-# Code of Conduct
-
-## 1. Purpose
-
-A primary goal of OpenEthereum project is to be inclusive to the largest number of contributors, with the most varied and diverse backgrounds possible. As such, we are committed to providing a friendly, safe and welcoming environment for all, regardless of gender, sexual orientation, ability, ethnicity, socioeconomic status, and religion (or lack thereof).
-
-This code of conduct outlines our expectations for all those who participate in our community, as well as the consequences for unacceptable behavior.
-
-We invite all those who participate in OpenEthereum to help us create safe and positive experiences for everyone.
-
-## 2. Open Source Citizenship
-
-A supplemental goal of this Code of Conduct is to increase open source citizenship by encouraging participants to recognize and strengthen the relationships between our actions and their effects on our community.
-
-Communities mirror the societies in which they exist and positive action is essential to counteract the many forms of inequality and abuses of power that exist in society.
-
-If you see someone who is making an extra effort to ensure our community is welcoming, friendly, and encourages all participants to contribute to the fullest extent, we want to know.
-
-## 3. Expected Behavior
-
-The following behaviors are expected and requested of all community members:
-
-*   Participate in an authentic and active way. In doing so, you contribute to the health and longevity of this community.
-*   Exercise consideration and respect in your speech and actions.
-*   Attempt collaboration before conflict.
-*   Refrain from demeaning, discriminatory, or harassing behavior and speech.
-*   Be mindful of your surroundings and of your fellow participants. Alert community leaders if you notice a dangerous situation, someone in distress, or violations of this Code of Conduct, even if they seem inconsequential.
-*   Remember that community event venues may be shared with members of the public; please be respectful to all patrons of these locations.
-
-## 4. Unacceptable Behavior
-
-The following behaviors are considered harassment and are unacceptable within our community:
-
-*   Violence, threats of violence or violent language directed against another person.
-*   Sexist, racist, homophobic, transphobic, ableist or otherwise discriminatory jokes and language.
-*   Posting or displaying sexually explicit or violent material.
-*   Posting or threatening to post other people’s personally identifying information ("doxing").
-*   Personal insults, particularly those related to gender, sexual orientation, race, religion, or disability.
-*   Inappropriate photography or recording.
-*   Inappropriate physical contact. You should have someone’s consent before touching them.
-*   Unwelcome sexual attention. This includes, sexualized comments or jokes; inappropriate touching, groping, and unwelcomed sexual advances.
-*   Deliberate intimidation, stalking or following (online or in person).
-*   Advocating for, or encouraging, any of the above behavior.
-*   Sustained disruption of community events, including talks and presentations.
-
-## 5. Consequences of Unacceptable Behavior
-
-Unacceptable behavior from any community member, including sponsors and those with decision-making authority, will not be tolerated.
-
-Anyone asked to stop unacceptable behavior is expected to comply immediately.
-
-If a community member engages in unacceptable behavior, the community organizers may take any action they deem appropriate, up to and including a temporary ban or permanent expulsion from the community without warning (and without refund in the case of a paid event).
-
-## 6. Reporting Guidelines
-
-If you are subject to or witness unacceptable behavior, or have any other concerns, please notify a community organizer as soon as possible. community@parity.io.
-
-Link to reporting guidelines: [CONTRIBUTING.md](CONTRIBUTING.md)
-
-Link to security policy: [SECURITY.md](../SECURITY.md)
-
-Additionally, community organizers are available to help community members engage with local law enforcement or to otherwise help those experiencing unacceptable behavior feel safe. In the context of in-person events, organizers will also provide escorts as desired by the person experiencing distress.
-
-## 7. Addressing Grievances
-
-If you feel you have been falsely or unfairly accused of violating this Code of Conduct, you should notify Parity Technologies with a concise description of your grievance. Your grievance will be handled in accordance with our existing governing policies.
-
-## 8. Scope
-
-We expect all community participants (contributors, paid or otherwise; sponsors; and other guests) to abide by this Code of Conduct in all community venues–online and in-person–as well as in all one-on-one communications pertaining to community business.
-
-This code of conduct and its related procedures also applies to unacceptable behavior occurring outside the scope of community activities when such behavior has the potential to adversely affect the safety and well-being of community members.

