-# Kredits Contracts
-
-This repository contains the Solidity smart contracts organized as
-[Aragon](https://hack.aragon.org/) apps and JavaScript API wrapper for [Kosmos
-Kredits](https://wiki.kosmos.org/Kredits).
-
-It is based on [aragonOS](https://hack.aragon.org/docs/aragonos-intro.html) and
-follows the aragonOS conventions.  Aragon itself uses the [Truffle
-framework](http://truffleframework.com/) for some things.
-
-## Development
-
-### Installation
-
-#### App dependencies
-
-All requirements are defined in `package.json`.
-
-    $ npm install
-
-Each of the aragon apps are separate packages:
-
-    $ cd apps/[app]
-    $ npm install
-
-You can use `npm run install-all` to install all app dependencies at once.
-
-#### Sytem dependencies
-
-Aragon CLI and Truffle need to be installed on your sytem as well:
-
-    npm install -g @aragon/cli
-    npm install -g truffle
-
-### Local development chain
-
-For local development it is recommended to use
-[ganache](http://truffleframework.com/ganache/) to run a local development
-chain. When using the ganache simulator, no full Ethereum node is required.
-
-We use the default aragon-cli devchain command to configure and run a local
-development ganache.
-
-    $ npm run devchain (or aragon devchain --port 7545)
-
-To clear/reset the chain use (e.g. if you run out of funds on your devchain)
-
-    $ npm run devchain -- --reset (or aragon devchain --port 7545 --reset)
-
-We default to port 7545 for development to not get in conflict with the default
-Ethereum RPC port.
-
-You can also set certain ganache options to configure the devchain, for example
-if you want to increase the block time to 10 seconds you can add
-`--block-time=10`.
-
-### Bootstrap
-
-1. Run an Ethereum node and ipfs
-
-        $ npm run devchain
-        $ ipfs daemon
-
-2. Deploy each app to the devchain
-
-        (make sure you've run `npm install` for every app - see installation)
-        $ npm run deploy:apps
-
-3. Deploy a new KreditsKit and create a new DAO with the latest app versions
-
-        $ npm run deploy:kit
-        $ npm run deploy:dao
-
-4. Execute seeds to create demo contributors, contributions, etc. (optional)
-
-        $ npm run seeds
-
-**Step 2-4 is also summarized in `npm run bootstrap`**
-
-If you want to reset your local setup:
-
-        $ npm run reset // deploys a new kit and a new DAO
-        $ npm run reset:hard // deploys all apps and does reset
-
-## Contract architecture
-
-Contracts are organized in independent apps (see `/apps`) and are developed and
-deployed independently. Each app has a version and can be "installed" on the
-Kredits DAO independently.
-
-![](docs/kredits-diagram.png)
-
-A DAO can be deployed using the `scripts/deploy-kit.js` script or with the
-`npm run deploy:dao` command. This deploys a new Kredits DAO, installs the
-latest app versions and sets the required permissions.
-
-See each app in `/apps/*` for details.
-
-
-## Helper scripts
-
-`scripts/` contains some helper scripts to interact with the contracts from the
-CLI. _At some point these should be moved into a real nice CLI._
-
-To run these scripts use `truffle exec`. For example: `truffle exec
-scripts/add-proposal.js`.
-
-Some scripts are also defined as npm script, see package.json.
-
-### cli.js
-
-Call any function on any contract:
-
-    $ truffle exec scripts/cli.js
-
-### repl.js
-
-Similar to cli.js but only provides a REPL with an initialized `kredits`
-instance.
-
-    $ truffle exec scripts/repl.js
-
-### add-{contributor, contribution, proposal}.js
-
-Script to add a new entries to the contracts using the JS wrapper
-
-    $ truffle exec scripts/add-{contributor, contribution, proposal}.js
-
-### list-{contributors, contributions, proposals}.js
-
-List contract entries
-
-    $ truffle exec scripts/list-{contributors, contributions, proposals}.js
-
-### send-funds.js
-
-Sends funds to an address. Helpful in development mode to for example fund a
-metamask account.
-
-    $ truffle exec scripts/send-funds.js
-
-### seeds.js
-
-Run seeds defined in `config/seeds.js`.
