+Admin UI
+========
+The LNbits Admin UI lets you change LNbits settings via the LNbits frontend.
+It is disabled by default and the first time you set the enviroment variable LNBITS_ADMIN_UI=true
+the settings are initialized and saved to the database and will be used from there as long the UI is enabled.
+From there on the settings from the database are used.
+
+
+Super User
+==========
+With the Admin UI we introduced the super user, it is created with the initialisation of the Admin UI and will be shown with a success message in the server logs.
+The super user has access to the server and can change settings that may crash the server and make it unresponsive via the frontend and api, like changing funding sources.
+
+Also only the super user can brrrr satoshis to different wallets.
+
+The super user is only stored inside the settings table of the database and after the settings are "reset to defaults" and a restart happened,
+a new super user is created.
+
+The super user is never sent over the api and the frontend only receives a bool if you are super user or not.
+
+We also added a decorator for the API routes to check for super user.
+
+There is also the possibility of posting the super user via webhook to another service when it is created. you can look it up here https://github.com/lnbits/lnbits/blob/main/lnbits/settings.py `class SaaSSettings`
+
+
+Admin Users
+===========
+enviroment variable: LNBITS_ADMIN_USERS, comma-seperated list of user ids
+Admin Users can change settings in the admin ui aswell, with the exception of funding source settings, because they require e server restart and could potentially make the server inaccessable. Also they have access to all the extension defined in LNBITS_ADMIN_EXTENSIONS.
+
+
+Allowed Users
+=============
+enviroment variable: LNBITS_ALLOWED_USERS, comma-seperated list of user ids
+By defining this users, LNbits will no longer be useable by the public, only defined users and admins can then access the LNbits frontend.
+
+
+How to activate
+=============
+```
+$ sudo systemctl stop lnbits.service
+$ cd ~/lnbits-legend
+$ sudo nano .env
+```
+-> set: `LNBITS_ADMIN_UI=true`
+
+Now start LNbits once in the terminal window
+``` 
+$ poetry run lnbits 
+```
+It will now show you the Super User Account:
+
+`SUCCESS | ✔️ Access super user account at: https://127.0.0.1:5000/wallet?usr=5711d7..`
+
+The `/wallet?usr=..` is your super user account. You just have to append it to your normal LNbits web domain.
+
+After that you will find the __`Admin` / `Manage Server`__ between `Wallets` and `Extensions`
+
+Here you can design the interface, it has TOPUP to fill wallets and you can restrict access rights to extensions only for admins or generally deactivated for everyone. You can make users admins or set up Allowed Users if you want to restrict access. And of course the classic settings of the .env file, e.g. to change the funding source wallet or set a charge fee.
+
+Do not forget
+```
+sudo systemctl start lnbits.service
+```
+A little hint, if you set `RESET TO DEFAULTS`, then a new Super User Account will also be created. The old one is then no longer valid.

There's a [guide](https://www.whitewolftech.com/articles/payment-card/) to set it up with a card reader connected to your computer. It can be done (without setting the keys) with [TagWriter app by NXP](https://play.google.com/store/apps/details?id=com.nxp.nfc.tagwriter) Android app. Last but not least, an OSS android app by name [Boltcard NFC Card Creator](https://github.com/boltcard/bolt-nfc-android-app) is being developed for these purposes. It's available from Google Play [here](https://play.google.com/store/apps/details?id=com.lightningnfcapp).
 
 ## About the keys
 
-Up to five 16-byte keys can be stored on the card, numbered from 00 to 04. In the empty state they all should be set to zeros (00000000000000000000000000000000). For this extension only two keys need to be set:

For this extension only two keys need to be set, but for the security reasons all five keys should be changed from default (empty) state. The keys directly needed by this extension are: 
 
-One for encrypting the card UID and the counter (p parameter), let's called it meta key, key #01 or K1.

+The key #00, K0 (also know as auth key) is used as authentification key. It is not directly needed by this extension, but should be filled in order to write the keys in cooperation with Boltcard NFC Card Creator. In this case also K3 is set to same value as K1 and K4 as K2, so all keys are changed from default values. Keep that in your mind in case you ever need to reset the keys manually.
 
 ***Always backup all keys that you're trying to write on the card. Without them you may not be able to change them in the future!***
 
-## Setting the card - bolt-nfc-android-app (easy way)