-# Contributing Guidelines
-
-## Do you have a question?
-
-Check out our [Basic Usage](https://wiki.parity.io/Basic-Usage), [Configuration](https://wiki.parity.io/Configuring-Parity-Ethereum), and [FAQ](https://wiki.parity.io/FAQ) articles on our [wiki](https://wiki.parity.io/)!
-
-See also frequently asked questions [tagged with `parity`](https://ethereum.stackexchange.com/questions/tagged/parity?sort=votes&pageSize=50) on Stack Exchange.
-
-## Report bugs!
-
-Do **not** open an issue on Github if you think your discovered bug could be a **security-relevant vulnerability**. Please, read our [security policy](../SECURITY.md) instead.
-
-Otherwise, just create a [new issue](https://github.com/openethereum/openethereum/issues/new) in our repository and state:
-
-- What's your OpenEthereum version?
-- What's your operating system and version?
-- How did you install OpenEthereum?
-- Is your node fully synchronized?
-- Did you try turning it off and on again?
-
-Also, try to include **steps to reproduce** the issue and expand on the **actual versus expected behavior**.
-
-## Contribute!
-
-If you would like to contribute to OpenEthereum, please **fork it**, fix bugs or implement features, and [propose a pull request](https://github.com/openethereum/openethereum/compare).
-
-### Labels & Milestones
-
-We use [labels](https://github.com/openethereum/openethereum/labels) to manage PRs and issues and communicate the state of a PR. Please familiarize yourself with them. Furthermore we are organizing issues in [milestones](https://github.com/openethereum/openethereum/milestones). Best way to get started is to a pick a ticket from the current milestone tagged [`easy`](https://github.com/openethereum/openethereum/labels/Q2-easy%20%F0%9F%92%83) and get going, or [`mentor`](https://github.com/openethereum/openethereum/labels/Q1-mentor%20%F0%9F%95%BA) and get in contact with the mentor offering their support on that larger task.
-
-### Rules
-
-There are a few basic ground-rules for contributors (including the maintainer(s) of the project):
-
-* **No pushing directly to the master branch**.
-* **All modifications** must be made in a **pull-request** to solicit feedback from other contributors.
-* Pull-requests cannot be merged before CI runs green and two reviewers have given their approval.
-* Contributors should adhere to the [Parity Ethereum Style Guide](https://wiki.parity.io/Parity-Ethereum-Style-Guide).
-
-### Recommendations
-
-* **Non-master branch names** *should* be prefixed with a short name moniker, followed by the associated Github Issue ID (if any), and a brief description of the task using the format `<GITHUB_USERNAME>-<ISSUE_ID>-<BRIEF_DESCRIPTION>` (e.g. `gavin-123-readme`). The name moniker helps people to inquiry about their unfinished work, and the GitHub Issue ID helps your future self and other developers (particularly those who are onboarding) find out about and understand the original scope of the task, and where it fits into OpenEthereum [Projects](https://github.com/openethereum/openethereum/projects).
-* **Remove stale branches periodically**
-
-### Preparing Pull Requests
-
-* If your PR does not alter any logic (e.g. comments, dependencies, docs), then it may be tagged [`insubstantial`](https://github.com/openethereum/openethereum/pulls?q=is%3Aopen+is%3Apr+label%3A%22A2-insubstantial+%F0%9F%91%B6%22).
-
-* Once a PR is ready for review please add the [`pleasereview`](https://github.com/openethereum/openethereum/pulls?utf8=%E2%9C%93&q=is%3Aopen+is%3Apr+label%3A%22A0-pleasereview+%F0%9F%A4%93%22+) label.
-
-### Reviewing Pull Requests*:
-
-* At least two reviewers are required to review PRs (even for PRs tagged [`insubstantial`](https://github.com/openethereum/openethereum/pulls?q=is%3Aopen+is%3Apr+label%3A%22A2-insubstantial+%F0%9F%91%B6%22)).
-
-When doing a review, make sure to look for any:
-
-* Buggy behavior.
-* Undue maintenance burden.
-* Breaking with house coding style.
-* Pessimization (i.e. reduction of speed as measured in the projects benchmarks).
-* Breaking changes should be carefuly reviewed and tagged as such so they end up in the [changelog](../CHANGELOG.md).
-* Uselessness (i.e. it does not strictly add a feature or fix a known issue).
-
-## License.
-
-By contributing to OpenEthereum, you agree that your contributions will be licensed under the [GPLv3 License](../LICENSE).

