 Bails uses [pruning](https://bitcoin.org/en/release/v0.12.0#wallet-pruning) when the USB stick is less than 1 TB. All block chain data will be downloaded and verified but the oldest blocks will be removed so your USB stick does not run out of space. Unless you wish to restore an old wallet, this doesn't matter.

 Bails will work well on most USB sticks if your computer has at least 8 GB of memory. Tails will start and Bitcoin Core will sync and shutdown much faster if the drive has high "IOPS". This performance is not commonly advertised on the package so here are some models that are top performers, using one of these will reduce your startup and initial sync time by 50-90%:

 1 TB of storage is needed to not prune the block chain. This allows your node to fully support the network serving all historical blocks, but it doesn't personally help you unless you have a 10 year old wallet to restore.
-Picking a USB stick 8 to 16+ times larger than your computer's RAM maximizes performance but isn't necessary. 8 GB laptops are known to sync on budget 64 GB USB sticks in under 4 days if that helps you choose. While 4 GB Laptops are able to sync in 4 days on SSD-like USB sticks. Once you are synced, every USB stick and computer will perform well.

 ## I don't have a computer, what type should I get?
 
 In addition to [Tails' recommendations](https://tails.net/doc/about/requirements/index.en.html), here are some Bails specific tips for selecting a computer to buy, buy and return, rent or borrow to complete the initial sync as fast as possible:
 
-1. **Avoid computers with 4 GB of RAM or less**, they will force your USB stick to work much harder, wearing it out prematurely. On 4GB RAM, without one of the "SSD-like" drives above, the initial synchronization could take weeks instead of days. 8GB RAM is better and 16GB RAM is best. With 16GB RAM computers *most* USB sticks will complete initial sync in hours, rather than days on 8GB RAM computers.
+1. **New computers may be better if paranoid.** There are more opportunities in the supply chain to compromise a used, renewed, open-box or refurbished computer. But these options are reasonably safe if the seller does not know you intend to use the computer for Bitcoin. Paying with cash is another step to prevent linking your identity to the computer.
 
-2. **Storage drive type and capacity don't matter.** Tails never uses your computer's storage. You're free to use this computer for other purposes or return it, after removing your Bails USB stick. Bails would even work with a used PC from eBay that has no internal disk!

 # During Setup
 
 ## What’s the deal with the "Do you trust this individual?"
 
-In short if you know who they are and believe they could have reviewed the bitcoin source code and built it then you can trust their signature. If you don't trust anyone on the list, ask someone trustworthy who they would trust. Or go back and click "Skip" and I’ll pick 2 randomly from a list of who I think are good.
+In short, if you know who they are, know their GPG fingerprint belongs to them and believe they could have reviewed the Bitcoin Core source code and built it, then you can trust their signature. If you don't trust anyone on the list, ask someone trustworthy who they would trust. Or go back and click "Skip" to let the Bails developers choose whose signatures to trust.
 
 ## Does it matter what order I enter shares when restoring?
-No. But right now, you do have to keep your laptop on until you’ve reached a threshold. So if you’d have to fetch some of those by travel or video calls it makes sense to enter those first so you’re not waiting around with as many shares stored in the computers memory. For this reason the seed backup passphrase is always last.

 ## How reliable is my USB stick?
-For reliability, it SHOULD be a new USB stick, not a heavily used one, and it SHOULD be kept cool in use and in storage. And having more RAM on the PC and capacity on the USB stick, ideally 16+ GB RAM and 16x more USB stick capacity than RAM helps reduce wear. As well as shutting down the node less often. Further, some "Industrial" SD cards have better temperature and data loss resistance in storage than fast/large consumer USB sticks, these could be better for infrequently updated backups.

 # After Setup
 
 ## If I wanted to unplug Bails and use the computer for another task will the core download just restart where it left off on the next time I log in?
-If you shutdown Bitcoin Core safely, waiting for it to exit before shutting down Tails (from the menu in the upper right) it will resume where you left off the next time you Start on Tails, unlock its Persistent Storage, and connect to Tor.
-If you shutdown Tails without exiting Bitcoin core safely, or by yanking the USB stick out, it is possible to corrupt the blockchain database and lose your progress. Only remove the USB to shutdown Tails in an Emergency.