-
-    $ truffle exec scripts/seeds.js
-    or
-    $ npm run seeds
-
-### current-address.js
-
-Prints all known DAO addresses and the DAO address for the current network
-
-    $ truffle exec scripts/current-address.js
-    or
-    $ npm run dao:address
-
-### deploy-kit.js
-
-Deploys a new KreditsKit that allows to create a new DAO
-
-    $ truffle exec script/deploy-kit.js
-    or
-    $ npm run deploy:kit
-
-`ENS` address is required as environment variable.
-`DAO_FACTORY` can optionally be set as environment variable. (see aragon)
-
-### new-dao.js
-
-Creates and configures a new DAO instance.
-
-    $ truffle exec script/new-dao.js
-    or
-    $ npm run deploy:dao
-
-KreditsKit address is loaded from `lib/addresses/KreditsKit.json` or can be
-configured through the `KREDITS_KIT` environment variable.
-
-### deploy-apps.sh
-
-Runs `npm install` for each app and publishes a new version.
-
-    $ ./scripts/deploy-apps.sh
-    or
-    $ npm run deploy:apps
-
-## Deployment
-
-### Apps deployment
-
-To deploy a new app version run:
-
-    $ aragon apm publish major --environment=NETWORK_TO_DEPLOY
-
-### KreditsKit
-
-deploy the KreditsKit as Kit to create new DAOs
-
-    $ truffle exec scripts/deploy-kit.js --network=NETWORK_TO_DEPLOY
-
-### Creating a new DAO
-
-make sure all apps and the KreditsKit are deployed, then create a new DAO:
-
-    $ truffle exec scripts/new-dao.js --network=NETWORK_TO_DEPLOY
-
-## ACL / Permissions
-
-## Upgradeable contracts
-
-We use aragonOS for upgradeability of the different contracts.  Refer to the
-[aragonOS upgradeablity documentation](https://hack.aragon.org/docs/upgradeability-intro)
-for more details.
-
-### Example
-
-1. Setup (see #Bootstrap)
-    1. Deploy each contract/apps (see `/apps/*`)
-    2. Create a new DAO (see scripts/deploy-kit.js)
-2. Update
-    1. Deploy a new Version of the contract/app (see `/apps/*`)
-    2. Use the `aragon dao upgrade` command to "install" the new version for the DAO
-      (`aragon dao upgrade <DAO address> <app name>`)
-
-## Known Issues
-
-When resetting ganache Metamask might have an invalid transaction nonce and
-transactions get rejected. Nonces in Ethereum must be incrementing and have no
-gap.
-
-To solve this reset the metamask account (Account -> Settings -> Reset Account)

+# Kredits
+
+This repository contains all the contracts for Kredits as a [truffle framework](http://truffleframework.com/) project.
+
+## Development
+
+### Installation
+
+    $ npm install
+
+### Requirements
+
+All requirements are defined in `package.json`.
+
+Those can be installed globally for convenience: 
+  * [truffle framework](http://truffleframework.com): `npm install -g truffle`
+  * [ganache](http://truffleframework.com/ganache): `npm install -g ganache-cli`
+
+We use following solidity contract libraries:
+  * [Open Zeppelin](https://github.com/OpenZeppelin/zeppelin-solidity)
+
+For local development it is recommended to use [ganache-cli](https://github.com/trufflesuite/ganache-cli) (or the [ganache GUI](http://truffleframework.com/ganache/) to run a local development chain.  
+Using the ganache simulator no full Ethereum node is required.
+
+We default to: 
+
+* port 7545 for development to not get in conflict with the default Ethereum RPC port.
+* network ID 100 to stay on the same network id
+* store ganache data in .ganache-db to presist the chain data across restarts
+* use a fixed Mnemonic code to get the same accounts across restarts
+
+Have a look at `ganache-cli` for more configuration options.
