-# Newt
+# Olm
 
-Newt is a fully user space [WireGuard](https://www.wireguard.com/) tunnel client and TCP/UDP proxy, designed to securely expose private resources controlled by Pangolin. By using Newt, you don't need to manage complex WireGuard tunnels and NATing.
+Olm is a [WireGuard](https://www.wireguard.com/) tunnel client designed to securely connect your computer to Newt sites running on remote networks.
 
 ### Installation and Documentation
 
-Newt is used with Pangolin and Gerbil as part of the larger system. See documentation below:
+Olm is used with Pangolin and Newt as part of the larger system. See documentation below:

-<img src="public/screenshots/preview.png" alt="Preview"/>
-
-_Sample output of a Newt container connected to Pangolin and hosting various resource target proxies._
+-   [Full Documentation](https://docs.pangolin.net)
 
 ## Key Functions
 
 ### Registers with Pangolin
 
-Using the Newt ID and a secret, the client will make HTTP requests to Pangolin to receive a session token. Using that token, it will connect to a websocket and maintain that connection. Control messages will be sent over the websocket.
+Using the Olm ID and a secret, the olm will make HTTP requests to Pangolin to receive a session token. Using that token, it will connect to a websocket and maintain that connection. Control messages will be sent over the websocket.
 
 ### Receives WireGuard Control Messages
 
-When Newt receives WireGuard control messages, it will use the information encoded (endpoint, public key) to bring up a WireGuard tunnel using [netstack](https://github.com/WireGuard/wireguard-go/blob/master/tun/netstack/examples/http_server.go) fully in user space. It will ping over the tunnel to ensure the peer on the Gerbil side is brought up. 
-
-### Receives Proxy Control Messages
-
-When Newt receives WireGuard control messages, it will use the information encoded to create a local low level TCP and UDP proxies attached to the virtual tunnel in order to relay traffic to programmed targets.
+When Olm receives WireGuard control messages, it will use the information encoded (endpoint, public key) to bring up a WireGuard tunnel on your computer to a remote Newt. It will ping over the tunnel to ensure the peer is brought up.

-- `endpoint`: The endpoint where both Gerbil and Pangolin reside in order to connect to the websocket.
-- `id`: Newt ID generated by Pangolin to identify the client.
-- `secret`: A unique secret (not shared and kept private) used to authenticate the client ID with the websocket in order to receive commands. 
-- `dns`: DNS server to use to resolve the endpoint
-- `log-level` (optional): The log level to use. Default: INFO
+-   `endpoint`: The endpoint where both Gerbil and Pangolin reside in order to connect to the websocket.
+-   `id`: Olm ID generated by Pangolin to identify the olm.
+-   `secret`: A unique secret (not shared and kept private) used to authenticate the olm ID with the websocket in order to receive commands.
+-   `mtu` (optional): MTU for the internal WG interface. Default: 1280
+-   `dns` (optional): DNS server to use to resolve the endpoint. Default: 8.8.8.8
+-   `log-level` (optional): The log level to use (DEBUG, INFO, WARN, ERROR, FATAL). Default: INFO

+
+**Docker Configuration Notes:**
+
+- `network_mode: host` brings the olm network interface to the host system, allowing the WireGuard tunnel to function properly
+- `devices: - /dev/net/tun:/dev/net/tun` is required to give the container access to the TUN device for creating WireGuard interfaces
+
+## Loading secrets from files
+
+You can use `CONFIG_FILE` to define a location of a config file to store the credentials between runs. 
+
+```
+$ cat ~/.config/olm-client/config.json
+{
+  "id": "spmzu8rbpzj1qq6",
+  "secret": "f6v61mjutwme2kkydbw3fjo227zl60a2tsf5psw9r25hgae3",
+  "endpoint": "https://app.pangolin.net",
+  "tlsClientCert": ""
+}
+```
+
+This file is also written to when newt first starts up. So you do not need to run every time with --id and secret if you have run it once! 
+
+Default locations: 
+
+- **macOS**: `~/Library/Application Support/olm-client/config.json`
+- **Windows**: `%PROGRAMDATA%\olm\olm-client\config.json`
+- **Linux/Others**: `~/.config/olm-client/config.json`
+
+## Hole Punching
+
+In the default mode, olm "relays" traffic through Gerbil in the cloud to get down to newt. This is a little more reliable. Support for NAT hole punching is also EXPERIMENTAL right now using the `--holepunch` flag. This will attempt to orchestrate a NAT hole punch between the two sites so that traffic flows directly. This will save data costs and speed. If it fails it should fall back to relaying.
+
+Right now, basic NAT hole punching is supported. We plan to add:
+
+-   [ ] Birthday paradox
+-   [ ] UPnP
+-   [ ] LAN detection
+
+## Windows Service
+
+On Windows, olm has to be installed and run as a Windows service. When running it with the cli args live above it will attempt to install and run the service to function like a cli tool. You can also run the following:
+
+### Service Management Commands
+
+```
+# Install the service
+olm.exe install
+
+# Start the service
+olm.exe start
+
+# Stop the service
+olm.exe stop
+
+# Check service status
+olm.exe status
+
+# Remove the service
+olm.exe remove
+
+# Run in debug mode (console output) with our without id & secret
+olm.exe debug
+
+# Show help
+olm.exe help
+```
+
+Note running the service requires credentials in `%PROGRAMDATA%\olm\olm-client\config.json`.
+
+### Service Configuration
+
+When running as a service, Olm will read configuration from environment variables or you can modify the service to include command-line arguments:
+
+1. Install the service: `olm.exe install`
+2. Set the credentials in `%PROGRAMDATA%\olm\olm-client\config.json`. Hint: if you run olm once with --id and --secret this file will be populated! 
+3. Start the service: `olm.exe start`
+
+### Service Logs
+
+When running as a service, logs are written to:
+
+-   Windows Event Log (Application log, source: "OlmWireguardService")
+-   Log files in: `%PROGRAMDATA%\olm\logs\olm.log`
+
+You can view the Windows Event Log using Event Viewer or PowerShell:
+
+```powershell
+Get-EventLog -LogName Application -Source "OlmWireguardService" -Newest 10
+```
+
+## HTTP Endpoints
+
+Olm can be controlled with an embedded http server when using `--enable-http`. This allows you to start it as a daemon and trigger it with the following endpoints:
+
+### POST /connect
+Initiates a new connection request.
+
+**Request Body:**

+```bash
+curl -X POST http://localhost:8080/connect \
