### <a name="intro"></a>Introduction
RTL is now enabled to manage an Eclair node.

Follow the below steps to install and setup RTL to run on Eclair.

### <a name="prereq"></a>Pre-requisites:
1. Functioning Eclair node v0.4.1 or above. Follow install instructions on their [github](https://github.com/ACINQ/eclair) page.
2. Bitcoin core v0.19.1 or above (this is an Eclair dependency).
3. NodeJS - Can be downloaded [here](https://nodejs.org/en/download)

### <a name="install"></a>Installation:
Eclair is integrated with RTL v0.8.0 and above.
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*) follow the below instructions:
#### 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
```

#### Error on npm install
If there is an error with `upstream dependency conflict` message then replace `npm install --omit=dev` with `npm install --omit=dev --legacy-peer-deps`.

### <a name="prep"></a>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 `eclair.conf` for 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 `ECL`, indicating that RTL is connecting to an Eclair node.
* `lnServerUrl` - complete url with ip address and port of the eclair server.
* `multiPass` - Specify the password (in plain text) to access RTL. This password will be hashed and not stored as plain text.
* `configPath` (Optinal) - Full path of the folder containing `eclair.conf` including the file name. Can be used for the basic password authentication through `eclair.api.password`.
* `lnApiPassword` (Mandatory if configPath is missing) - The same value from eclair.conf's eclair.api.password should be provided directly here. It will be used for Eclair API authentication.

```
### <a name="start"></a>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.
