-## Getting started
-
-Welcome to the Cloud Native AI Model Format Specification project! We are excited to have you contribute. Here are some steps to help you get started.
-
-## Setting up your local environment
-
-* **Clone the repository**:
-
-```sh
-git clone https://github.com/modelpack/model-spec.git
-cd model-spec
-```
-
-* **Install dependencies**: Ensure you have [Go](https://go.dev/) installed, as the current spec implementation is written in Go. Follow the [official instructions to install Go](https://go.dev/doc/install).
-
-## Where to put changes
-
-Right now, we have a simple directory structure:
-
-* `docs`: All detailed documents about the model spec.
-* `docs/img`: Any referenced images in the documents should be put here.
-* `specs-go`: A Go implementation of the model specification.
-
-## Raise a pull request

-
-* **Open a pull request**: Go to the GitHub repository, compare your branch, and submit a pull request with a detailed description of your changes.
-
-## Make sure pull request CI passes
-
-Please check the CI status in your pull request and fix anything that fails. Here are some simple instructions to validate CI locally.
