My problem is, hwo can i edit the file?

1. Extract the. zip file and save it in the machine that you want to run the PBX adapter. (This system should be able to communicate easily with your PBX system.)
2. Edit the "Zoho/ztiadapter/conf/zti.properties" file and configure the authorization key
3. Edit the "Zoho/ztiadapter/teleadapters/asterisk14/conf/asterisk14.properties" file and configure the PBX details
4. Run the nohup sh run.sh & command inside the zoho/ztiadapter/bin directory
