message: Added references to all repos, projects boards to orient a dev looking at the repo
diff: This repo provides a useful functionality to build smart contracts that
  are compatible with Cosmos SDK runtime, [currently being developed](https://github.com/cosmwasm/cosmos-sdk/issues).
  +## Overview
  +
  +This crate provides the bindings and all imports needed to build a smart contract.
  +However, to get that contract to interact with a system needs many moving parts.
  +To get oriented, here is a list of the various components of the CosmWasm ecosystem:
  +
  +* [cosmwasm](https://github.com/confio/cosmwasm) - This crate. All needed functionality and no more - to build a small, efficient wasm smart contract.
  +
  +**Building contracts:**
  +
  +* [cosmwasm-template](https://github.com/confio/cosmwasm-template) - A starter-pack to get you quickly building your custom contract compatible with the cosmwasm system.
  +* [cosmwasm-opt](https://github.com/confio/cosmwasm-opt) - A docker image and scripts to take your rust code and produce the smallest possible wasm output. *Deterministically*
  +This is designed both for preparing contracts for deployment as well as validating that a given deployed contract is based on some given rust code.,
  +allow a [similar contract verification algorithm](https://medium.com/coinmonks/how-to-verify-and-publish-on-etherscan-52cf25312945) as etherscan.
  +* [serde-json-wasm](https://github.com/confio/serde-json-wasm) - A custom json library, forked from `serde-json-core`. This provides an interface similar to
  +`serde-json`, but without ay floating-point instructions (non-deterministic) and producing builds
  +around 40% of the code size.
  +
  +**Executing contracts:**
  +
  +* [cosmwasm-vm](https://github.com/confio/cosmwasm/tree/master/lib/vm) - A sub-crate. Uses the [wasmer](https://github.com/wasmerio/wasmer) engine
  +to execute a given smart contract. Also contains code for gas metering, storing, and caching wasm artifacts. Read more [here](https://github.com/confio/cosmwasm/blob/master/lib/vm/README.md).
  +* [go-cosmwasm](https://github.com/confio/go-cosmwasm) - High-level go bindings to all the power inside `cosmwasm-vm`. Easily allows you to upload, instantiate and execute contracts,
  +making use of all the optimizations and caching available inside `cosmwasm-vm`.
  +* [Cosmos SDK](https://github.com/cosmwasm/modules/tree/master/incubator/contract) - Currently an WIP fork targeting `cosmos/modules`
  +to provide an wasm module you can easily plug into any Cosmos-SDK based application.
  +
  +Ongoing work is currently tracked [on this project board](https://github.com/orgs/confio/projects/1)
  +for all of the internals, and [on this project board](https://github.com/cosmwasm/modules/projects/3)
  +for the Cosmos-SDK integration work.

  ## Creating a Smart Contract
  You can see some examples of contracts under the `contracts` directory,
