Usage:
------

Install BTCPay on this server
This script must be run as root, except on Mac OS

    -i : Run install and start BTCPay Server
    --install-only: Run install only
    --docker-unavailable: Same as --install-only, but will also skip install steps requiring docker
    --no-startup-register: Do not register BTCPayServer to start via systemctl or upstart
    --no-systemd-reload: Do not reload systemd configuration

This script will:

* Install Docker
* Install Docker-Compose
* Setup BTCPay settings
* Make sure it starts at reboot via upstart or systemd
* Add BTCPay utilities in /usr/bin
* Start BTCPay

You can run again this script if you desire to change your configuration.
Except BTC and LTC, other crypto currencies are maintained by their own community. Run at your own risk.

Make sure you own a domain with DNS record pointing to your website.
If you want HTTPS setup automatically with Let's Encrypt, leave REVERSEPROXY_HTTP_PORT at it's default value of 80 and make sure this port is accessible from the internet.
Or, if you want to offload SSL because you have an existing web proxy, change REVERSEPROXY_HTTP_PORT to any port you want. You can then forward the traffic. Just don't forget to pass the X-Forwarded-Proto header.

Environment variables:
    BTCPAY_HOST: The hostname of your website (eg. btcpay.example.com)
    REVERSEPROXY_HTTP_PORT: The port the reverse proxy binds to for public HTTP requests. Default: 80
    REVERSEPROXY_HTTPS_PORT: The port the reverse proxy binds to for public HTTPS requests. Default: 443
    REVERSEPROXY_DEFAULT_HOST: Optional, if using a reverse proxy nginx, specify which website should be presented if the server is accessed by its IP.
    LETSENCRYPT_EMAIL: A mail will be sent to this address if certificate expires and fail to renew automatically (eg. me@example.com)
    NBITCOIN_NETWORK: The type of network to use (eg. mainnet, testnet or regtest. Default: mainnet)
    LIGHTNING_ALIAS: An alias for your lightning network node if used
    BTCPAYGEN_CRYPTO1: First supported crypto currency (eg. btc, ltc, btx, btg, grs, ftc, via, doge, mona, dash, none. Default: btc)
    BTCPAYGEN_CRYPTO2: Second supported crypto currency (Default: empty)
    BTCPAYGEN_CRYPTON: N th supported crypto currency where N is maximum at maximum 9. (Default: none)
    BTCPAYGEN_REVERSEPROXY: Whether to use or not a reverse proxy. NGinx setup HTTPS for you. (eg. nginx, traefik, none. Default: nginx)
    BTCPAYGEN_LIGHTNING: Lightning network implementation to use (eg. clightning, lnd, none)
    BTCPAYGEN_ADDITIONAL_FRAGMENTS: Semi colon separated list of additional fragments you want to use (eg. opt-save-storage)
    ACME_CA_URI: The API endpoint to ask for HTTPS certificate (default: production)
    BTCPAY_ENABLE_SSH: Optional, gives BTCPay Server SSH access to the host by allowing it to edit authorized_keys of the host, it can be used for managing the authorized_keys or updating BTCPay Server directly through the website. (Default: false)
    BTCPAYGEN_DOCKER_IMAGE: Allows you to specify a custom docker image for the generator (Default: btcpayserver/docker-compose-generator)
    BTCPAY_IMAGE: Allows you to specify the btcpayserver docker image to use over the default version. (Default: current stable version of btcpayserver)
    BTCPAY_PROTOCOL: Allows you to specify the external transport protocol of BTCPayServer. (Default: https)
    BTCPAY_ADDITIONAL_HOSTS: Allows you to specify additional domains to your BTCPayServer with https support if enabled. (eg. example2.com,example3.com)
Add-on specific variables:
    LIBREPATRON_HOST: If libre patron is activated with opt-add-librepatron, the hostname of your libre patron website (eg. librepatron.example.com)
    ZAMMAD_HOST: If zammad is activated with opt-add-zammad, the hostname of your zammad website (eg. zammad.example.com)
    WOOCOMMERCE_HOST: If woocommerce is activated with opt-add-woocommerce, the hostname of your woocommerce website (eg. store.example.com)
    BTCPAYGEN_EXCLUDE_FRAGMENTS:  Semicolon-separated list of fragments you want to forcefully exclude (eg. litecoin-clightning)
    BTCTRANSMUTER_HOST: If btc transmuter is activated with opt-add-btctransmuter, the hostname of your btc transmuter website (eg. store.example.com)
    TOR_RELAY_NICKNAME: If tor relay is activated with opt-add-tor-relay, the relay nickname
    TOR_RELAY_EMAIL: If tor relay is activated with opt-add-tor-relay, the email for Tor to contact you regarding your relay
    CHATWOOT_HOST: If chatwoot is activated with opt-add-chatwoot, the hostname of your chatwoot website (eg. store.example.com)
    FIREFLY_HOST: If fireflyiii is activated with opt-add-fireflyiii, the hostname of your libre patron website (eg. firefly.example.com)
