**Parity requires Rust version 1.12.0 to build**
----
## About Parity
Parity's goal is to be the fastest, lightest, and most secure Ethereum client. We are developing Parity using the sophisticated and
cutting-edge Rust programming language. Parity is licensed under the GPLv3, and can be used for all your Ethereum needs.
By default, Parity will run a JSONRPC server on `127.0.0.1:8545`. This is fully configurable and supports a number
of RPC APIs.
Parity comes with a built-in wallet. To access [Parity Wallet](http://127.0.0.1:8080/) this simply go to http://127.0.0.1:8080/. It
includes various functionality allowing you to:
- create and manage your Ethereum accounts;
- manage your Ether and any Ethereum tokens;
- create and register your own tokens;
- and much more.
Parity also runs a server for running decentralized apps, or "Dapps", on `http://127.0.0.1:8080`.
This includes a few useful Dapps, including Ethereum Wallet, Maker OTC, and a node status page.
In a near-future release, it will be easy to install Dapps and use them through this web interface.
By default, Parity will also run a JSONRPC server on `127.0.0.1:8545`. This is fully configurable and supports a number
of RPC APIs.
If you run into an issue while using parity, feel free to file one in this repository
or hop on our [gitter chat room][gitter-url] to ask a question. We are glad to help!

Parity also requires `gcc`, `g++` and `make` packages to be installed.

### Using systemd service file
To start Parity as a regular user using systemd init:
1. Copy ```parity/scripts/parity.service``` to your
systemd user directory (usually ```~/.config/systemd/user```).
2. To pass any argument to Parity, write a ```~/.parity/parity.conf``` file this way:
```ARGS="ARG1 ARG2 ARG3"```.

# Parity Dapps (JS-glue)
Code generator to simplify creating a built-in Parity Dapp
# How to create new builtin Dapp.
1. Clone this repository.
```bash
$ git clone https://github.com/ethcore/parity.git
```
1. Create a new directory for your Dapp. (`./myapp`)
```bash
$ mkdir -p ./parity/dapps/myapp/src/web
```
1. Copy your frontend files to `./dapps/myapp/src/web` (bundled ones)
```bash
$ cp -r ./myapp-src/* ./parity/dapps/myapp/src/web
```
1. Instead of creating `web3` in your app. Load (as the first script tag in `head`):
```html
<script src="/parity-utils/inject.js"></script>
```
The `inject.js` script will create global `web3` instance with proper provider that should be used by your dapp.
1. Create `./parity/dapps/myapp/Cargo.toml` with you apps details. See example here: [parity-status Cargo.toml](https://github.com/ethcore/parity-ui/blob/master/status/Cargo.toml).
```bash
$ git clone https://github.com/ethcore/parity-ui.git
$ cd ./parity-ui/
$ cp ./home/Cargo.toml ../parity/dapps/myapp/Cargo.toml
$ cp ./home/build.rs ../parity/dapps/myapp/build.rs
$ cp ./home/src/lib.rs ../parity/dapps/myapp/src/lib.rs
$ cp ./home/src/lib.rs.in ../parity/dapps/myapp/src/lib.rs.in
# And edit the details of your app
$ vim ../parity/dapps/myapp/Cargo.toml # Edit the details
$ vim ./parity/dapps/myapp/src/lib.rs.in # Edit the details
```
# How to include your Dapp into `Parity`?
1. Edit `dapps/Cargo.toml` and add dependency to your application (it can be optional)
```toml
# Use git repo and version
parity-dapps-myapp = { path="./myapp" }
```
1. Edit `dapps/src/apps.rs` and add your application to `all_pages` (if it's optional you need to specify two functions - see `parity-dapps-wallet` example)
1. Compile parity.
```bash
$ cargo build --release # While inside `parity`
```
1. Commit the results.
```bash
$ git add myapp && git commit -am "My first Parity Dapp".
```
