+
+## Working with locally deployed contracts
+
+The smart contracts and their JavaScript wrapper library are developed in the
+[truffle-kredits](https://github.com/67P/truffle-kredits) repo/package.
+
+You can run `kredits-web` on your machine, against a local, simulated Ethereum
+network, provided e.g. by [ganache](http://truffleframework.com/ganache/) or
+[ganache-cli](https://github.com/trufflesuite/ganache-cli).
+
+[truffle-kredits](https://github.com/67P/truffle-kredits) holds all the tools
+to start and set up such a simulated network, as well as to deploy smart
+contracts to it.
+
+These are the basic steps to get up and running:
+
+#### 1. IPFS
+
+Run a local IPFS deamon in offline mode.
+
+  * Make sure CORS headers are configured. See [IPFS](#ipfs) for more info.
+  * `ipfs daemon --offline`
+
+#### 2. truffle-kredits
+
+Get your local Ethereum development node running.
+
+  * Clone [truffle-kredits](https://github.com/67P/truffle-kredits)
+  * `npm install`
+  * `npm run ganache` - which is basically: `ganache-cli -p 7545 -i 100` (we use the non-default port for local networks and a fixed network id)
+  * `npm run bootstrap` - bootstrap runs fresh migrations, adds some seed data and writes the address/abi information to JSON that will be used by kredits-web
+  * `npm link` - make the `truffle-kredits` module linkable as `kredits-contracts` on your machine
+
+#### 3. kredits-web
+
+With IPFS and Ethereum/ganache running, you can now start this Ember app.
+
+  * `npm link kredits-contracts` - link the local `truffle-kredits` package (it will become `kredits-contracts` soon)
+  * `npm start`
+
+#### IPFS
+
+Install IPFS with your favorite package manager and run
+
+    ipfs init (on initial installation)
+    ipfs config --json API.HTTPHeaders.Access-Control-Allow-Origin '["localhost:4200"]'
+    ipfs config --json API.HTTPHeaders.Access-Control-Allow-Methods '["PUT", "GET", "POST"]'
+    ipfs config --json API.HTTPHeaders.Access-Control-Allow-Credentials '["true"]'
