+
+## 1. Summary
+
+Syncthing is a decentralized file-synchronization program that permits
+sharing of files over the Internet with computers that have been
+configured to trust one another.
+
+## 2. Instructions
+
+The following are instructions for installing Syncthing onto a GNU/Linux Debian 10 machine.
+
+### 2.1. Install `syncthing` via `apt-get`
+
+Update the local repository package lists with `$ sudo apt-get update`.
+
+Install the `syncthing` package with `$ sudo apt-get install syncthing`.
+
+Note: As of 2020-04-27, Debian 10 Buster uses Syncthing version `1.0.0`.
+
+### 2.2. Enable automatic startup via `systemd` service.
+
+Syncthing can be started automatically via `systemd` as a system
+service upon boot or a user service upon login. If `syncthing` was
+installed from the Debian 10 repository (ex: via `apt-get`), then the
+necessary service files (ex: `syncthing@.service` ) should already be
+installed. If not, see the detailed autostart instructions for where
+to download a copy of the service
+files.<sup>[[1]](#syncthing_20200331_autostart)</sup>
+
+#### 2.2.a. Enable automatic startup via `systemd` upon boot (system service).
+
+For a system service, identify the user under which to run
+`syncthing`. Even though `syncthing` will be run upon startup (without
+needing a user to login first), files cannot be created or modified by
+`syncthing` with permissions of a specified user. In this example,
+`baltakatei` will be the user. This means an appropriate directory for
+a `syncthing` shared folder would be `/home/baltakatei/Sync/`.
+
+Alternatively, if `syncthing` were running as a headless server where
+no user is expected to directly modify files in the server's file
+system, then a dedicated dummy user named `syncthing-user` might be
+appropriate.
+
+The commands to create a `systemd` system service under user
+`baltakatei` are:
+
+ $ sudo systemctl enable syncthing@baltakatei.service
+ $ sudo systemctl start syncthing@baltakatei.service
+
+The status of the new system service can be verified via:
+
+ $ systemctl status syncthing@baltakatei.service
+
+#### 2.2.b. Enable automatic startup via `systemd` upon login (user service).
+
+For a user service, identify which user under which to run
+`syncthing`. In this example, `baltakatei` will be the user. This
+means an appropriate directory for a `syncthing` shared folder would
+be `/home/baltakatei/Sync/`.
+
+The commands to create a `systemd` user service under user
+`baltakatei` are:
+
+ $ systemctl --user enable syncthing.service
+ $ systemctl --user start syncthing.service
+
+The status of the new user service can be verified via:
+
+ $ systemctl --user status syncthing.service
