-# 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:

-
-_Sample output of a Newt container connected to Pangolin and hosting various resource target proxies._
 
 ## 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. 
+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.
-
-### Receives Proxy Control Messages
-
-When Newt receives WireGuard control messages, it will use the information encoded to crate local low level TCP and UDP proxies attached to the virtual tunnel in order to relay traffic to programmed targets.
 
 ## CLI Args
 
-- `endpoint`: The endpoint where both Gerbil and Pangolin reside in order to connect to the websocket.
+-   `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.
+-   `id`: Olm ID generated by Pangolin to identify the olm.
-- `secret`: A unique secret (not shared and kept private) used to authenticate the client ID with the websocket in order to receive commands. 
+-   `secret`: A unique secret (not shared and kept private) used to authenticate the olm ID with the websocket in order to receive commands.
-- `dns`: DNS server to use to resolve the endpoint

+## Environment Variables
+
+All CLI arguments can also be set via environment variables:
+
+-   `PANGOLIN_ENDPOINT`: Equivalent to `--endpoint`
+-   `OLM_ID`: Equivalent to `--id`
+-   `OLM_SECRET`: Equivalent to `--secret`
+-   `MTU`: Equivalent to `--mtu`
+-   `DNS`: Equivalent to `--dns`
+-   `LOG_LEVEL`: Equivalent to `--log-level`
+-   `INTERFACE`: Equivalent to `--interface`
+-   `HTTP_ADDR`: Equivalent to `--http-addr`
+-   `PING_INTERVAL`: Equivalent to `--ping-interval`
+-   `PING_TIMEOUT`: Equivalent to `--ping-timeout`
+-   `HOLEPUNCH`: Set to "true" to enable hole punching (equivalent to `--holepunch`)
+-   `CONFIG_FILE`: Set to the location of a JSON file to load secret values
+
+Examples:
 
 ```bash
-./newt \
+olm \
 --id 31frd0uzbjvp721 \
 --secret h51mmlknrvrwv8s4r1i210azhumt6isgbpyavxodibx1k2d6 \
 --endpoint https://example.com
 ```
 
+You can also run it with Docker compose. For example, a service in your `docker-compose.yml` might look like this using environment vars (recommended):
+
 ```yaml
 services:
-  newt:
+    olm:
-    image: fosrl/newt
+        image: fosrl/olm
-    container_name: newt
+        container_name: olm
-    restart: unless-stopped
+        restart: unless-stopped
-    command:
+        network_mode: host
-        - --id 31frd0uzbjvp721 \
+        devices:
-        - --secret h51mmlknrvrwv8s4r1i210azhumt6isgbpyavxodibx1k2d6 \
+            - /dev/net/tun:/dev/net/tun
-        - --endpoint https://example.com
+        environment:
+            - PANGOLIN_ENDPOINT=https://example.com
+            - OLM_ID=31frd0uzbjvp721
+            - OLM_SECRET=h51mmlknrvrwv8s4r1i210azhumt6isgbpyavxodibx1k2d6
+```
+
+You can also pass the CLI args to the container:
+
+```yaml
+services:
+    olm:
+        image: fosrl/olm
+        container_name: olm
+        restart: unless-stopped
+        network_mode: host
+        devices:
+            - /dev/net/tun:/dev/net/tun
+        command:
+            - --id 31frd0uzbjvp721
+            - --secret h51mmlknrvrwv8s4r1i210azhumt6isgbpyavxodibx1k2d6
+            - --endpoint https://example.com
+```
+
+**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:**
+```json
+{
+  "id": "string",

+      "isRelay": true
+    }
+  }
