+**Parity requires Rust version 1.12.0 to build**
 
-### Building from source
+----
 
-First (if you don't already have it) get multirust:
 
-- Linux:
+## 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://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.    
+
+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's current release is 1.3. You can download it at https://ethcore.io/parity.html or follow the instructions
+below to build from source.
+
+----
+
+## Build dependencies
+
+Parity is fully compatible with Stable Rust.
+
+We recommend installing Rust through [rustup](https://www.rustup.rs/). If you don't already have rustup, you can install it like this:
+
+- Linux and OSX:
+	```bash
+	$ curl https://sh.rustup.rs -sSf | sh
+	```
+
+- 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
+
+----
+
+## Quick install
+
 ```bash
-curl -sf https://raw.githubusercontent.com/brson/multirust/master/quick-install.sh | sudo sh -s -- --yes
+cargo install --git https://github.com/ethcore/parity.git parity
 ```
 
-- OSX with Homebrew:
-```bash
-brew update && brew install multirust
-```
+----
 
-Then, download and build Parity:
+## Build from source
 
 ```bash
 # download Parity code
-git clone https://github.com/ethcore/parity
-cd parity
+$ git clone https://github.com/ethcore/parity
+$ cd parity
 
 # build in release mode
-cargo build --release
+$ cargo build --release
 ```
+
+This will produce an executable in the `./target/release` subdirectory.
+
+## 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 --geth --identity MyMachine"`.

+# 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".
+   ```
