+### Dependencies ###
+
+* Ruby >= 1.9
+* ruby-sqlite3 >= 1.3
+* xmpp4r == 0.5.6
+* tdlib-ruby == 2.0 with pre-compiled _libtdjson.so_
+
+(there is pre-compiled _libtdjson.so_ for Debian Stretch x64 in repository)
+
+### Installation ###
+
+First of all, you need to create component listener on your Jabber server. 
+For example, for ejabberd:
+
+```port: 8888  
+module: ejabberd_service  
+access: all  
+shaper_rule: fast  
+ip: "127.0.0.1"  
+service_check_from: false  
+hosts:  
+	"telegram.jabber.ru":  
+		password: "secret"
+```
+
+
+Next, move **config.yml.example** to and **config.yml** and edit **xmpp** section to match component listener:
+
+```
+db_path: 'users.db'  
+jid: 'telegram.jabber.ru'  
+host: 'localhost'  
+port: 8888  
+secret: 'secret'  
+loglevel: 0   
+```
+
+If neccessary, edit **telegram** section too.
