 ### Deploying
 
-Specify what it takes to deploy your app.
+_(You need collaborator permissions on the 5apps Deploy project.)_
 
+`npm run deploy`
 
 ## Working with locally deployed contracts
 
-For development you might want to run your own development chain with your own development contracts.
+The smart contracts and their JavaScript wrapper library are developed in the
-The kredits-contracts helper scripts are available in kredits-web. See [kredits-contracts](https://github.com/67P/kredits-contracts) for more information.
+[kredits-contracts](https://github.com/67P/kredits-contracts) repo/package.
 
-Start your parity node with a KreditsChain: 
+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).
 
-    npm run kredits-parity
+[kredits-contracts](https://github.com/67P/kredits-contracts) holds all the tools
+to start and set up such a simulated network, as well as to deploy smart
+contracts to it.
 
-Deploy the contracts to your local chain: 
+These are the basic steps to get up and running:
 
-    npm run kredits-deploy
+#### 1. IPFS
 
-Run kredits-web with your localy deployed contracts: 
+Run a local IPFS deamon in offline mode.
 
-    KREDITS_CONTRACT_ADDR=`kredits-inspect -c Kredits -r -w address` \
+  * Make sure CORS headers are configured. See [IPFS](#ipfs) for more info.
-    TOKEN_CONTRACT_ADDR=`kredits-inspect -c Token -r -w address` \
+  * `ipfs daemon --offline`
-    npm start
 
-    You need to have `./node_modules/.bin` in your path for this to work. Otherwise simply copy the contract addresses and set the environment variables manually.
+#### 2. kredits-contracts
 
+Get your local Ethereum development node running.
 
+  * Clone [kredits-contracts](https://github.com/67P/kredits-contracts)
+  * `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 `kredits-contracts` 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 `kredits-contracts` package
+  * `npm run start:local` - NETWORK_ID=100 and WEB3_PROVIDER_URL=http://localhost:7545 must be set for local settings
+
+#### 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"]'
