### How to edit lnd.conf?

To customize LND settings which are not available as environment variables, you can [create a custom fragment](../Docker/README.md#how-can-i-customize-the-generated-docker-compose-file) in `docker-compose-generator/docker-fragments/opt-lnd-config.custom.yml` like this:

### How to edit .lightning/config?

To customize the [Core Lightning settings](https://docs.corelightning.org/reference/lightningd-config) which are not available as environment variables, you can [create a custom fragment](../Docker/README.md#how-can-i-customize-the-generated-docker-compose-file) in `docker-compose-generator/docker-fragments/opt-lightningd-config.custom.yml` like this:

```yml
version: '3'
services:
clightning_bitcoin:
environment:
LIGHTNINGD_OPT: |
alias=MyNodeName
rgb=003366
```

You can add your customizations in the `LIGHTNINGD_OPT` value, like shown by setting the `alias` and `rgb` values.

Afterwards the configuration has to be added to the additional fragments and setup needs to be run:

```bash
export BTCPAYGEN_ADDITIONAL_FRAGMENTS="$BTCPAYGEN_ADDITIONAL_FRAGMENTS;opt-lightningd-config.custom"
. ./btcpay-setup.sh -i
```

This way your custom settings gets added to the config and they will persist updates.

## Lightning Network Questions and Support

Community support for Lightning Network questions is pretty limited, since the protocol is fairly new.
