+# LNBits
+
+## How to authorize a user
+
+In the node, go to `umbrel/apps/lnbits/docker-compose.yml` and add the user in
+the env variable `LNBITS_ALLOWED_USERS`. This should be a string where each
+user is separated by a comma.
+
+## How to modify config of LNBits
+
+Usually LNBits uses a `.env` file to be configured, but in Umbrel, you need to
+go to the file `umbrel/apps/lnbits/docker-compose.yml` and add whatever env var
+data you want to set up there. These are passed to LNBits on startup.
+
+## Can you transfer sats between the node and an LNBits account?
+
+Yes, one way it's easy and the other way it's a hassle.
+
+If you want to send money from the node to an LNBits account (or talking
+precisely, simply increase the balance of the LNBits account) you can:
+
+1. Create a regular invoice in the LNBits account.
+2. Pay that invoice from the node itself, like in Thunderhub.
+
+Now, if you want to go the other way around (from LNBits to the node) this
+payment won't work. LNBits will complain that the self-payment is not allowed.
+The painful alternative is to edit manually the SQLite database of LNbits to
+make a charge on the LNBits account to lower its balance. The right database is
+in `umbrel/app-data/lnbits/data/database.sqlite3`. This must be done carefully
+to not corrupt it and break up LNBits. Do a backup first in case you fuck
+things up.
+
+## LNDHub
+
+The LNDHub can only be done if the connection goes through HTTPS!!!! Connection
+through HTTP will fail.
+
+---
+
+NOTE: The notes below are from when I tried to run LNBits on a different
+machine than the Umbrel where LND was living. I gave up on that and instead
+simply used the VPS to redirect to the node with Tailscale + NGINX as a reverse
+proxy.
+
+I want to setup an LNBits instance on Navaja that points to Banky. I want to
+run this on Docker.
+
+According to the official docs, this is how you do it:
+
+```shell
+git clone https://github.com/lnbits/lnbits-legend.git
+cd lnbits-legend
+docker build -t lnbits-legend .
+cp .env.example .env
+mkdir data
+docker run --detach --publish 5000:5000 --name lnbits-legend --volume ${PWD}/.env:/app/.env --volume ${PWD}/data/:/app/data lnbits-legend
+```
+
+I see this guide has some interesting bits on how to configure security and
+Nginx
+
+## Changes in the `.env` file
+
+- User control
+    - Add only the desired users to `LNBITS_ALLOWED_USERS`
+    - The users must be uuids in the format that LNBITS follow, no random stuff
+      allowed.
+
+## Connecting to LND
+
+- Macaroon files are located in `umbrel/lnd/data/chain/bitcoin/mainnet`
+- The TLS cert is in `umbrel/lnd/tls.cert`
+- I placed both of those inside the data folder for lnbits and pointed to them
+  from the `.env` file.
+- The default port for the rest api is 8080.
+- I was wondering if things would work with any macaroon with less privileges
+  than the admin one, but I can't find any docs on that.
