+
 ## `Installation`
+
 ### `Requirements`
+
 Cameras settings:
+>
 > - Configuration -> System -> Security -> Authentication -> RTSP Authentication: digest/basic
 > - Configuration -> System -> Security -> Authentication -> WEB Authentication: digest/basic
 > - Configuration -> Network -> Advanced Settings -> Integration Protocol -> Enable Hikvision-CGI: Enabled
 > - Configuration -> Network -> Advanced Settings -> Integration Protocol -> Hikvision-CGI Authentication: digest/basic

 Look at the description of dependencies and install the necessary.
+
 ### `Downloading`
+
 Download scripts and configs.
+
 ```bash
 wget https://git.hmp.today/pavel.muhortov/cctv-scheduler/raw/branch/master/sequences.sh -O /home/user/cctv-scheduler/sequences.sh
