 The Open Component Model (OCM) is an open standard to describe software bills of delivery (SBOD). OCM is a technology-agnostic and machine-readable format focused on the software artifacts that must be delivered for software products.
 
-Check out the [the main OCM project web page](https://ocm.software) to find out what OCM offers you for implementing a secure software supply chain. It is your central entry point to all kind of OCM related [docs and guides](https://ocm.software/docs/overview/context), the [OCM specification](https://ocm.software/docs/overview/specification/) and all project [github repositories](https://github.com/open-component-model). It also offers a [Getting Started](https://ocm.software/docs/getting-started/) to quickly make your hands dirty with OCM, its toolset and concepts :smiley:

 ## OCM Specifications
 
-OCM describes delivery [artifacts](docs/ocm/model.md#artifacts) that can be accessed from many types of [component repositories](docs/ocm/model.md#repositories). It defines a set of semantic, formatting, and other types of specifications that can be found in the [`ocm-spec` repository](https://github.com/open-component-model/ocm-spec). Start learning about the core concepts of OCM elements [here](https://github.com/open-component-model/ocm-spec/tree/main/doc/specification/elements).

 ## OCM Library
 
 This project provides a Go library containing an API for interacting with the
 [Open Component Model (OCM)](https://github.com/open-component-model/ocm-spec) elements and mechanisms.
 
-The library currently supports the following [repository mappings](docs/ocm/interoperability.md):

   repository.

 ## Examples
+
 An example of how to use the `ocm` CLI in a Makefile can be found in [`examples/make`](https://github.com/open-component-model/ocm/blob/main/examples/make/Makefile).
 
 More comprehensive examples can be taken from the [`components`](https://github.com/open-component-model/ocm/tree/main/components) contained in this repository. [Here](components/helmdemo/README.md) a complete component build including a multi-arch image is done and finally packaged into a CTF archive which can be tranported into an OCI repository. See the readme files for details.
