Add right type to transmission-vpn.service

README.md

@@ -7,20 +7,28 @@ The idea is to provide the following features, chosen at install:
 * a web interface for file management with [File Browser](https://github.com/filebrowser/filebrowser);
 * a DLNA server with MiniDLNA;
 * a BitTorrent client with Transmission, which comes with a server web interface;
-* an VPN client with OpenVPN;
+* a VPN client with OpenVPN;
 * a FTP server with vsftpd.
 In addition, Nginx is used to provide HTTPS proxy to File Browser and Transmission
 
 ### Requirements
 The following list of packages must be installed manually (depending on which features are needed):
-```transmission-daemon minidlna openvpn nginx```
+```transmission-daemon minidlna openvpn nginx vsftpd```
 File Browser must be installed manually at `/usr/local/bin/filebrowser`.
 
 A "NAS user" should be defined, owner of the NAS root directory: This user shall run some of above services.
 
+If using Transmission, you need to set an OpenVPN connection config as `vpn`.
+
+### File Browser init
+If using File Browser, it should be initiated first:
+```
+sudo -u <nas-user> filebrowser -d <nas>/filebrowser.db --username <admin>
+```
+
 ### Files
 * `transmission-vpn.sh` is a script which checks if a VPN connection is active and stops Transmission otherwise.
-* `variables.conf.template` contains examples variables definitions, and should be copied locally to `variables.conf`
+* `variables.conf.template` contains examples of variables definitions, and should be copied locally to `variables.conf`
   (with any required modifications).
 * `systemd-templates/` contains Systemd units templates for all the services.
 * `nginx-blocks/` contains Nginx configuration blocks.