+
+Run your ganache simulator before using Kredits locally:
+
+    $ npm run ganache (which is: ganache-cli -p 7545 -i 100 --db=./.ganache-db -m kredits)
+
+### Truffle console
+
+Truffle comes with a simple REPL to interact with the Smart Contracts. Have a look at the [documentation here](http://truffleframework.com/docs/getting_started/console)
+
+NOTE: There are promisses, have a look at the examples: 
+
+```javascript
+Token.deployed().then(function(token) { 
+  token.totalSupply.call().then(function(value) {
+    console.log(value.toString());
+  })
+});
+```
+
+Also please be aware of the differences between web3.js 0.2x.x and [1.x.x](https://web3js.readthedocs.io/en/1.0/) - [web3 repo](https://github.com/ethereum/web3.js/)
+
+
+## Contract Deployment
+
+Truffle uses migration scripts to deploy contract to various networks. Have a look at the `migrations` folder for those.  
+The Ethereum nodes for the different networks need to be configured in `truffle.js`.
+
+Run the truffle migration scripts: 
+
+    $ truffle deploy 
+    $ truffle deploy --network=<network config from truffle.js>
+
+Truffle keeps track of already executed migration scripts. To reset the migration use the `--reset` option
+
+    $ truffle migrate --reset
+
+Migration scripts can also be run from within `truffle console` or `truffle develop` 
+
+To initially bootstrap a local development chain in ganache you can use the bootstrap script:
+
+    $ npm run bootstrap (= `truffle migrate --reset && truffle exec scripts/seeds.js && npm run build-json`)
+
+
+## Helper scripts
+
+`scripts/` contains some helper scripts to interact with the contracts from the CLI. 
+At some point these should be moved into a real nice CLI. 
+
+To run these scripts use `truffle exec`. For example: `truffle exec scripts/add-proposal.js` 
+
+### cli.js
+
+Call any function on any contract:
+
+    $ truffle exec scripts/cli.js <Contract Name> <Function> [<optional> <arguments>]
+    
+    For example: 
+    $ truffle exec scripts/cli.js Operator proposalsCount
+
+Please note that the contract name and the function are case sensitive. 
+
+### add-contributor.js
+Adds a new core contributor, creates a proposal for the new contributor and votes for that one. 
+
+    $ truffle exec scripts/add-contributor.js <ethereum address> [<profile IPFS hash>]
+
+### add-proposal.js
+Adds a new proposal for an existing contributor
+
+    $ truffle exec scripts/add-proposal.js <ethereum address> [<proposal IPFS hash>]
+
+### send-funds.js
+Sends funds to an address. Helpful in development mode to for example fund a metamask account.
+
+    $ truffle exec scripts/send-funds.js <ethereum address>
+
+### seeds.js
+Run seeds defined in `config/seeds.js`.  
+
+    $ truffle exec scripts/seeds.js 
+    or 
+    $ npm run seeds
+
+
+## Upgradeable contracts
+
+Some of the contracts use upgradability ideas from [zeppelinos](https://github.com/zeppelinos/labs) (see `contracts/upgradable`).
+
+The basic idea is to have a Registry contract that knows about the current implementations and a Proxy contract that uses `delegatecall` to call the current implementation.  
+That means the Proxy contract holds the storage and the address of that one does not change but the actuall implemenation is managed through the Registry. 
+
+To deploy a new version a new contract is deployed then the version is registered (`addVersion()`) in the Registry and on the Proxy contract is "upgraded" (`upgrade()`) to the new version. 
+
+The Registry knows about all the different contracts and implementations. Versions are stored as uint and automatically incremented for every added implementation.
+
+
+### Example:
+
+Deployment is best done using the [truffle deployer]()
+
+1. Setup
+    1. deploy the Registry 
+    2. deploy the contract
+    3. register the contract at the Registry: 
+        `registry.addVersion('Token', Token.address)`
+    4. create the Proxy: 
+        `registry.createProxy('Token', 1)`
+2. Update
+    1. deploy a new Version of the contract
+    2. register the new version at the Registry: 
+        `registry.addVersion('Token', NewToken.address)`
+    3. set the new implementation address on the Proxy contract:
+        `registry.upgrade('Token', 2)`
+
+
+## Known Issues
+
+When resetting ganache Metamask might have an invalid transaction nonce and transactions get rejected. 
+Nonces in Ethereum must be incrementing and have no gap. 
+
+To solve this reset the metamask account (Account -> Settings -> Reset Account)
