+# Kredits Web
 
-This README outlines the details of collaborating on this Ember application.
-A short introduction of this app could easily go here.
+This is the main Web UI for Kosmos [Kredits](https://wiki.kosmos.org/Kredits).
+It provides an overview of contributors and contributions, as well as the
+community's budget, expenses, and reimbursements.
 
-## Prerequisites
+It is an unhosted Web app, fetching all data from
+[Rootstock](https://rootstock.io/) and [IPFS](https://ipfs.tech/), and caching
+it in the browser's local database. As such, you can run the app directly from
+the `/release` directory on any Web server that can serve static assets.
+
+## Development
+
+### Prerequisites
 
 You will need the following things properly installed on your computer.
 
 * [Git](https://git-scm.com/)
 * [Node.js](https://nodejs.org/) (with npm)
 * [Ember CLI](https://ember-cli.com/)
-* [Google Chrome](https://google.com/chrome/)

 * `git clone git@github.com:67P/kredits-web.git` this repository
 * `cd kredits-web`
 * `npm install`
 
-## Running / Development

-* Visit your app at [http://localhost:4200](http://localhost:4200).
-* Visit your tests at [http://localhost:4200/tests](http://localhost:4200/tests).
+* `npm start` - by default Kredits Web connects to the Rootstock testnet network
+* Visit the app at [http://localhost:4200](http://localhost:4200).
+* Visit the tests at [http://localhost:4200/tests](http://localhost:4200/tests).

-[ganache-cli](https://github.com/trufflesuite/ganache-cli).

+You can run `kredits-web` on your machine, against a local, simulated
+blockchain. [kredits-contracts](https://github.com/67P/kredits-contracts)
+contains all the tools to start and set up such a simulated network, as well as
+to deploy the Kredits smart contracts to it.
 
 These are the basic steps to get up and running:
 
 #### 1. IPFS
 
-Run a local IPFS deamon in offline mode.
+Run a local IPFS deamon.
 
   * Make sure CORS headers are configured. See [IPFS](#ipfs) for more info.
-  * `ipfs daemon --offline`
+  * `ipfs daemon`
 
-#### 2. truffle-kredits
+#### 2. kredits-contracts
 
-Get your local Ethereum development node running.
+Run a local devchain with test data. (See [kredits-contracts
+README](https://github.com/67P/kredits-contracts) for details.
 
-  * Clone [truffle-kredits](https://github.com/67P/truffle-kredits)
+  * 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 `truffle-kredits` module linkable as `kredits-contracts` on your machine
+  * `npm run devchain` - runs a local development chain
+  * `npm run bootstrap` - deploys all contracts and seeds test data
+  * `npm link` - makes 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.
+With IPFS and the local devchain running, you can now link the contracts and
+start the Ember app:
 
-  * `npm link kredits-contracts` - link the local `truffle-kredits` package (it will become `kredits-contracts` soon)
-  * `npm start`
+  * `npm link kredits-contracts` - links the local `kredits-contracts` package (has to be done again after every `npm install`)
+  * `npm run start:local` - runs the Ember app with WEB3_PROVIDER_URL=http://localhost:8545 set
+
+#### 4. Metamask network
+
+If you want to interact with the local contracts via a Web3 wallet, switch the
+network to a "Custom RPC" one, with the RPC URL `http://localhost:8545`.
 
 #### IPFS
 
-Install IPFS with your favorite package manager and run
+If you haven't configured your IPFS node for CORS yet, you can do so by running
+the following commands:
 
-    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"]'
