-**EthereumJS Ecosystem**
-
-This project will be embedded in the EthereumJS ecosystem and many submodules already exist and
-can be used within the project, have a look e.g. at [ethereumjs-block](https://github.com/ethereumjs/ethereumjs-block), [ethereumjs-vm](https://github.com/ethereumjs/ethereumjs-vm), the
-[merkle-patricia-tree](https://github.com/ethereumjs/merkle-patricia-tree) or the
-[ethereumjs-devp2p](https://github.com/ethereumjs/ethereumjs-devp2p) implementation.
-
-To play well together within a client context, many sub module libraries need enhancements,
-e.g. to create a common logging context. There are also larger building blocks still
-missing, e.g. the [Node Discovery V5](https://github.com/ethereumjs/ethereumjs-devp2p/issues/19)
-p2p implementation being necessary for a proper working light client sync. Due to the distributed
-nature of EthereumJS there will be internal (to be done in this repo) and external issues
-(to be done in other EthereumJS repos) to be worked on.
-
-All (hopefully :-)) issues referring to the client implementation will be provided with a
-``ethereumjs-client`` label which should be discoverable with a label search on GitHub:

-
-**Basic Environment**
-
-For library development the following basic environment is targeted. Some base requirements
-like the testing tool arise from the need of maintaining a somewhat unified EthereumJS environment
-where developers can switch between with some ease without the need to learn (too much) new
-tooling.

-## Contribution Guidelines
-**Communication** This is distributed team effort. If you plan to take on larger issues
-always pre-announce your work intention on the issue page and drop a short note on what
-you are planning to do. If there is no issue for the stuff you want to work on create one
-and describe the problem and outline the intended implementation before start working.

-**Branch Structure**
+## Environment / Ecosystem
 
-Development will take place via feature branches being merged against a protected ``master``
-branch. Always develop on branch also when being on your own fork, use meaningful branch
-names like ``new-debug-cl-option`` or ``fixed-this-really-annoying-bug``.

-No meaningful new PR will be accepted without associated tests (exceptions might be done on
-a case-by-case basis). Test coverage should not increase (significantly) by a new PR.
-You might also want to consider writing your tests first and then directly push them,
-since this would be a good starting point for discussing the scope/implementation of a feature.
