# Syncthing [![Latest Build (Official)](https://img.shields.io/jenkins/s/http/build.syncthing.net/syncthing.svg?style=flat-square&label=unix%20build)](http://build.syncthing.net/job/syncthing/lastBuild/) [![API Documentation](https://img.shields.io/badge/api-Godoc-blue.svg?style=flat-square)](http://godoc.org/github.com/syncthing/syncthing) [![MPLv2 License](https://img.shields.io/badge/license-MPLv2-blue.svg?style=flat-square)](https://www.mozilla.org/MPL/2.0/) [![CII Best Practices](https://bestpractices.coreinfrastructure.org/projects/88/badge)](https://bestpractices.coreinfrastructure.org/projects/88) This is the Syncthing project which pursues the following goals: 1. Define a protocol for synchronization of a folder between a number of collaborating devices. This protocol should be well defined, unambiguous, easily understood, free to use, efficient, secure and language neutral. This is called the [Block Exchange Protocol][1]. 2. Provide the reference implementation to demonstrate the usability of said protocol. This is the `syncthing` utility. We hope that alternative, compatible implementations of the protocol will arise. The two are evolving together; the protocol is not to be considered stable until Syncthing 1.0 is released, at which point it is locked down for incompatible changes. ## Getting Started Take a look at the [getting started guide][2]. There are a few examples for keeping Syncthing running in the background on your system in [the etc directory][3]. There are also several [GUI implementations][11] for Windows, Mac and Linux. ## Vote on features/bugs We'd like to encourage you to [vote][12] on issues that matter to you. This helps the team understand what are the biggest pain points for our users, and could potentially influence what is being worked on next. ## Getting in Touch The first and best point of contact is the [Forum][8]. There is also an IRC channel, `#syncthing` on [freenode][4] (with a [web client][9]), for talking directly to developers and users. If you've found something that is clearly a bug, feel free to report it in the [GitHub issue tracker][10]. ## Building Building Syncthing from source is easy, and there's a [guide][5] that describes it for both Unix and Windows systems. ## Signed Releases As of v0.10.15 and onwards release binaries are GPG signed with the key D26E6ED000654A3E, available from https://syncthing.net/security.html and most key servers. There is also a built in automatic upgrade mechanism (disabled in some distribution channels) which uses a compiled in ECDSA signature. Mac OS X binaries are also properly code signed. ## Documentation Please see the [Syncthing documentation site][6]. All code is licensed under the [MPLv2 License][7].
