+# Build Scripts
+
+This directory contains scripts for building FreeSWITCH.
+
+## build-debs-native.sh
+Builds Debian packages for FreeSWITCH from git tree on supported Debian distributions.
+
+### TLDR: Example running from FreeSWITCH git root
+```bash
+scripts/packaging/fsget.sh pat_hFooBar
+scripts/packaging/build/build-debs-native.sh -b 999 -o /tmp/fsdebs/
+```
+
+### Prerequisites
+- Root access is recommended
+- Supported Debian system and architecture
+- FreeSWITCH git repository in the working directory
+- FreeSWITCH Debian repository configured (use `fsget.sh`)
+
+### Features
+- Automated dependency installation
+- FreeSWITCH Debian (source) package creation
+
+### Usage
+```bash
+./build-debs-native.sh -b BUILD_NUMBER -o OUTPUT_DIR [-w WORKING_DIR]
+```
+
+Required:
+- `-b`: Build number (part of package version)
+- `-o`: Output directory for packages
+
+Optional:
+- `-w`: Working directory (defaults to git root, needs to be git tree)
+
+### Output
+Generates `.deb`, `.dsc`, `.changes`, and `.tar.*` files in the output directory.
