### Introduction
RTL is now enabled to manage lightning nodes running Core Lightning.
Follow the below steps to install and setup RTL to run on Core Lightning.
### Pre-requisites:
1. Functioning Core Lightning node. Follow install instructions on their [github](https://github.com/ElementsProject/lightning)
2. NodeJS - Can be downloaded [here](https://nodejs.org/en/download)
3. Cl-REST - Ensure that `cl-rest` API server is installed and running. Install instructions [here](https://github.com/Ride-The-Lightning/c-lightning-REST)
4. Copy the `access.macaroon` file from `cl-rest` to the device, on which RTL will be installed
### Architecture

### Installation:
To download a specific RTL version follow the instructions on the [release page](https://github.com/Ride-The-Lightning/RTL/releases)
To download from master (*not recommended*):
#### First time setup
```
$ git clone https://github.com/Ride-The-Lightning/RTL.git
$ cd RTL
$ npm install --omit=dev --legacy-peer-deps
```
#### Or: Update existing build
```
$ cd RTL
$ git reset --hard HEAD
$ git clean -f -d
$ git pull
$ npm install --omit=dev --legacy-peer-deps
```
### Prep for Execution
RTL requires its own config file `RTL-Config.json`, to start the server and provide user authentication on the app.
* Rename the file `Sample-RTL-Config.json` to `RTL-Config.json` located at`./RTL`..
* Locate the complete path of the readable `access.macaroon` from `cl-rest` on your node.
* Modify the RTL conf file per the example file below
Ensure that the follow values are correct per your config:
* `lnImplementation` - This should be `CLN`, indicating that RTL is connecting to a core lightning node.
* `macaroonPath` - Path of the folder containing `access.macaroon` file from cl-rest server.
* `lnServerUrl` - complete url with ip address and port of the cl-rest server.
* `multiPass` - Specify the password (in plain text) to access RTL. This password will be hashed and not stored as plain text.
* `configPath` (optional) - File path of the core lightning config file, if RTL server is local to the core lightning server.

### Start the server and access the app
Run the following command:
`$ node rtl`
If the server started successfully, you should get the below output on the console:
`$ Server is up and running, please open the UI at http://localhost:3000 or your proxy configured url.`
Open your browser at the following address: http://localhost:3000 to access the RTL app.
