Searching through posts (use ecency search bar for example), you can find lots of good ones. Some examples I grabbed from a post of mine:

• https://developers.hive.io/ (Official Documentation)
• https://gitlab.syncad.com/hive/hive (Hive source code)
• How to run a witness node on the hf25 testnet
• How To Set Up A Hive Engine Witness- Step By Step Guide
• How to set up a Hive Witness or Seed node (non-MIRA) / Upgrade from Steem-Docker to Hive-Docker
• New Tool For Hive: Witness Voting Page With HiveSigner/Keychain Support
• How To Setup Hive Witness Pricefeed Using Hivefeed-JS

Does running a node weigh down the internet connection much? My family does enjoy our Netflix!

And no, it should consume very little some bandwidth, but nothing that a +20Mbit connection can't deal with (check my other comment). I don't have number right now, but for a witness node is very little. With exception of the initial download of the blockchain which is a little bit more than 500 GB.
