-
-To ensure the authenticity and integrity of code contributions, **we require that all commits are signed**. Signing commits proves that your commits were truly created by you, as the holder of a private key.
-
-Configuring git to sign your commits is a straightforward process. To get set up, see [GitHub's documentation on signing commits](https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits).

+
+**Note**: Nix packaging of Syft is [community maintained](https://github.com/NixOS/nixpkgs/blob/master/pkgs/tools/admin/syft/default.nix). Syft is currently only in the [unstable channel](https://nixos.wiki/wiki/Nix_channels#The_official_channels) awaiting the `22.05` release

 ## Getting started

-To generate an SBOM for a Docker or OCI image:
+#### SBOM
+
+To generate an SBOM for a container image:
+
 ```
 syft <image>
 ```

-**Note**: This is equivalent to specifying the `packages` subcommand:
-```
-syft packages <image>
-```
-
-The above output includes only software that is visible in the container (i.e., the squashed representation of the image).
-To include software from all image layers in the SBOM, regardless of its presence in the final image, provide `--scope all-layers`:
+The above output includes only software that is visible in the container (i.e., the squashed representation of the image). To include software from all image layers in the SBOM, regardless of its presence in the final image, provide `--scope all-layers`:

 ```
-syft packages <image> --scope all-layers
+syft <image> --scope all-layers
 ```

+#### Format conversion (experimental)
+
+The ability to convert existing SBOMs means you can create SBOMs in different formats quickly, without the need to regenerate the SBOM from scratch, which may take significantly more time.
+
+```
+syft convert <ORIGINAL-SBOM-FILE> -o <NEW-SBOM-FORMAT>[=<NEW-SBOM-FILE>]
+```
+
+This feature is experimental and data might be lost when converting formats. Packages are the main SBOM component easily transferable across formats, whereas files and relationships, as well as other information Syft doesn't support, are more likely to be lost. 
+
+We support formats with wide community usage AND good encode/decode support by Syft. The supported formats are:
+- Syft JSON
+- SPDX 2.2 JSON
+- SPDX 2.2 tag-value
+- CycloneDX 1.4 JSON
+- CycloneDX 1.4 XML
+
+Conversion example:
+```sh
+syft alpine:latest -o syft-json=sbom.syft.json # generate a syft SBOM
+syft convert sbom.syft.json -o cyclonedx-json=sbom.cdx.json  # convert it to CycloneDX
+```
+
+#### SBOM attestation
+
+### Keyless support
+Syft supports generating attestations using cosign's [keyless](https://github.com/sigstore/cosign/blob/main/KEYLESS.md) signatures.
+
+To use this feature with a format like CycloneDX json simply run:
+```
+syft attest --output cyclonedx-json <IMAGE WITH OCI WRITE ACCESS>
+```
+This command will open a web browser and allow the user to authenticate their OIDC identity as the root of trust for the attestation (Github, Google, Microsoft).
+
+After authenticating, Syft will upload the attestation to the OCI registry specified by the image that the user has write access to.
+
+You will need to make sure your credentials are configured for the OCI registry you are uploading to so that the attestation can write successfully.
+
+Users can then verify the attestation(or any image with attestations) by running:
+```
+COSIGN_EXPERIMENTAL=1 cosign verify-attestation <IMAGE_WITH_ATTESTATIONS>
+```
+
+Users should see that the uploaded attestation claims are validated, the claims exist within the transparency log, and certificates on the attestations were verified against [fulcio](https://github.com/SigStore/fulcio).
+There will also be a printout of the certificates subject `<user identity>` and the certificate issuer URL: `<provider of user identity (Github, Google, Microsoft)>`:
+```
+Certificate subject:  test.email@testdomain.com 
+Certificate issuer URL:  https://accounts.google.com
+```
+
+### Local private key support
+
+To generate an SBOM attestation for a container image using a local private key:
+```
+syft attest --output [FORMAT] --key [KEY] [SOURCE] [flags]
+```
+
+The above output is in the form of the [DSSE envelope](https://github.com/secure-systems-lab/dsse/blob/master/envelope.md#dsse-envelope).
+The payload is a base64 encoded `in-toto` statement with the generated SBOM as the predicate. For details on workflows using this command see [here](#adding-an-sbom-to-an-image-as-an-attestation-using-syft).
+
 ### Supported sources

 Syft can generate a SBOM from a variety of sources:

 ```
 # catalog a container image archive (from the result of `docker image save ...`, `podman save ...`, or `skopeo copy` commands)
-syft packages path/to/image.tar
+syft path/to/image.tar

 # catalog a directory
-syft packages path/to/dir
+syft path/to/dir
 ```

 Sources can be explicitly provided with a scheme:

 ```
 docker:yourrepo/yourimage:tag          use images from the Docker daemon
+podman:yourrepo/yourimage:tag          use images from the Podman daemon
 docker-archive:path/to/yourimage.tar   use a tarball from disk for archives created from "docker save"

-### Adding an SBOM to an image as an attestation
-SBOMs themselves can serve as input to different analysis tools. The Anchore organization offers the vulnerability scanner
-[grype](https://github.com/anchore/grype) as one such tool.
-One of the foundational approaches to "trust" between tools is for producers to use the artifacts generated by syft as attestations to their images.
-The SBOM output of syft can be used with the [cosign](https://github.com/sigstore/cosign) tool to generate an attestation that is attached to a signed image.
+### Adding an SBOM to an image as an attestation using Syft

-#### Example attest
-Note for the following example replace `test/image:latest` with an image you own. You should also have push access to 
-its remote reference. Replace $MY_PRIVATE_KEY with a private key you own or have generated with cosign.

+SBOMs themselves can serve as input to different analysis tools. [Grype](https://github.com/anchore/grype), a vulnerability scanner CLI tool from Anchore, is one such tool. Publishers of container images can use attestations to enable their consumers to trust Syft-generated SBOM descriptions of those container images. To create and provide these attestations, image publishers can run `syft attest` in conjunction with the [cosign](https://github.com/sigstore/cosign) tool to attach SBOM attestations to their images.
