-Firmware-Action is a tool to simplify building firmware. Think of it as `Makefile` or `Taskfile` but specifically for firmware. The tool it-self is written entirely in [Golang](https://go.dev/).

-Motivation behind the creation is to unify building of firmware across development environments. The goal of firmware action is to run on your local machine but also in your CI/CD pipeline, with the same configuration producing the same output.

-There is also an independent python tool to prepare Docker containers to be used with Firmware-Action. These are hosted on GitHub and are freely available (no need to build any Docker containers yourself).

+At the moment firmware-action has modules to build:
 - [coreboot](https://coreboot.org/)
 - [linux](https://www.kernel.org/)
 - [tianocore / edk2](https://www.tianocore.org/)
 - firmware stitching (populating IFD regions with binaries)
 - [u-root](https://github.com/u-root/u-root)
+- universal module (run arbitrary commands in arbitrary Docker container)
 
 This list should expand in the future (see [issue 56](https://github.com/9elements/firmware-action/issues/56)).
 
-Firmware-Action is using [dagger](https://docs.dagger.io/) under the hood, which makes it a rather versatile tool. When Firmware-Action is used, it automatically downloads user-specified Docker containers in which it will attempt to build the firmware.

-If your firmware consists of multiple components, such as `coreboot` with `linux` as the payload, you can simply define each as a module and define dependency between them. Each module is built separately, but can use the output of another module as input. In the `coreboot` + `linux` example, you can call Firmware-Action to build `coreboot` recursively, which will also build `linux` due to the dependency definition. This way, you can build complex stacks of firmware in a single call.
