+# Guide: install Sphinx-relay on myNode.
+
+This guide is focused on installing Sphinx-relay on top of myNode. Information about myNode can be found at: https://mynodebtc.com/.
+
+### Preparations
+
+* Be able to connect with your node through SSH.
+* Make sure you are running LND version `0.9.0` or higher. This can be seen at http://mynode.local/lnd at the right top. Or by inserting the following console command:
+
+```sh
+$ lncli getinfo
+> "version": "0.9.0-beta commit=v0.9.0-beta"
+```
+* Open port `3001/TCP` on your router. How to do this is not included in this guide. https://www.yougetsignal.com/tools/open-ports/ is one of the many websites that can be used to check if a port is opened on your network.
+---
+## Let's Start
+
+### Open port 3001 on myNode
+
+Open up a console window with SSH. And log in as root
+```sh
+$ sudo su
+```
+Open up port 3001 on your machine and make sure it has been added to the list.
+```sh 
+$ ufw allow 3001 comment 'allow Sphinx-Chat'
+$ ufw status
+
+> Status: active
+>
+> To                         Action      From
+> --                         ------      ----
+> 3001 (v6)                  ALLOW       Anywhere (v6)              # Sphinx-Chat
+```
+
+### Download
+
+login as user bitcoin.
+```sh
+$ sudo su bitcoin
+$ cd
+```
+Clone the repository from Github and install the package.
+```sh 
+$ git clone https://github.com/stakwork/sphinx-relay
+$ cd sphinx-relay
+$ npm install
+```
+### Dependencies
+sqlite3: `$ apt-get install sqlite3`
+
+### Configure
+Edit the "production" section of config/app.json.
+```sh 
+$ cd
+$ cd sphinx-relay/config/
+$ nano app.json
+```
+Change the following 4 lines to:
+``` 
+"macaroon_location": "/home/bitcoin/.lnd/data/chain/bitcoin/mainnet/admin.macaroon",
+"tls_location": "/mnt/hdd/mynode/lnd/tls.cert",
+"lnd_log_location": "/home/bitcoin/.lnd/logs/bitcoin/mainnet/lnd.log",
+"lncli_location": "/home/bitcoin/go/bin",
+```
+Save and exit:
+`Ctrl + X`
+
+`Y`
+
+`Enter`
+
+Edit the "production" section of config/config.json
+```sh 
+$ nano config.json
+```
+Change to following line to:
+``` 
+"storage": "/home/bitcoin/sphinx.db"
+```
+Save and exit:
+`Ctrl + X`
+
+`Y`
+
+`Enter`
+
+To connect to your app:
+(replace x.x.x.x with your IP)
+```sh 
+$ cd
+$ cd sphinx-relay/config/
+$ export NODE_IP=x.x.x.x:3001
+```
+For extra security:
+```sh
+$ export USE_PASSWORD=true
+```
+### Activate keysend
+We need LND to run with keysend activated. First we check if it is already activated on your node. To do that. Go to http://mynode.local/lnd/config and check if the line `accept-keysend=1` is included somewhere in the text.
+
+If `accept-keysend=1` is already included you can continue without changing anything. If `accept-keysend=1` is not included, add it to a new line and click the `Save` button. This will restart your device. (Restarting could take up to several minutes but also hours, so be patient.)
+
+### Run
+Now it's time to run the software.
+
+```sh 
+$ cd
+$ cd sphinx-relay/config/
+$ npm run prod
+```
+When Relay starts up, it will print a QR in the terminal. You can scan this in your app (right now Android only) to connect!
