include pattern in output

-v flag now prints the cli version

new flag -e prints extra console info

new flag -f, prevents the CLI from splitting strings on spaces. This allows users to pass string requests containing spaces (setting devices, naming channel labels etc)

 # Voicemeeter Remote Command Line Utility
 
-## `Tested against`
+[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](LICENSE)
+[![Platform](https://img.shields.io/badge/platform-Windows-blue)](#requirements)
 
-- Basic 1.1.1.1
+> A command-line interface for controlling Voicemeeter
-- Banana 2.1.1.1
-- Potato 3.1.1.1
 
-## `Requirements`
+## Compatibility
 
-- [Voicemeeter](https://voicemeeter.com/)
+| Voicemeeter Version | Status |
+|-------------------|--------|
+| Basic 1.1.2.2 | ✅ Tested |
+| Banana 2.1.2.2 | ✅ Tested |
+| Potato 3.1.2.2 | ✅ Tested |
 
-## `Use`
+## Requirements
+
+- **[Voicemeeter](https://voicemeeter.com/)** - Any version (Basic, Banana, or Potato)
+- **Windows** operating system
+- **Command line environment** (PowerShell, CMD, or Terminal)
+
+## Usage
 
 ```powershell
-.\vmrcli.exe [-h] [-i|-I] [-k] [-D] [-v] [-c] [-m] [-s] <api commands>
+.\vmrcli.exe [OPTIONS] <api_commands>
 ```
 
-Where:
+### Command Line Options
 
-- `h`: Prints the help message.
+| Option | Description | Example |
-- `i`: Enable interactive mode, use (-I) to disable the '>>' prompt.
+|--------|-------------|----------|
-  - If set, any api commands passed on the command line will be ignored.
+| `-h` | Print help message | `vmrcli.exe -h` |
-- `k`: The kind of Voicemeeter (basic, banana or potato). Use this to launch the GUI.
+| `-v` | Show version information | `vmrcli.exe -v` |
-- `D`: Set log level 0=TRACE, 1=DEBUG, 2=INFO, 3=WARN, 4=ERROR, 5=FATAL
+| `-i` | Enable interactive mode | `vmrcli.exe -i` |
-- `v`: Enable extra console output (toggle, set messages)
+| `-I` | Interactive mode without prompt | `vmrcli.exe -I` |
-- `c`: Load a user configuration (give the full file path)
+| `-f` | Don't split input on spaces | `vmrcli.exe -f` |
-- `m`: Launch the MacroButtons application
+| `-k <type>` | Launch Voicemeeter GUI | `-kbasic`, `-kbanana`, `-kpotato` |
-- `s`: Launch the StreamerView application
+| `-l <level>` | Set log level | `-lDEBUG`, `-lINFO`, `-lWARN` |
+| `-e` | Enable extra console output | `vmrcli.exe -e` |
+| `-c <path>` | Load user configuration | `-c "C:\config.txt"` |
+| `-m` | Launch MacroButtons app | `vmrcli.exe -m` |
+| `-s` | Launch StreamerView app | `vmrcli.exe -s` |
+
+> **Note:** When using interactive mode (`-i`), command line API commands are ignored.
 
 ## `API Commands`
 
-- Commands starting with `!` will be toggled, use it with boolean parameters.
+### Command Types
-- Commands containing `=` will set a value. (use `+=` and `-=` to increment/decrement)
-- All other commands with get a value.
 
-Examples:
+| Syntax | Action | Example |
+|--------|---------|---------|
+| `!command` | **Toggle** boolean values | `!strip[0].mute` |
+| `command=value` | **Set** a parameter | `strip[0].gain=2.5` |
+| `command+=value` | **Increment** a parameter | `bus[0].gain+=1.2` |
+| `command-=value` | **Decrement** a parameter | `bus[0].gain-=3.8` |
+| `command` | **Get** current value | `strip[0].label` |
 
-Launch basic GUI, set log level to INFO, Toggle Strip 0 Mute, print its new value, then decrease Bus 0 Gain by 3.8
+> **Tip:** Use quotes around values containing spaces: `'strip[0].label="my device"'`
+
+---
+
+### Examples
+
+#### **Basic Operations**
+*Toggle mute, get values, and adjust gain*
 
 ```powershell
-.\vmrcli.exe -kbasic -D2 !strip[0].mute strip[0].mute bus[0].gain-=3.8
+.\vmrcli.exe -kbasic -lINFO !strip[0].mute strip[0].mute bus[0].gain-=3.8
 ```
 