-## OpenEthereum [v3.0.1](https://github.com/openethereum/openethereum/releases/tag/v3.0.1)
+## Parity [v1.7.3](https://github.com/paritytech/parity/releases/tag/v1.7.3) (2017-10-09)
 
-- Add missing forks to fork ID (#11747)
+Parity 1.7.3 enables the Byzantium fork for Ethereum main network on Block 4_370_000 and offers a variety of bug fixes and stability improvements. Among them:
 
-## OpenEthereum [v3.0.0](https://github.com/openethereum/openethereum/releases/tag/v3.0.0)
+- Fixed network protocol version negotiation with Geth nodes v1.7.1+.
+- Fixed `RETURNDATA` size for built-ins. (Built-ins in some cases overwrite only a portion of the output memory slice.)
+- Multisig Wallet View now loads if multiple transactions happened within one block.
+- Improved stability of snapshot-sycns (warp).
+- Revised timeout and batch size constants for bigger blocks.
+- Renamed RPC receipt `statusCode` field to `status`.
 
-OpenEthereum v3.0.0 is the first release of OpenEthereum client as part of OpenEthereum project, divested from Parity Technologies.
+Full list of included changes:
 
-This release marks the transition from Parity Technologies infrastructure and bootnodes to the one managed by OpenEthereum project.
+- Backporting ([#6676](https://github.com/paritytech/parity/pull/6676))
+  - Fix wallet view ([#6597](https://github.com/paritytech/parity/pull/6597))
+    - Add safe fail for empty logs
+    - Filter transactions
+    - Add more logging
+    - Fix Wallet Creation and wallet tx list

+    - Fix tests
+    - Remove unused props
+  - Disallow pasting recovery phrases on first run ([#6602](https://github.com/paritytech/parity/pull/6602))
+    - Fix disallowing paste of recovery phrase on first run, ref [#6581](https://github.com/paritytech/parity/issues/6581)
+    - Allow the leader of CATS pasting recovery phrases.
+  - Updated systemd files for linux ([#6592](https://github.com/paritytech/parity/pull/6592))
+    - Previous version put $BASE directory in root directory.
+    - This version clearly explains how to run as root or as specific user.
+    - Additional configuration:
+      - send SIGHUP for clean exit,
+      - restart on fail.
+    - Tested on Ubuntu 16.04.3 LTS with 4.10.0-33-generic x86_64 kernel
+  - Don't expose port 80 for parity anymore ([#6633](https://github.com/paritytech/parity/pull/6633))
+- Backporting ([#6675](https://github.com/paritytech/parity/pull/6675))
+  - Required validators >= num owners ([#6551](https://github.com/paritytech/parity/pull/6551))
+  - Debounce sync status. ([#6572](https://github.com/paritytech/parity/pull/6572))
+  - Fixed network protocol version negotiation ([#6649](https://github.com/paritytech/parity/pull/6649))
+  - Renamed RPC receipt statusCode field to status ([#6650](https://github.com/paritytech/parity/pull/6650))
+  - Fixed RETURNDATA size for built-ins ([#6652](https://github.com/paritytech/parity/pull/6652))
+- Byzantium fork block number ([#6661](https://github.com/paritytech/parity/pull/6661))
+- Refreshing block number on status view ([#6610](https://github.com/paritytech/parity/pull/6610))
+- Tweaked block download timeouts ([#6595](https://github.com/paritytech/parity/pull/6595))
+- Backports ([#6563](https://github.com/paritytech/parity/pull/6563))
+  - Sync progress and error handling fixes ([#6560](https://github.com/paritytech/parity/pull/6560))
+  - Fixed receipt serialization and RPC ([#6555](https://github.com/paritytech/parity/pull/6555))
+- Bump to v1.7.3
 
-Parity-Ethereum v2.7 users can continue using their existing data folders. Command-line interface has also stayed identical.
-Unless specified otherwise, OpenEthereum v3.0.0 will detect if the user's database in the old Parity-Ethereum default path,
-and only if it's not found will write to the new default location.
+## Parity [v1.7.2](https://github.com/paritytech/parity/releases/tag/v1.7.2) (2017-09-18)
 
-This release includes several major improvements to network and database stack:
-- Support for `eth/64` protocol and Node Discovery v4 `Ethereum Node Records` extension.
-- Accounts bloom is removed which should decrease the database size.
+Parity 1.7.2 is a bug-fix release to improve performance and stability. Among others, it addresses the following:
 
-**Due to database changes this is a one-way upgrade. Please back up your database if you plan to continue using Parity-Ethereum v2.7.2.**
+- Byzantium fork support for the Ropsten and Foundation networks.
+- Added support for the ConsenSys and Gnosis multi-signature wallets.
+- Significantly increased token registry and token balance lookup performance.
+- Fixed issues with the health status indicator in the wallet.
+- Tweaked warp-sync to quickly catch up with chains fallen back more than 10,000 blocks.
+- Fixes to the Chrome extension and macOS installer upgrades.
 
