+## Overview
+
+A [Git hook](https://git-scm.com/docs/githooks) is a program executed before a user commits code to a repository
+or pushes code to a remote location. A Git hook is generally used to run verifications
+and enforce requirements on the code before it is pushed to the remote branch.
+
+Datadog Code Analysis provides a Git hook to check for static analysis
+violations or secrets before code is pushed or committed. The Datadog Code Analysis Git hook
+checks the code from the latest commit and the default branch and surfaces
+any errors it detects.
+
+The Datadog Git hook warns developers before they push any code
+containing coding errors, vulnerabilities, or secrets. When you commit code with an
+error, a prompt like the following appears in the user terminal:
+

+
+## Setup
+
+1. Download the `datadog-git-hook` program from the release page or the [Datadog Static Analyzer
+releases](https://github.com/DataDog/datadog-static-analyzer/releases).
+2. Install the program on your computer.
+3. Add a `.git/hooks/pre-push` file in the repository with the script below. **Note:** The script assumes the `datadog-static-analyzer-git-hook` binary is in `/usr/local/bin/datadog-static-analyzer-git-hook`.
+
+```shell
+#!/bin/sh
+
+# Get the repo root path
+repo_path=$(git rev-parse --show-toplevel)
+
+# Make sure the user can provide some input
+exec < /dev/tty
+
+/usr/local/bin/datadog-static-analyzer-git-hook -r $repo_path --secrets --confirmation --default-branch <default-branch>
+
+if [ $? -eq 0 ]; then
+    echo "datadog-static-analyzer check passed"
+    exit 0
+else
+    echo "datadog-static-analyzer check failed"
+    exit 1
+fi
+```
+
+The program accepts the following parameters:
+
+ - `--confirmation`: Ask the user for confirmation to override the Git hook check
+ - `--default-branch`: Specify the name of the default branch.
+ - `--secrets`: Enable secrets detection (private beta).
+ - `--output <file>`: Export the findings found in the commit into a SARIF file.
