 ## Opt-In HPFEEDS Data Submission
-As an Opt-In it is now possible to also share T-Pot data with 3rd party HPFEEDS brokers, such as [SISSDEN](https://sissden.eu).
-If you want to share your T-Pot data you simply have to register an account with a 3rd party broker with its own benefits towards the community. Once registered you will receive your credentials to share events with the broker. In T-Pot you simply run `hpfeeds_optin.sh` which will ask for your credentials, in case of SISSDEN this is just `Ident` and `Secret`, everything else is pre-configured. It will automatically update `/opt/tpot/etc/tpot.yml` to deliver events to your desired broker.

+
+Your current config will also be stored in `/data/ews/conf/hpfeeds.cfg` where you can review or change it.  
+No worries: You old config is backed up in `/data/ews/conf/hpfeeds.cfg.old`  
+Be sure to apply any changes by running `./hpfeeds_optin.sh --conf=/data/ews/conf/hpfeeds.cfg`.
+
+Of course you can also rerun the `hpfeeds_optin.sh` to change and apply your settings interactively.