-Note that this release drops support for IPFS and `eth/62` protocol. Additionally, it marks light client, private transactions and updater as deprecated features which may be removed in a future release.

+## Parity [v1.7.0](https://github.com/paritytech/parity/releases/tag/v1.7.0) (2017-07-28)
+
+Parity 1.7.0 is a major release introducing several important features:
+
+- **Experimental [Light client](https://github.com/paritytech/parity/wiki/The-Parity-Light-Protocol-(PIP)) support**. Start Parity with `--light` to enable light mode. Please, note: The wallet UI integration for the light client is not included, yet.
+- **Experimental web wallet**. A hosted version of Parity that keeps the keys and signs transactions using your browser storage. Try it at https://wallet.parity.io or run your own with `--public-node`.
+- **WASM contract support**. Private networks can run contracts compiled into WASM bytecode. _More information and documentation to follow_.
+- **DApps and RPC server merge**. DApp and RPC are now available through a single API endpoint. DApp server related settings are deprecated.
+- **Export accounts from the wallet**. Backing up your keys can now simply be managed through the wallet interface.
+- **PoA/Kovan validator set contract**. The PoA network validator-set management via smart contract is now supported by warp and, in the near future, light sync.
+- **PubSub API**. https://github.com/paritytech/parity/wiki/JSONRPC-Parity-Pub-Sub-module
+- **Signer apps for IOS and Android**.
+

+## About Parity
 
-## 1. Description <a id="chapter-001"></a>
+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.
 
-**Built for mission-critical use**: Miners, service providers, and exchanges need fast synchronisation and maximum uptime. OpenEthereum provides the core infrastructure essential for speedy and reliable services.
+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:
 
-- Clean, modular codebase for easy customisation
-- Advanced CLI-based client
-- Minimal memory and storage footprint
-- Synchronise in hours, not days with Warp Sync
-- Modular for light integration into your service or product
+- create and manage your Ethereum accounts;
+- manage your Ether and any Ethereum tokens;
+- create and register your own tokens;
+- and much more.
 
-## 2. Technical Overview <a id="chapter-002"></a>
+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.
 
-OpenEthereum's goal is to be the fastest, lightest, and most secure Ethereum client. We are developing OpenEthereum using the **Rust programming language**. OpenEthereum is licensed under the GPLv3 and can be used for all your Ethereum needs.
+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!
 
-By default, OpenEthereum runs a JSON-RPC HTTP server on port `:8545` and a Web-Sockets server on port `:8546`. This is fully configurable and supports a number of APIs.
+**For security-critical issues**, please refer to the security policy outlined in `SECURITY.MD`.
 
-If you run into problems while using OpenEthereum, check out the [old wiki for documentation](https://wiki.parity.io/), feel free to [file an issue in this repository](https://github.com/openethereum/openethereum/issues/new), or hop on our [Discord](https://discord.io/openethereum) chat room to ask a question. We are glad to help!

+## Build dependencies
 
-### 3.1 Build Dependencies <a id="chapter-0031"></a>
+**Parity requires Rust version 1.19.0 to build**
 
-OpenEthereum requires **latest stable Rust version** 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:
+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
-  ```
-
-  OpenEthereum also requires `clang` (>= 9.0), `clang++`, `pkg-config`, `file`, `make`, and `cmake` packages to be installed.
+	```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
-  ```
+	```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:
-  ```bash
-  $ rustup default stable-x86_64-pc-windows-msvc
-  ```

-Once you have `rustup` installed, then you need to install:
-* [Perl](https://www.perl.org)
-* [Yasm](https://yasm.tortall.net)
+Once you have rustup, install parity or download and build from source
 
-Make sure that these binaries are in your `PATH`. After that, you should be able to build OpenEthereum from source.

