Remove aragon-cli as direct development dependency

aragon-cli now is a global pre-requirement and not direct dependency
anymore.
The uncountable npm dependencies and npm package.json hacks in the
aragon-cli package made it too hard to maintain.

 # Kredits Contracts
 
-This repository contains the Solidity smart contracts and the JavaScript API
-wrapper for [Kosmos Kredits](https://wiki.kosmos.org/Kredits).
+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.
+
 ### Local development chain
 
-We use [hardhat](https://hardhat.org/) as development environment for the
-smart contracts.
+For local development it is recommended to use
+[ganache](http://truffleframework.com/ganache/) to run a local development
+chain. Using the ganache simulator no full Ethereum node is required.
 
-To run a local development chain run:
+We use the default aragon-cli devchain command to confgure and run a local
+development ganache.
 
-    $ npm run devchain # or: hardhat node --network hardhat
+    $ 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.
 
 ### Bootstrap
 
-1.  Run an Ethereum node and ipfs
+1. Run an Ethereum node and ipfs
 
         $ npm run devchain
         $ ipfs daemon
 
-2.  Compile contracts and build ABIs
+2. Deploy each app to the devchain
 
-        (compiled artifacts will be in `/artifacts`)
-        $ npm run build
+        (make sure you've run `npm install` for every app - see installation)
+        $ npm run deploy:apps
 
-3.  Deploy new upgradable contract proxies
+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)
+4. Execute seeds to create demo contributors, contributons, etc. (optional)
 
         $ npm run seeds
 
 **Step 2-4 is also summarized in `npm run bootstrap`**
 
-5.  Show contract addresses
+If you want to reset your local setup:
 
-        $ cat lib/addresses.json
-
-## Fund a local development account
-
-If you need to fund development accounts with devchain coins:
-
-    $ npm run fund # or hardhat fund --network localhost
+        $ npm run reset // deploys a new kit and a new DAO
+        $ npm run reset:hard // deploys all apps and does reset
 
 ## Contract architecture
 
-We use the [OpenZeppelin hardhat
-proxy](https://www.npmjs.com/package/@openzeppelin/hardhat-upgrades) for
-deploying and managing upgradeable contracts. (see `scripts/create-proxy.js`)
+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.
 
-Each contract is independent and is connected to its dependencies by storing
-the addresses of the other contracts.
 
 ## 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 `hardhat run`. For example: `hardhat run
-scripts/list-contributors.js --network localhost`. (NOTE: add `--network
-localhost` or the network you want to use)
+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`.
+Some scripts are also defined as npm script, see package.json.
 
-### repl/console
+### 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.
 
-    $ hardhat console --network localhost
+    $ truffle exec scripts/repl.js
 
 ### add-{contributor, contribution, proposal}.js
 
 Script to add a new entries to the contracts using the JS wrapper
 
-    $ hardhat run scripts/add-{contributor, contribution, proposal}.js --network localhost
+    $ truffle exec scripts/add-{contributor, contribution, proposal}.js
 
 ### list-{contributors, contributions, proposals}.js
 
 List contract entries
 
-    $ hardhat run scripts/list-{contributors, contributions, proposals}.js --network localhost
+    $ 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
 
-### Get the contract addresses
+### current-address.js
 
-All contract addresses are stored in `lib/addresses.json`
+Prints all known DAO addresses and the DAO address for the current network
 
-    $ cat lib/addresses.json
+    $ 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 load 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 OpenZeppelin for an upgradeable contracts:
-[https://www.npmjs.com/package/@openzeppelin/hardhat-upgrades](https://www.npmjs.com/package/@openzeppelin/hardhat-upgrades)
+We use aragonOS for upgradeablity of the different contracts.  Refer to the
+[aragonOS upgradeablity documentation](https://hack.aragon.org/docs/upgradeability-intro)
+for more details.
 
-Refer to the OpenZeppelin README and `scripts/create-proxy.js`
-
-[OpenZeppelin Step by Step guide](https://forum.openzeppelin.com/t/openzeppelin-upgrades-step-by-step-tutorial-for-hardhat/3580)
-
-For an upgrade example checkout `scripts/upgrade-example.js`
-
-
-## Deployment to other networks
-
-Deployable networks are configured in the `hardhat.config.js`.
-
-To deploy to those networks provide the `--network` argument to the hardhat
-commands, e.g. `--network rsk`.
-
-Please note that some npm scripts combine multiple hardhat commands. In those
-cases the hardhat commands needs to be run manually with the `--network`
-argument. (=> don't use `npm run bootstrap`)
-
-Set a `DEPLOY_KEY` environment variable with the private key (HEX) which will
-be used as a root/deploy account
-
-Typical deployment flow:
-
-    $ npm run build
-    $ hardhat run scripts/create-proxy.js --network rsk
-    # OR with deploy key:
-    $ DEPLOY_KEY=0xsomething hardhat run scripts/create-proxy.js --network rsk
-    $ # commit the new addresses in the addresses.json file if needed
-
-To run the console on one of the non localhost networks you can also just pass
-on the --network argument.
-
-    $ hardhat console --network rsk
+### 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>`)