-Launch banana GUI, set log level to DEBUG, set Strip 0 label to podmic then print Strip 2 label
+#### **Setting Labels with Spaces**
+*Set labels and print them back*
 
 ```powershell
-.\vmrcli.exe -kbanana -D1 strip[0].label=podmic strip[2].label
+.\vmrcli.exe -kbanana -lDEBUG 'strip[0].label="my podmic"' strip[0].label
 ```
 
-#### `Quick Commands`
+#### **Device Configuration**
+*Configure hardware devices with complex names*
 
-A short list of quick commands are available:
+```powershell
+.\vmrcli.exe -lDEBUG bus[2].mute=1 bus[2].mute 'bus[2].device.wdm="Realtek Digital Output (Realtek(R) Audio)"'
+```
 
-- `lock`: command.lock=1
+#### **Batch Operations**
-- `unlock`: command.lock=0
+*Multiple strip configurations in one command*
-- `show`: command.show=1
-- `hide`: command.show=0
-- `restart`: command.restart=1
 
-They may be used in direct or interactive mode.
+```powershell
+.\vmrcli.exe `
+  'strip[0].label="my podmic"' strip[0].label !strip[0].mute `
+  'strip[1].label="my wavemic"' strip[1].label !strip[1].mute
+```
 
-## `Interactive Mode`
+### Quick Commands
 
-Running the following command in Powershell:
+*Convenient shortcuts for common Voicemeeter operations*
 
+| Command | API Equivalent | Description |
+|---------|----------------|-------------|
+| `lock` | `command.lock=1` | 🔒 Lock Voicemeeter parameters |
+| `unlock` | `command.lock=0` | 🔓 Unlock Voicemeeter parameters |
+| `show` | `command.show=1` | 👁️ Show Voicemeeter interface |
+| `hide` | `command.show=0` | 🙈 Hide Voicemeeter interface |
+| `restart` | `command.restart=1` | 🔄 Restart Voicemeeter engine |
+
+> **Available in both direct and interactive modes**
+
+## Interactive Mode
+
+*Real-time command interface for live audio control*
+
+**Start interactive session:**
 ```powershell
 .\vmrcli.exe -i
 ```
 
-Will open an interactive prompt:
+**Interactive prompt:**
-
 ```powershell
 Interactive mode enabled. Enter 'Q' to exit.
 >>
 ```
 
-API commands follow the same rules as listed above. Entering `Q` or `q` will exit the program.
+> **Important:** Command line API arguments are ignored when using `-i`
 
-## `Script files`
+## Script Files
 
-Scripts can be loaded from text files, for example in Powershell:
+*Automate complex audio setups with script files*
 
+### Loading Scripts
+
+**From file content:**
 ```powershell
-.\vmrcli.exe -D1 $(Get-Content .\example_commands.txt)
+.\vmrcli.exe -lDEBUG $(Get-Content .\example_commands.txt)
 ```
 
-You may also pipe a scripts contents to the CLI:
+**Via pipeline:**
-
 ```powershell
-$(Get-Content .\example_commands.txt) | .\vmrcli.exe -D1 -I
+$(Get-Content .\example_commands.txt) | .\vmrcli.exe -lDEBUG -I
 ```
 
-Multiple API commands can be in a single line, they may be separated by space, `;` or `,`.
+### Script Format Rules
 
-Lines starting with `#` will be interpreted as comments.
+| Feature | Syntax | Example |
+|---------|--------|----------|
+| **Multiple commands per line** | Space, `;`, or `,` separated | `strip[0].mute=1;bus[0].gain+=2` |
+| **Comments** | Lines starting with `#` | `# This is a comment` |
 
-## `Build`
+## Build Instructions
 
-Run the included `makefile` with [GNU Make](https://www.gnu.org/software/make/).
+*Compile from source using GNU Make*
 
-The binary in [Releases][releases] is compiled with coloured logging enabled. To disable this you can override the `LOG_USE_COLOR` variable, for example:
+### Prerequisites
+- [GNU Make](https://www.gnu.org/software/make/) 
+- GCC compiler (recommended)
+- Windows development environment
 
-`make LOG_USE_COLOR=no`
+### Build Commands
 
-## `Official Documentation`
+```bash
+# Standard build
+make
 
-- [Voicemeeter Remote C API][remoteapi-docs]
+# Disable colored logging
+make LOG_USE_COLOR=no
 
-## `Special Thanks`
+# Clean build artifacts
+make clean
+```
 
-- [rxi][rxi-user] for writing the [log.c][log-c] package
+> **Pre-built binaries** are available in [Releases][releases] with coloured logging enabled
