[Sync Config File Read Only, Overwrite_Changes]

I have some folders I want to sync in read only mode. There are two things I seek to understand.

 

1. read only secret and read write secret

2. overwrite_changes option

 

I have 4 systems these folders will be synced between. 1 (master) 3 (slaves). If a changes is made to a file on a slave I want it to be reverted to the origional on the next sync interval. Everything will be running on a headless system so i'm using the btsync.conf file. The master is a linux os, the 3 slaves are windows os.

 

I have setup two seperate config files one for the server, and one for the slaves. 

 

Q1: Where do I put ("overwrite_changes" : true,)  in the client config or server config?

Q2: When setting up the server config file do I need both the read write and read only secrets in the shared folders section or can I just have the read only secret there?

 

Here are examples config files

 

Master:

{
  "device_name" : "Master sync",
  "listening_port" : 1234,
  "storage_path" : "/home/btsync",
  "folder_rescan_interval": 60,

  "check_for_updates" : false,
  "use_upnp" : false,

  "shared_folders": [
        {
   "secret" : "ReadWrite",
   "secret" : "ReadOnly",
            "dir" : "/home/btsync/folder_A",
