-
-The options - and when to choose which - will be explained here shortly:
+![SSH4](pictures/ssh4-blockchain.png)
 
 #### 1. SYNC - Selfvalidate all Blocks
 
-With the new RaspberryPi 4 (with SSD & min 2GB RAM) this is the best way to go. It will take around 2-3 days to sync & validate directly with the bitcoin network. With this option, you have done it the original `don't trust, verify` way.
+With the new RaspberryPi 4 (with SSD & min 2GB RAM) this is the best way to go. It will take around 3-6 days to sync & validate directly with the bitcoin network. With this option, you have done it the original `don't trust, verify` way.
 
 *For the old RaspberryPi 3 this is not recommended. A RaspberryPi 3 has a very low power CPU and syncing+validating the blockchain directly with the peer2peer network can take multiple weeks - that's why for a RP3 you should choose the COPY option .*
 
 #### 2. COPY - Copy from Laptop or another RaspiBlitz over Local Network
 
-First you need to download & validate the blockchain on your own computer/laptop. Todo so install bitcoin-core (0.18.1 or higher) from [bitcoin.org](https://bitcoin.org/en/download) and keep it running until blockchain is synced (will need around 320 GB).
+If you have a friend that is already running a synced RaspiBlitz or you have a laptop with enough free space on the harddrive that can download & validate the Blockchain much faster you can also choose the `COPY` option. You can then delete existing blockchain your RaspiBlitz already started syncing for you. 
 
-Then you can use the COPY option to copy the blockchain over to the RaspiBlitz. This will be done over the local network by SCP (SSH file transfer) - follow the instructions given in the dialogs.
+![SSH4](pictures/ssh4-copy.png)
 
-It's advised to keep a backup of the bitcoin-core & the blockchain data (e.g. on your laptop) in case you need to re-setup the RaspiBlitz.
+To copy from another RaspiBlitz choose `BLITZ` and follow the instructions. Know that the other Blitz will be offline to the lightning network during the copy that will take multiple hours.
+
+To copy from your laptop/computer (`WINDOWNS`, `MACOS` & `LINUX` options) you first need to download & validate the blockchain on your own computer/laptop. Todo so install latest bitcoin-core (0.18.1 or higher) from [bitcoin.org](https://bitcoin.org/en/download) and keep it running until blockchain is synced (will need around 400 GB). Then under the `COPY` option choose the Operating System. The copy will be done over the local network by SCP (SSH file transfer) - follow the instructions given in the dialogs. It's advised to keep a backup of the bitcoin-core & the blockchain data (e.g. on your laptop) in case you need to re-setup the RaspiBlitz.

-You can now decide if you want to setup a fresh new wallet or if you want to recover an old wallet from a RaspiBlitz you had before.
+If you hit OK, the RaspiBlitz will go into a final reboot.
 
-#### Setup a NEW Wallet
+![SSH5](pictures/ssh5-reboot.png)
 
-This is the default if you setup a RaspiBlitz the first time.
+Just wait a bit and then the SSH command to login again. Dont forget to use this time your password A ... which is always for password for system login.
 
-![SSH8](pictures/ssh8-wallet.png)
+![SSH5](pictures/ssh5-unlock.png)
 
-RaspiBlitz will ask you to set your wallet unlock password - use your chosen PASSWORD C here. Confirm by inputting it a second time.
+If you run LND you will be asked to unlock your wallet - thats always your password C. BTW under `SETTINGS` in the main menu you can activate the Auto-Unlock if you prefer.
 
-LND will now generate a fresh cipher seed (word list) for you.

-
-##### SEED+SCB Words Seed & channel.backup file (OK)
-
-Next best option is, if you have the channel.backup file and the word list seed. This is the best chance to recover the on-chain funds you had in open channels. But all channels you had open before will be closed during this procedure.
-
-##### ONLY SEED Only Seed Word List (Fallback)

-### Final LND Setup
-
-It will now make sure your wallet is initialized correctly and may ask you to unlock it with PASSWORD C.
-
-![SSH9c](pictures/ssh9c-unlock.png)
-
-*The LND wallet needs to get unlocked on every new start/reboot of the RaspiBlitz.*
-
-The RaspiBlitz will now do final setup configuration, such as installing tools, moving the SWAP file to the HDD, or activating the firewall. You will see some text moving across the screen until this screen:
-
-![SSH9b](pictures/ssh9b-reboot.png)
-
-The basic setup is done - hooray ... but it may still take some time before everything is ready and you can play around with your new RaspiBlitz. Press 'OK' to reboot. Your terminal session will get disconnected and the raspberry pi restarts.
-
-### First Start: Syncing & Scanning
-
-After the reboot is done, it will take a while for all services to start up - wait until you see on the LCD/display that LND wallet needs to get unlocked. Then SSH in again with the same command like in the beginning (check LCD/display) but this time (and every following login) use your PASSWORD A.
-
-After terminal login, LND will ask you (like on every start/reboot) to unlock the wallet again - use PASSWORD C:
-
-![SSH9c](pictures/ssh9c-unlock.png)
-
-On first start, you will have a longer waiting time (between 10 minutes and 2-3 days, depending on your initial setup) ... but that's OK, just leave the RaspiBlitz running until it's done.
-
-![SSH9d1](pictures/ssh9d-sync.png)
-
-*You can even close your terminal now and shutdown your laptop and ssh back in later on. You will see on the Blitz LCD/display that it is ready when the blue background screen is gone, and you see a status screen.*
-
-To understand what is taking so long .. it's two things:
-
-1. Blockchain Sync
-
-The blockchain on your HDD is not absolutely up-to-date. Depending on how you got it transferred to your RaspiBlitz it will be some hours, days, or even weeks behind. Now the RaspiBlitz needs to catch-up on the rest by directly syncing with the peer-2-peer network until it reaches almost 100%. Even if you see progress at 99.8%, there can still be waiting time - gaining 1% can take up to 4 hours (depending on network speed), so be patient here.
-
-2. Lightning Scanning
-
-Automatically if the Blockchain Sync is progressing LND will start to scan the blockchain and collect information. The Lightning scanning alone normally just takes around 1 hour until the waiting time is over. Can take much longer if you recover on old wallet from seed.
-
-* [Why is my "final sync" taking so long?](FAQ.md#why-is-my-final-sync-taking-so-long)
-
-Once all is done, you should see a status screen on the RaspiBlitz LCD/display like this:
-
-![SSH9dz](pictures/ssh9z-ready.png)
+Remeber that now your RaspiBlitz might need a longer time to sync/validate the blockchain - this can be multiple days. In the beginnig you might see fast progress but its normal that this gets slower later on. Also your RaspberryPi CPU might get quite hot ... thats also OK during this inital sync time - the RaspberryPi has its own protection against overheating and will push thru.
 
 ### Main Menu
 
-If you now login by SSH in your RaspiBlitz (or you are still logged in) you will see the Main Menu:
+Once the Blockchain is synced you will enter the SSH Main Menu:
