-# DMRplus - Startup Options
-
-## Introduction
-This file is to give an overview over the Options-parameter in MMDVM.ini [DMR Network]-section.
-
-## Example
-You can pull some conection-info at startup to the DMRplus-Network to define the behavior of TS1 and TS2 in DMR-mode. 
-An example of such a line would be following:
-
-  Options=StartRef=4013;RelinkTime=15;UserLink=1;TS1_1=262;TS1_2=1;TS1_3=20;TS1_4=110;TS1_5=270;
-
-If an option is set, it overwrites the setting preset at the master, if an option is empty, it unsets a predefined setting from
-the master. If an option is not set, the default from the master would be taken over.
-
-## What the parameters are about?
-
-Here is a quick explaination about the options to be set:
-
-  * StartRef: This is the default reflector in TS2, in example: Refl. 4013
-  * RelinkTime: This is the time to fall back to the default-reflector if linked to another one and no local traffic is done, 
-  not yet implemented, would come next
-  * UserLink: This defines, if users are allowed to link to another reflector (other than defined as startreflector)
-    * 1 = allow
-    * 0 = disallow
-  * TS1_1: This is the first of 5 talkgroups that could be set static, in example: TG262
-  * TS1_2: This is the second of 5 talkgroups that could be set static, in example: TG1
-  * TS1_3: This is the third of 5 talkgroups that could be set static, in example: TG20
-  * TS1_4: This is the fourth of 5 talkgroups that could be set static, in example: TG110
-  * TS1_5: This is the fifth of 5 talkgroups that could be set static, in example: TG270
