 To connect to the lnd node the cert, macaroon and address of the lnd node has to be configured. LnMe uses the LND defaults.
 
-* `address`: Host and port of the lnd gRPC service. default: localhost:10009
-* `cert`: Path to the lnd cert file. default: ~/.lnd/tls.cert
-* `macaroon`: Path to the macaroon file. default: ~/.lnd/data/chain/bitcoin/mainnet/invoice.macaroon
+* `lnd-address`: Host and port of the LND gRPC service. default: localhost:10009
+* `lnd-cert-path`: Path to the LND TLS cert file. default: ~/.lnd/tls.cert
+* `lnd-macaroon-path`: Path to the LND macaroon file. default: ~/.lnd/data/chain/bitcoin/mainnet/invoice.macaroon (invoice.macaroon is recommended)
+
+Instead of the path to the macaroon and cert files you can also provide the hex strings:
+
+* `lnd-cert`: LND TLS cert as HEX string.
+* `lnd-macaroon`: LND macaroon file. (invoice.macaroon is recommended)
 
 #### Other configuration
 
 * `static-path`: Path to a folder that you want to serve with LnMe (e.g. /home/bitcoin/lnme/website). Use this if you want to customize your ⚡website. default: disabled
 * `disable-website`: Disable the default LnMe website. Disable the website if you only want to embed the LnMe widget on your existing website.
 * `disable-cors`: Disable CORS headers. (default: false)
-* `bind`: Host and port to listen on. (default: :1323)
+* `port`: Port to listen on. (default: 1323)
 * `request-limit`: Limit the allowed requests per second. (default: 5)
 
+Depending on your deployment needs LnMe can be configured using the following options:
+
+1. Command line flags
+2. Environment variables
+3. Config TOML file
+
 #### Examples:
 
+##### Command line flags:
+
     $ lnme --help
-    $ lnme --address=lndhost.com:10009 --bind=localhost:4711
+    $ lnme --lnd-address=lndhost.com:10009 --port=4711
     $ lnme --disable-website
 
+##### TOML config file
+
+See [config.toml.example](./toml.config.example) for an example file.
+
+    $ lnme --config=/path/to/config.toml
+
+##### Environment variables
+
+All environment variables must be prefixed by `LNME_` use `_` instead of `-`
+
+    $ LNME_LND_ADDRESS=127.0.0.1:10005 lnme
+
