+# SOF Helper Scripts
+
+This folder contains a lot of useful scripts that can speed up development for routine tasks or simplify execution of complex tasks.
+
+## Build Scripts
+
+SOF has several build targets depending on whether you are building firmware, tooling, documentation or topologies. This directory has a helper for each.
+
+### Firmware
+
+Firmware can either be built using west command directly or by the xtensa-build-zephyr.py script. This script wraps up the west commands and can build using either the Zephyr SDK compiler or the Cadence xtensa compiler for xtensa targets.
+
+Please run the script with --help to see all options.
+
+E.g to build SOF for Intel Pantherlake:
+
+1) Enable the python virtual environment for west. This should be in your SOF workspace installation direction. Default is ```~/work/sof``` (only needs run once).
+```bash
+source ~/work/sof/.venv/bin/activate
+```
+2) Now run the build script. *Note: most build errors are a result of ingredients being out of sync with the west manifest. Please run ```west update``` and rebuild before fixing/reporting build errors.*
+```bash
+./scripts/xtensa-build-zephyr.py -p ptl
+```
+
+### Testbench
+
+Testbench is a host application that is used to run SOF processing modules on developers PC. This allows for module development using regular host based tooling.
+
+Please run
+```bash
+./rebuild-testbench.sh --help
+```
+for full options.
+
+Testbench can be also be built for Cadence simulator targets.
+
+### Tools and Topologies
+
+Tooling and topology can be built together using one script. To build all topologies please run:
+
+```bash
+./scripts/build-tools.sh
+```
+
+This script can build:
+1) sof-ctl
+2) sof-logger
+3) probes
+4) all topology 1 & 2 and test topologies.
+5) Local ALSA git version for alsa-lib and alsa-utils that have features not yet in distro version of ALSA packages.
+
+## SDK Support
+
+There is some SDK support in this directory for speeding up or simplifying tasks with multiple steps.
+
+### New Modules
+
+A new module can be created by running the sdk-create-module script. This script will copy the template module and rename all strings, Cmakefiles, Kconfigs to match the new module. It will also create a UUID for the new module and a TOML manifest entry (for targets that need this).
+
+Please run
+```bash
+./sdk-create-module.py new_module_name
+```
+
+## Docker
+
+The docker container provided in docker_build sets up a build environment for
+building Sound Open Firmware. A working docker installation is needed to run
+the docker build container.
+
+Note: In order to run docker as non sudo/root user please run.
+```bash
+sudo usermod -aG docker your-user-name
+```
+Then logout and login again.
+
+Quick Start:
+
+First, build the docker container. This step needs to be done initially and
+when the toolchain or alsa dependencies are updated.
+```bash
+cd scripts/docker_build
+./docker-build.sh
+```
+After the container is built, it can be used to run the scripts.
+
+To build for tigerlake:
+```bash
+./scripts/docker-run.sh ./scripts/xtensa-build-all.sh -l tgl
+```
+or (may need password test0000 for rimage install)
+```bash
+./scripts/docker-run.sh ./scripts/xtensa-build-all.sh tgl
+```
+To rebuild the topology and logger:
+```bash
+./scripts/docker-run.sh ./scripts/build-tools.sh
+```
+An incremental sof.git build:
+```bash
+./scripts/docker-run.sh make
+```
+Or enter a shell:
+```bash
+./scripts/docker-run.sh bash
+```
