 Both work with your Bitcoin node to provide a richer set of information to wallets than could be done with bitcoind alone.  They are basically identical in purpose, their differences are notably in the software memory requirements and how snappily they can answer the same questions.
 Electrum (and some other wallets) require more than just a Bitcoin node to run in a sovereign way, they require an “Electrum Server”. Both Electrum Personal Server and Bitcoin Wallet Tracker are “Electrum servers”.
 
+I want to use my hardware signer, such as Coldcard or Trezor with my Embassy.  How does this work?
+--------------------------------------------------------------------------------------------------
+You do not use hardware signers directly with your node. Hardware signers interface with wallets, and wallets interface with nodes.
+
+Node (Embassy) <— Wallet (Specter, Sparrow, Electrum) <— Hardware signer (Coldcard, Trezor)
+
+You would use your hardware with your wallet, then instruct that wallet to use Embassy as its node.
+
+- Nodes are for interacting with the Bitcoin network: enforcing consensus rules, validating and relaying blocks/transactions, and broadcasting transactions.
+
+- Wallets are for constructing and viewing transactions, as well as generating addresses.
+
+- Signers are for generating and storing keys, as well as signing transactions.
+
+The reason there is so much confusion about these 3 concepts is that the Bitcoin Core Node comes with its own Wallet (which you should not use), and that wallet is also a signer. In fact, most wallets double as signers, and most wallets do NOT support connecting to your own node. So, most wallets are actually serving as a wallet, a node, and a signer, which might be convenient, but it is neither trustless nor maximally secure. Ideally, you are using a wallet that supports both integrating with a hardware signer (like Coldcard or Trezor) AND a backend node (like on the Embassy).
+
+Please note: of the wallets listed (Specter/Sparrow/Electrum), only Specter is currently able to use Embassy as it's node, but the other two should be available soon.

 Which wallets can I use that sync with my Embassy Bitcoin node?
 ---------------------------------------------------------------
 There are many wallets that support linking to your own full node.  You will need one that supports tor.  Here are a few options that are compatible: FullyNoded, Samourai, Specter, Wasabi, Zap, and Zeus.

 ----------------------------------------
 Currently, the Embassy itself is designed to for a single user. There is no way to grant others access to your Embassy without sharing your personal, master password, which is not recommended. There are certain services, however, such as Bitwarden, File Browser, and Mastodon, that absolutely support multiple users (aka multi-tenancy, aka uncle Jim model) where people who trust you can create their own, personal accounts for these services on your Embassy. Just remind them that they are trusting you with their data, and that it might be preferable for them to take the final leap of self-sovereignty and get an Embassy of their own.
 
+What can I do if I am having issues connecting to an Android app?
+-----------------------------------------------------------------
+Unfortunately, Orbot can be finicky, and therefore the best solution to Android issues is normally to restart Orbot, or to reboot the phone.  This will solve most common problems.

 Do I need to delete existing backups before doing a new backup? Or does a new backup override the old backup?
 -------------------------------------------------------------------------------------------------------------
 No, you don’t need to delete the old backups. The technology we use updates the existing backup.
