+# System Requirement Specification OpenFastTrace GitHub Action
+
+## Introduction
+
+[OpenFastTrace](https://github.com/itsallcode/openfasttrace) (OFT) is a requirement tracing suite written in Java.
+The OpenFastTrace Action wraps the execution of the OpenFastTrace `trace` command in a [GitHub Action](https://docs.github.com/en/actions).
+
+### Goals
+
+The main goal of the OFT Action is to provide an easy way to execute OpenFastTrace as part of [CI/CD pipelines implemented by means of GitHub Actions workflows](https://docs.github.com/en/actions/about-github-actions/about-continuous-integration-with-github-actions).
+
+## Features
+
+### Standard GitHub Action
+`feat~standard-github-action~1`
+
+The OFT Action is a standard GitHub Action which allows running the OpenFastTrace `trace` command on files in the local workspace.
+
+Rationale:
+
+Verifying that all requirements are covered by the code base is an important aspect of a CI build. Projects hosted on GitHub often use GitHub Actions based CI workflows. It has always been possible to run OFT from within a shell script executed as part of a workflow job. However, the script code tends to be rather boilerplate so it seems reasonable to provide a standard GitHub Action that can be used as easily as other already existing Actions.
+
+Needs: req
+
+## Functional Requirements
+
+### Run OFT trace command
+`req~run-oft-trace-command~1`
+
+The OFT Action runs the OpenFastTrace `trace` command.
