+
+The first official release of WebTorrent Desktop, the streaming torrent client for OS X,
+Windows, and Linux. For now, we're only releasing binaries for OS X.
+
+WebTorrent Desktop is in ALPHA and under very active development – expect lots more polish in
+the coming weeks! If you know JavaScript and want to help us out, there's
+[lots to do](https://github.com/webtorrent/webtorrent-desktop/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+contribution%22)!
+
+### Features
+
+- **Lightweight, fast torrent client**
+- **Beautiful user experience**
+- **Instantly stream video and audio** from torrents!
+  - WebTorrent fetches file pieces from the network **on-demand**, for instant playback.
+  - Even when the file is not fully downloaded, **seeking still works!** (Seeking just reprioritizes what pieces are fetched from the network.)
+- Stream videos to **AirPlay** and **Chromecast**
+- **Pure Javascript**, so it's very easy to contribute code!
+- Based on the most popular and comprehensive torrent package in Node.js, [`webtorrent`](https://www.npmjs.com/package/webtorrent).
+- Lots of **features**, without the bloat:
+  - Opens magnet links and .torrent files
+  - Drag-and-drop makes adding torrents easy!
+  - Seed files/folders by dragging them onto the app
+  - Discovers peers via tracker servers, DHT (Distributed Hash Table), and peer exchange
+  - Make the video window "float on top" for watching video while you work!
+  - Supports WebTorrent protocol – for connecting to WebRTC peers (i.e. web browsers)

+
+- Use [Homebrew-Cask](https://github.com/caskroom/homebrew-cask) to install from the command line:
+
+  ```
+  $ brew install --cask webtorrent
+  ```
+
+- Try the (unstable) development version by cloning the Git repository. See the

 ## How to Contribute
 
-### Install dependencies
+### Get the code
 
 ```
+$ git clone https://github.com/webtorrent/webtorrent-desktop.git
+$ cd webtorrent-desktop
 $ npm install
 ```
 
-### Run app
+### Run the app
 
 ```
 $ npm start
 ```
 
-### Package app
+### Watch the code
 
-Builds app binaries for OS X, Linux, and Windows.
+Restart the app automatically every time code changes. Useful during development.
+
+```
+$ npm run watch
+```
+
+### Run linters
+
+```
+$ npm test
+```
+
+### Run integration tests
+
+```
+$ npm run test-integration
+```
+
+The integration tests use Spectron and Tape. They click through the app, taking screenshots and
+comparing each one to a reference. Why screenshots?
+
+* Ad-hoc checking makes the tests a lot more work to write
+* Even diffing the whole HTML is not as thorough as screenshot diffing. For example, it wouldn't
+  catch an bug where hitting ESC from a video doesn't correctly restore window size.
+* Chrome's own integration tests use screenshot diffing iirc
+* Small UI changes will break a few tests, but the fix is as easy as deleting the offending
+  screenshots and running the tests, which will recreate them with the new look.
+* The resulting Github PR will then show, pixel by pixel, the exact UI changes that were made! See
+  https://github.com/blog/817-behold-image-view-modes
+
+For MacOS, you'll need a Retina screen for the integration tests to pass. Your screen should have
+the same resolution as a 2018 MacBook Pro 13".
+
+For Windows, you'll need Windows 10 with a 1366x768 screen.
+
+When running integration tests, keep the mouse on the edge of the screen and don't touch the mouse
+or keyboard while the tests are running.

+#### Mac build notes
+
+The Mac app can only be packaged from **macOS**.
+
+#### Linux build notes
+
+The Linux app can be packaged from **any** platform.
+
+If packaging from Mac, install system dependencies with Homebrew by running:
+
+```
+npm run install-system-deps
+```
+#### Recommended readings to start working in the app
+
+Electron (Framework to make native apps for Windows, OSX and Linux in Javascript):
+https://electronjs.org/docs/tutorial/quick-start
+
+React.js (Framework to work with Frontend UI):
+https://reactjs.org/docs/getting-started.html
+
+Material UI (React components that implement Google's Material Design.):
+https://material-ui.com/getting-started/installation
+
+### Privacy
+
+WebTorrent Desktop collects some basic usage stats to help us make the app better.
+For example, we track how well the play button works. How often does it succeed?
+Time out? Show a missing codec error?
+
+The app never sends any personally identifying information, nor does it track which
+torrents you add.

+## Release Process
+
+### 1. Create a new version
+
+- Update `AUTHORS`
+
+  ```
+  npm run update-authors
+  ```
+
+  Commit if necessary. The commit message should be "authors".
+
+- Write the changelog
+
+  You can use `git log --oneline <last version tag>..HEAD` to get a list of changes.
+
+  Summarize them concisely in `CHANGELOG.md`. The commit  message should be "changelog".
+
+- Update the version
+
+  ```
+  npm version [major|minor|patch]
+  ```
+
+  This creates both a commit and a git tag.
+
+- Make a PR
+
+  Once the PR is reviewed, merge it:
+
+  ```
+  git push origin <branch-name>:master
+  ```
+
+  This makes it so that the commit hash on master matches the commit hash of the version tag.
+
+  Finally, run:
+
+  ```
+  git push --tags
+  ```
+
+### 2. Create the release binaries
+
+- On a Mac:
+
+  ```
+  npm run package -- darwin --sign
+  ```
+
+  Move the `.zip` and `.dmg` file somewhere because the next step wipes the `dist/` folder away.
+
+  ```
+  npm run package -- linux --sign
+  ```
+
+- On Windows, or in a Windows VM:
+
+  ```
+  npm run package -- win32 --sign
+  ```
+
+- Then, upload the release binaries to Github:
+
+  ```
+  npm run gh-release
+  ```
+
+  Follow the URL to a newly created Github release page. Manually upload the binaries from
+  `webtorrent-desktop/dist/`. Open the previous release in another tab, and make sure that you
+  are uploading the same set of files, no more, no less.
+
+### 3. Test it
+
+**This is the most important part.**
+
+- Manually download the binaries for each platform from Github.
+
+  **Do not use your locally built binaries.** Modern OSs treat executables differently if they've
+  been downloaded, even though the files are byte for byte identical. This ensures that the
+  codesigning worked and is valid.
+
+- Smoke test WebTorrent Desktop on each platform. Before a release, check that the following basic use cases work correctly:
+
+  1. Click "Play" to stream a built-in torrent (e.g. Sintel)
+    - Ensure that seeking to undownloaded region works and plays immediately.
+    - Ensure that sintel.mp4 gets downloaded to `~/Downloads`.
+
+  2. Check that the auto-updater works
+    - Open the console and check for the line "No update available" to indicate that the auto-updater is working. (If the auto updater does not run, users will successfully auto update to this new version, and then be stuck there forever.)
+
+  3. Add a new .torrent file via drag-and-drop.
+    - Ensure that it gets added to the list and starts downloading.
+
+  4. Remove a torrent from the client
+    - Ensure that the file is removed from `~/Downloads`
+
+  5. Create and seed a new a torrent via drag-and-drop.
+    - Ensure that the torrent gets created and seeding begins.
+
+### 4. Ship it
+
+- Update the website
+
+  Create a pull request in [webtorrent.io](https://github.com/webtorrent/webtorrent.io). Update
+  `config.js`, updating the desktop app version.
+
+  Once this PR is merged and Feross redeploys the WebTorrent website,
+  hundreds of thousands of users around the world will start auto updating. **Merge with care.**
