+# Build from Source
+This guide provides step-by-step instructions for building the Stone prover and verifier from source on Linux and macOS devices.
+
+## Linux
+### Step 1: Install System Dependencies
+Install the necessary system libraries using your os package manager.
+```sh
+sudo apt-get update
+sudo apt-get install -y libtinfo5 libdw-dev libgmp3-dev git wget python3 python3-pip
+```
+
+### Step 2: Install Python Packages
+Install the required Python packages, including specific versions of sympy and cairo-lang, along with cpplint, pytest, and numpy.
+```sh
+pip install cpplint pytest numpy sympy==1.12.1 cairo-lang==0.12.0
+```
+
+### Step 3: Download and Set Up Bazelisk
+Install the Bazelisk binary to build the stone prover/verifier.
+```sh
+wget "https://github.com/bazelbuild/bazelisk/releases/download/v1.20.0/bazelisk-linux-amd64"
+chmod 755 "bazelisk-linux-amd64"
+sudo mv "bazelisk-linux-amd64" /usr/bin/bazelisk
+```
+
+### Step 4: Clone the Stone Prover Repository
+Clone the Stone prover repository from GitHub.
+```sh
+git clone https://github.com/baking-bad/stone-prover.git /tmp/stone-prover
+```
+
+### Step 5: Navigate to the Project Directory
+Change to the Stone prover project directory.
+```sh
+cd /tmp/stone-prover
+```
+
+### Step 6: Build the Project with Bazelisk
+Build the Stone prover and verifier using Bazelisk. Ensure the architecture is passed correctly.
+```sh
+bazelisk build //...
+```
+
+### Step 7: Run Tests with Bazelisk
+Run the tests to verify the build.
+```sh
+bazelisk test //...
+```
+
+### Step 8: Create Symbolic Links for Prover and Verifier
+To easily access the built prover and verifier binaries, create symbolic links in /usr/local/bin.
+```sh
+ln -s /tmp/stone-prover/build/bazelbin/src/starkware/main/cpu/cpu_air_prover /usr/local/bin/cpu_air_prover
+ln -s /tmp/stone-prover/build/bazelbin/src/starkware/main/cpu/cpu_air_verifier /usr/local/bin/cpu_air_verifier
+```
+
+### Step 9: Locating the built binaries
+```sh
+which cpu_air_prover
+which cpu_air_verifier
+# cpu_air_prover --help
+# cpu_air_verifier --help
+```
+
+## macOS
+### Step 1: Install Dependencies
+Homebrew is most likely already installed. If not:
+```sh
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+```
+
+To install the software, you'll need the following dependencies:
+```sh
+brew install git
+brew install gmp
+brew install [email protected]
+```
+
+### Step 2: Install Python Packages
+Install the required Python packages, including specific versions of sympy and cairo-lang, along with cpplint, pytest, and numpy.
+```sh
+python3 -m pip install --upgrade pip
+# --break-system-packages is specified to avoid issues related to PEP 668 https://peps.python.org/pep-0668/
+python3 -m pip install cpplint pytest numpy sympy==1.12.1 cairo-lang==0.12.0 --break-system-packages
+```
+
+### Step 3: Install Bazelisk
+Install the Bazelisk binary to build the stone prover/verifier.
+```sh
+brew install bazelisk
+```
+
+### Step 4: Clone the Stone Prover Repository
+Clone the Stone prover repository from GitHub.
+```sh
+git clone https://github.com/baking-bad/stone-prover.git /tmp/stone-prover
+```
+
+### Step 5: Navigate to the Project Directory
+Change to the Stone prover project directory.
+```sh
+cd /tmp/stone-prover
+```
+
+### Step 6: Build the Project with Bazelisk
+Build the Stone prover and verifier using Bazelisk. Ensure the architecture is passed correctly.
+```sh
+bazelisk build //...
+```
+
+### Step 7: Run Tests with Bazelisk
+Run the tests to verify the build.
+```sh
+bazelisk test //...
+```
+
+### Step 8: Create Symbolic Links for Prover and Verifier
+To easily access the built prover and verifier binaries, create symbolic links in /usr/local/bin.
+```sh
+ln -s /tmp/stone-prover/build/bazelbin/src/starkware/main/cpu/cpu_air_prover /usr/local/bin/cpu_air_prover
+ln -s /tmp/stone-prover/build/bazelbin/src/starkware/main/cpu/cpu_air_verifier /usr/local/bin/cpu_air_verifier
+```
+
+### Step 9: Locating the built binaries
+```sh
+which cpu_air_prover
+which cpu_air_verifier
+# cpu_air_prover --help
+# cpu_air_verifier --help
+```
