## 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.
Parity comes with a built-in wallet. To access [Parity Wallet](http://web3.site/) simply go to http://web3.site/ (if you don't have access to the internet, but still want to use the service, you can also use http://127.0.0.1:8180/). 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.
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](https://gitter.im/paritytech/parity) to ask a question. We are glad to help!
**For security-critical issues**, please refer to the security policy outlined in `SECURITY.MD`.
Parity's current beta-release is 1.7. You can download it at https://github.com/paritytech/parity/releases or follow the instructions below to build from source.
----
## Build dependencies
**Parity 1.7.x-beta requires Rust version 1.19.0 to build**.
We recommend installing Rust through [rustup](https://www.rustup.rs/). If you don't already have rustup, you can install it like this:
- Linux:
```bash
$ curl https://sh.rustup.rs -sSf | sh
```
Parity also requires `gcc`, `g++`, `libssl-dev`/`openssl`, `libudev-dev` and `pkg-config` packages to be installed.
- OSX:
```bash
$ curl https://sh.rustup.rs -sSf | sh
```
`clang` is required. It comes with Xcode command line tools or can be installed with homebrew.
- Windows
Make sure you have Visual Studio 2015 with C++ support installed. Next, download and run the rustup installer from
https://static.rust-lang.org/rustup/dist/x86_64-pc-windows-msvc/rustup-init.exe, start "VS2015 x64 Native Tools Command Prompt", and use the following command to install and set up the msvc toolchain:
```
$ rustup default stable-x86_64-pc-windows-msvc
```
Once you have rustup, install parity or download and build from source
----
## Install from the snap store
In any of the [supported Linux distros](https://snapcraft.io/docs/core/install):
```bash
sudo snap install parity --edge
```
(Note that this is an experimental and unstable release, at the moment)
----
## Build from source
```bash
# download Parity code
$ git clone https://github.com/paritytech/parity
$ cd parity
# build in release mode
$ cargo build --release
```
This will produce an executable in the `./target/release` subdirectory.
Note: if cargo fails to parse manifest try:
```bash
$ ~/.cargo/bin/cargo build --release
```
----
## Simple one-line installer for Mac and Ubuntu
```bash
bash <(curl https://get.parity.io -Lk)
```
## Start Parity
### Manually
To start Parity manually, just run
```bash
$ ./target/release/parity
```
and Parity will begin syncing the Ethereum blockchain.
### 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"`.
Example: `ARGS="ui --identity MyMachine"`.
