-# stunneld.js
-
-A server that works in combination with [stunnel.js](https://github.com/Daplie/node-tunnel-client)
+A server that works in combination with [Telebit Remote](https://git.coolaj86.com/coolaj86/telebit.js)
 to allow you to serve http and https from any computer, anywhere through a secure tunnel.
 
-CLI
-===
+| Sponsored by [ppl](https://ppl.family) | **Telebit Relay** | [Telebit Remote](https://git.coolaj86.com/coolaj86/telebit.js) |
 
-Installs as `stunnel.js` with the alias `jstunnel`
-(for those that regularly use `stunnel` but still like commandline completion).
+Features
+========
 
-### Install
+* [x] Expose your bits even in the harshest of network environments
+  * [x] NAT, Home Routers
+  * [x] College Dorms, HOAs
+  * [x] Corporate Firewalls, Public libraries, Airports
+  * [x] and even Airplanes, yep
+* [x] Automated HTTPS (Free SSL)
+
+Install
+=======
+
+Mac & Linux
+-----------
+
+Open Terminal and run this install script:
 
 ```bash
-npm install -g stunneld
+curl -fsSL https://get.telebit.cloud/relay | bash
 ```
 
-### Advanced Usage
+Of course, feel free to inspect the install script before you run it.
 
-How to use `stunnel.js` with your own instance of `stunneld.js`:
+This will install Telebit Relay to `/opt/telebit-relay` and
+put a symlink to `/opt/telebit-relay/bin/telebit-relay` in `/usr/local/bin/telebit-relay`
+for convenience.
+
+You can customize the installation:
 
 ```bash
-stunneld.js --servernames tunnel.example.com --protocols wss --secret abc123
+export NODEJS_VER=v10.2
+export TELEBIT_RELAY_PATH=/opt/telebit-relay
+curl -fsSL https://get.telebit.cloud/relay
+```
+
+That will change the bundled version of node.js is bundled with Telebit Relay
+and the path to which Telebit Relay installs.
+
+You can get rid of the tos + email and server domain name prompts by providing them right away:
+
+```bash
+curl -fsSL https://get.telebit.cloud/relay | bash -- jon@example.com telebit-relay.example.com
+```
+
+Windows & Node.js
+-----------------
+
+1. Install [node.js](https://nodejs.org)
+2. Open _Node.js_
+2. Run the command `npm install -g telebit-relay`
+
+**Note**: Use node.js v8.x or v10.x
+
+There is [a bug](https://github.com/nodejs/node/issues/20241) in node v9.x that causes telebit-relay to crash.
+
+Manually Install
+-----------
+
+```bash
+git clone https://git.coolaj86.com/coolaj86/telebit-relay.js.git telebit-relay
+
+# we're very picky to due to bugs in various versions of v8, v9, and v10
+export NODEJS_VER="v10.2.1"
+
+# We can keep everything self-contained
+export NPM_CONFIG_PREFIX=/opt/telebit-relay
+export NODE_PATH=/opt/telebit-relay/lib/node_modules
+
+curl -fsSL https://bit.ly/node-installer | bash -s -- --no-dev-deps
+
+pushd /opt/telebit-relay
+  bin/node bin/npm install
+  rsync -a examples/telebit-relay.yml etc/telebit-relay.yml
+  rsync -a dist/etc/systemd/system/telebit-relay.service /etc/systemd/system/telebit-relay.service
+popd
+
+# IMPORTANT: Season the config file to taste
+# IMPORTANT: change your email address and domain
+edit /opt/telebit-relay/etc/telebit-relay.yml
+
+adduser --home /opt/telebit-relay --gecos '' --disabled-password telebit >/dev/null 2>&1
+sudo chown -R telebit:telebit /opt/telebit-relay/
+
+systemctl daemon-reload
+systemctl restart telebit-relay
+
+systemctl status telebit-relay
+journalctl -xefu telebit-relay
+```
+
+Usage
+====
+
+```bash
+telebit-relay --config /opt/telebit-relay/etc/telebit-relay.yml
 ```
 
 Options
 
+`/opt/telebit-relay/etc/telebit-relay.yml:`
 ```
---secret          the same secret used by stunnel client (used for authentication)

-                  incoming http and https should be forwarded

-### Privileged Ports without sudo
+Security
+========
+
+The bottom line: As with everything in life, there is no such thing as anonymity
+or absolute security. Only use Telebit Relays that you trust or self-host. :D
+
+Even though the traffic is encrypted end-to-end, you can't just trust any Telebit Relay
+willy-nilly.
+
+A man-in-the-middle attack is possible using Let's Encrypt since an evil Telebit Relay
+would be able to complete the http-01 challenges without a problem
+(since that's where your DNS is pointed when you use the service).
+
+Also, the traffic could still be copied and stored for decryption is some era when quantum
+computers exist (probably never).
+
+Why?
+====
+
+We created this for anyone to use on their own server or VPS,
+but those generally cost $5 - $20 / month and so it's probably
+cheaper to purchase data transfer, which is only $1/month for
+most people.
+
+In keeping with our no lock-in policy, we release a version of
+the server for anyone to use independently.
+
+TODO show how to do on
+
+	* Node WS Tunnel (zero setup)
+	* Heroku (zero cost)
+	* Chunk Host (best deal per TB/month)
+
+Useful Tidbits
+===
+
+## As a systemd service
+
+`./dist/etc/systemd/system/telebit-relay.service` should be copied to `/etc/systemd/system/telebit-relay.service`.
+
+The user and group `telebit` should be created.
+
+## Use privileged ports without sudo
 
 ```bash
 # Linux
 sudo setcap 'cap_net_bind_service=+ep' $(which node)
 ```
 
-### Alterntive Methods
+API
+===
 
-**NOT YET IMPLEMENTED**
+The authentication method is abstract so that it can easily be implemented for various users and use cases.
 
-We created this for anyone to use on their own server or VPS,
-but those generally cost $5 - $20 / month and so it's probably
-cheaper to purchase data transfer (which we supply, obviously),
-which is only $1/month for most people.
+```
+// bin/telebit-relay.js
+state.authenticate()                  // calls either state.extensions.authenticate or state.defaults.authenticate
+                                      // which, in turn, calls Server.onAuth()
 
-Just use the client ([stunnel.js](https://github.com/Daplie/node-tunnel-client))
-with Daplie's tunneling service (the default) and save yourself the monthly fee
-by only paying for the data you need.
+state.extensions = require('../lib/extensions');
+state.extensions.authenticate({
+  state: state                        // lib/relay.js in-memory state
+, auth: 'xyz.abc.123'                 // arbitrary token, typically a JWT (default handler)
+})
