-path>
-```
-
-Then, run the following:
-
-```bash
-# packages needed:
-sudo apt-get install autoconf automake autotools-dev curl libmpc-dev \
- libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo \
- gperf libtool patchutils bc zlib1g-dev git libexpat1-dev

+# Local Installation (Linux)
+
+Instructions to install the dv setup locally (dockerless install).
+
+## You will need to fullfil these dependecies:
+
+* Icarus Verilog (10.2+)
+* RV32I Toolchain
+
+Using apt, you can install Icarus Verilog:
+
+```bash
+sudo apt-get install iverilog
+```
+
+Next, you will need to build the RV32I toolchain. Firstly, export the installation path for the RV32I toolchain,
+
+```bash
+export GCC_PATH=<gcc-installation-path>
+```
+
+Then, run the following:
+
+```bash
+# packages needed:
+sudo apt-get install autoconf automake autotools-dev curl libmpc-dev \
+ libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo \
+ gperf libtool patchutils bc zlib1g-dev git libexpat1-dev
+
+sudo mkdir $GCC_PATH
+sudo chown $USER $GCC_PATH
+
+git clone https://github.com/riscv/riscv-gnu-toolchain riscv-gnu-toolchain-rv32i
+cd riscv-gnu-toolchain-rv32i
+git checkout 411d134
+git submodule update --init --recursive
+
+mkdir build; cd build
+../configure --with-arch=rv32i --prefix=$GCC_PATH
+make -j$(nproc)
+```
+
+# Running Simulation
+
+You will need to export these environment variables:
+
+```bash
+export GCC_PATH=<gcc-installation-path>
+export PDK_PATH=<pdk-location/sky130A>
+```
+
+To run any simulation, you need to be on the top level or caravel_user_project.
+
+To run RTL simulation for one of the DV tests,
+
+```bash
+SIM=RTL make verify-<dv-test>
+```
+
+To run gate level simulation for one of the DV tests,
+
+```bash
+SIM=GL make verify-<dv-test>
+```
