   8 ## 1. Summary
   9
  10 Syncthing is a decentralized file-synchronization program that permits
  11 sharing of files over the Internet with computers that have been
  12 configured to trust one another.
  13
  14 ## 2. Instructions
  15
  16 The following are instructions for installing Syncthing onto a GNU/Linux Debian 10 machine.
  17
  18 ### 2.1. Install `syncthing` via `apt-get`
  19
  20 Update the local repository package lists with `$ sudo apt-get update`.
  21
  22 Install the `syncthing` package with `$ sudo apt-get install syncthing`.
  23
  24 Note: As of 2020-04-27, Debian 10 Buster uses Syncthing version `1.0.0`.
  25
  26 ### 2.2. Enable automatic startup via `systemd` service.
  27
  28 Syncthing can be started automatically via `systemd` as a system
  29 service upon boot or a user service upon login. If `syncthing` was
  30 installed from the Debian 10 repository (ex: via `apt-get`), then the
  31 necessary service files (ex: `syncthing@.service` ) should already be
  32 installed. If not, see the detailed autostart instructions for where
  33 to download a copy of the service
  34 files.<sup>[[1]](#syncthing_20200331_autostart)</sup>
  35
  36 #### 2.2.a. Enable automatic startup via `systemd` upon boot (system service).
  37
  38 For a system service, identify the user under which to run
  39 `syncthing`. Even though `syncthing` will be run upon startup (without
  40 needing a user to login first), files cannot be created or modified by
  41 `syncthing` with permissions of a specified user. In this example,
  42 `baltakatei` will be the user. This means an appropriate directory for
  43 a `syncthing` shared folder would be `/home/baltakatei/Sync/`.
  44
  45 Alternatively, if `syncthing` were running as a headless server where
  46 no user is expected to directly modify files in the server's file
  47 system, then a dedicated dummy user named `syncthing-user` might be
  48 appropriate.
  49
  50 The commands to create a `systemd` system service under user
  51 `baltakatei` are:
  52
  53     $ sudo systemctl enable syncthing@baltakatei.service
  54         $ sudo systemctl start syncthing@baltakatei.service
  55
  56 The status of the new system service can be verified via:
  57
  58     $ systemctl status syncthing@baltakatei.service
  59
  60 #### 2.2.b. Enable automatic startup via `systemd` upon login (user service).
  61
  62 For a user service, identify which user under which to run
  63 `syncthing`. In this example, `baltakatei` will be the user. This
  64 means an appropriate directory for a `syncthing` shared folder would
  65 be `/home/baltakatei/Sync/`.
  66
  67 The commands to create a `systemd` user service under user
  68 `baltakatei` are:
  69
  70     $ systemctl --user enable syncthing.service
  71         $ systemctl --user start syncthing.service
  72
  73 The status of the new user service can be verified via:
  74
  75     $ systemctl --user status syncthing.service