-### 3.2 Build from Source Code <a id="chapter-0032"></a>
+## Install from the snap store
+
+In any of the [supported Linux distros](https://snapcraft.io/docs/core/install):
 
 ```bash
-# download OpenEthereum code
-$ git clone https://github.com/openethereum/openethereum
-$ cd openethereum
-
-# build in release mode
-$ cargo build --release --features final
+sudo snap install parity --edge
 ```
 
-This produces an executable in the `./target/release` subdirectory.
+(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
 ```
+----
 
-Note, when compiling a crate and you receive errors, it's in most cases your outdated version of Rust, or some of your crates have to be recompiled. Cleaning the repository will most likely solve the issue if you are on the latest stable version of Rust, try:
+## Simple one-line installer for Mac and Ubuntu
 
 ```bash
-$ cargo clean
+bash <(curl https://get.parity.io -Lk)
 ```
 
-This always compiles the latest nightly builds. If you want to build stable, do a
-
+## Start Parity
+### Manually
+To start Parity manually, just run
 ```bash
-$ git checkout stable
+$ ./target/release/parity
 ```
 
-### 3.3 Starting OpenEthereum <a id="chapter-0034"></a>
+and Parity will begin syncing the Ethereum blockchain.
 
-#### Manually
+### Using systemd service file
+To start Parity as a regular user using systemd init:
 
-To start OpenEthereum manually, just run
+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"`.
 
-```bash
-$ ./target/release/openethereum
-```
-
-so OpenEthereum begins syncing the Ethereum blockchain.
-
-#### Using `systemd` service file
-
-To start OpenEthereum as a regular user using `systemd` init:
-
-1. Copy `./scripts/openethereum.service` to your
-`systemd` user directory (usually `~/.config/systemd/user`).
-2. Copy release to bin folder, write `sudo install ./target/release/openethereum /usr/bin/openethereum`
-3. To configure OpenEthereum, see [our old wiki](https://paritytech.github.io/wiki/Configuring-Parity) for details.
-
-## 4. Testing <a id="chapter-004"></a>
-
-Download the required test files: `git submodule update --init --recursive`. You can run tests with the following commands:
-
-* **All** packages
-  ```
-  cargo test --all
-  ```
-
-* Specific package
-  ```
-  cargo test --package <spec>
-  ```
-
-Replace `<spec>` with one of the packages from the [package list](#package-list) (e.g. `cargo test --package evmbin`).
-
-You can show your logs in the test output by passing `--nocapture` (i.e. `cargo test --package evmbin -- --nocapture`)
-
-## 5. Documentation <a id="chapter-005"></a>
-
-Be sure to [check out our old wiki](https://wiki.parity.io) for more information.
-
-### Viewing documentation for OpenEthereum packages
-
-You can generate documentation for OpenEthereum Rust packages that automatically opens in your web browser using [rustdoc with Cargo](https://doc.rust-lang.org/rustdoc/what-is-rustdoc.html#using-rustdoc-with-cargo) (of the The Rustdoc Book), by running the the following commands:
-
-* **All** packages
-  ```
-  cargo doc --document-private-items --open
-  ```
-
-* Specific package
-  ```
-  cargo doc --package <spec> -- --document-private-items --open
-  ```
-
-Use`--document-private-items` to also view private documentation and `--no-deps` to exclude building documentation for dependencies.
-
-Replacing `<spec>` with one of the following from the details section below (i.e. `cargo doc --package openethereum --open`):

-OpenEthereum keys generator.
-  Copyright 2015-2020 Parity Technologies (UK) Ltd.
-
-Usage:
-    ethkey info <secret-or-phrase> [options]
-    ethkey generate random [options]
-    ethkey generate prefix <prefix> [options]
-    ethkey sign <secret> <message>
-    ethkey verify public <public> <signature> <message>
-    ethkey verify address <address> <signature> <message>
-    ethkey recover <address> <known-phrase>
-    ethkey [-h | --help]
-
-Options:
-    -h, --help         Display this message and exit.
-    -s, --secret       Display only the secret key.
-    -p, --public       Display only the public key.
-    -a, --address      Display only the address.
-    -b, --brain        Use parity brain wallet algorithm. Not recommended.
-
-Commands:
-    info               Display public key and address of the secret.
-    generate random    Generates new random Ethereum key.
-    generate prefix    Random generation, but address must start with a prefix ("vanity address").
-    sign               Sign message using a secret key.
-    verify             Verify signer of the signature by public key or address.
-    recover            Try to find brain phrase matching given address from partial phrase.

+# 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/paritytech/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/paritytech/parity-ui/blob/master/status/Cargo.toml).
+
+   ```bash
+   $ git clone https://github.com/paritytech/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".
+   ```
