 # Internet Computer Reference
 
-**A preview of the latest `master` branch can be found [here](https://khsfq-wqaaa-aaaak-qckvq-cai.icp0.io/docs).**
-
-**The latest *released* version can be found [here](https://internetcomputer.org/docs/current/references/ic-interface-spec).**
-
-This repository contains the source files of the Interface Spec, which describes the externally visible behaviour of the Internet Computer.
-The language-independent description of this IC interface is available in [ic.did](./spec/_attachments/ic.did).
-
-It used to contain a reference implementation and acceptance test suite; these can now be found at [https://github.com/dfinity/ic-hs](https://github.com/dfinity/ic-hs).
-
-## About the Interface Spec
-
-This document describes the external interface of the Internet Computer. It is the authoritative source for interface details (request and function names, parameters, encodings). The goal is to have a document that is authoritative, and provides a place and a language to discuss external features of the Internet Computer in a hopefully concrete way. However, this document intentionally does not address _how_ to implement this behavior, and cannot be used as an implementation spec.
-
-## Versioning
-
-The Interface Spec is versioned, using a three-component version like
-
-    0.2.1
-
-Releases from this repository are tagged using a three-component _code
-version_ number:
-
-    0.8.1
-    ┬ ┬ ┬
-    │ │ └ The third component is bumped upon non-breaking changes to the spec.
-    │ └ The second component is bumped with a breaking change to the spec
-    └ Always zero for now.
-
-Each major spec version has a release branch (e.g. `release-0.8`) that only sees
-non-breaking changes and bugfixes. A release branch should typically be “ahead” of all previous release branches.
-
-The `master` branch contains finished designs, but is not directly scheduled
-for implementation. It lists version version number `∞`. The reference
-implementation on this branch typically does _not_ fully implement the spec. This branch should always be “ahead” of all the release branches.
