Welcome to Syncthing’s documentation!

As a new user, the getting started guide is a good place to start, then perhaps moving on to the FAQ. If you run into trouble getting devices to connect to each other, the page about firewall setup explains the networking necessary to get it to work.

As a developer looking to get started with a contribution, see how to build, how to debug and the contribution guidelines. This documentation site can be edited on Github.
