+
+trestle-bot assists users in leveraging [Compliance-Trestle](https://github.com/oscal-compass/compliance-trestle) in CI/CD workflows for [OSCAL](https://github.com/usnistgov/OSCAL) formatted compliance content management.
+
+> WARNING: This project is currently under initial development. APIs may be changed incompatibly from one commit to another.
+
+## Getting Started
+
+### Available Commands
+
+The `autosync` command will sync trestle-generated Markdown files to OSCAL JSON files in a trestle workspace. All content under the provided markdown directory when the action is run will be transformed. This action supports all top-level models [supported by compliance-trestle for authoring](https://oscal-compass.github.io/compliance-trestle/tutorials/ssp_profile_catalog_authoring/ssp_profile_catalog_authoring/).
+
+The `rules-transform` command can be used when managing [OSCAL Component Definitions](https://pages.nist.gov/OSCAL-Reference/models/v1.1.1/component-definition/json-outline/) in a trestle workspace. The action will transform rules defined in the rules YAML view to an OSCAL Component Definition JSON file.
+
+The `create-cd` command can be used to create a new [OSCAL Component Definition](https://pages.nist.gov/OSCAL-Reference/models/v1.1.1/component-definition/json-outline/) in a trestle workspace. The action will create a new Component Definition JSON file and corresponding directories that contain rules YAML files and trestle-generated Markdown files. This action prepares the workspace for use with the `rules-transform` and `autosync` actions.
+
+The `sync-upstreams` command can be used to sync and validate upstream OSCAL content stored in a git repository to a local trestle workspace. Which content is synced is determined by the `include_model_names` and `exclude_model_names` inputs.
+
+The `create-ssp` command can be used to create a new [OSCAL System Security Plans](https://pages.nist.gov/OSCAL-Reference/models/v1.1.1/system-security-plan/json-outline/) (SSP) in a trestle workspace. The action will create a new SSP JSON file and corresponding directories that contain trestle-generated Markdown files. This action prepares the workspace for use with the `autosync` action by creating or updating the `ssp-index.json` file. The `ssp-index.json` file is used to track the relationships between the SSP and the other OSCAL content in the workspace for the `autosync` action.
+
+Below is a table of the available commands and their current availability as a GitHub Action:
+
+| Command            | Available as a GitHub Action |
+|--------------------|------------------------------|
+| `autosync`         | ✓                     |
+| `rules-transform`  | ✓                     |                   
+| `create-cd`        | ✓                     |
+| `sync-upstreams`   | ✓                     |
+| `create-ssp`       |                              |
+
+For detailed documentation on how to use each action, see the README.md in each folder under [actions](./actions/).

+
+### Run as a Container
+
+> Note: When running the commands in a container, all are prefixed with `trestlebot` (e.g. `trestlebot-autosync`). The default entrypoint for the container is the autosync command.
+
+Build and run the container locally:
+
+```bash
+podman build -f Dockerfile -t trestle-bot .
+podman run -v $(pwd):/data -w /data trestle-bot
+```
+
+Container images are available in `quay.io`:
+
+```bash
+podman run -v $(pwd):/data -w /data quay.io/continuouscompliance/trestle-bot:<tag>
+```
