To stake your node click on the little person icon in the top right corner of your presearch.org.
Make sure you are logged in. 🙂
It will display a bunch of account data. You need to click on “Node Stakes”

This page will display all the nodes you have setup. Click the orange button on the right labeled “Stake”

On this page enter the amount you want to stake and name your node. You can ignore the Url. Click “Update”

You’re done. That’s all you have to do!
Click the “<<Back to node list” and it will show your staked amount next to the green connected plug.
