- > Both the ghc-mod and ide-backend maintainers have agreed to contribute code to this new repository and then rebase the old repos on this. The reason we're using a new repo instead of modifying one of the existing ones is so that the existing projects experience no disruption during this migration process. If this was a new set of people starting a new project without support from existing projects, I'd agree with you. But Alan's reached out to existing players already, which is an important distinction.

-## Architecture
-
-Below you find a short overview of the main architectural layers of `haskell-ide-engine`.
-For more info have a look in [the docs folder](/docs) at the root of this project, especially:
-
- - The [Architecture discussion](docs/Architecture.md)
- - The [Protocol discussion](docs/Protocol.md)
- - The [Design discussion](docs/Design.md)

-### 1. BIOS layer
-
-[`ghc-mod`](https://github.com/kazu-yamamoto/ghc-mod) stays an AGPL project,
-and is used for its "awesome sauce" in terms of
-the BIOS functions that it does so well. This interface is
-[straightforward to use](http://alanz.github.io/haskell%20refactorer/2015/10/02/ghc-mod-for-tooling),
-and if a license-constrained user wants to do something else it is also easy to
-replace, if there is strong control of the operating environment.
-
-### 2. Plugin layer
-
-A layer providing a point to integrate tools and existing functions, probably
-including ghci.
-
-### 3. IDE interfacing layer
+## Documentation
 
-The focus is currently on [LSP](https://github.com/Microsoft/language-server-protocol/blob/master/protocol.md) as the protocol we use to interface with IDEs.
+All the documentation is in [the docs folder](/docs) at the root of this project.
 
-Existing transports are still functional for the time being.
