+# ParamsParser
+
+A Go package for parsing and manipulating parameters from text in a key-value format with support for multiline strings.
+
+## Features
+
+- Parse parameters in a natural format: `key: 'value' anotherKey: 'another value'`
+- Support for multiline string values
+- Support for numeric values without quotes: `port: 25`
+- Support for boolean-like values: `secure: 1`
+- Type conversion helpers (string, int, float, boolean)
+- Default value support
+- Required parameter validation with panic-on-missing options
+- Simple and intuitive API
+
+## Usage
+
+### Basic Usage
+
+```go
+import (
+    "github.com/freeflowuniverse/heroagent/pkg/paramsparser"
+)
+
+// Create a new parser
+parser := paramsparser.New()
+
+// Parse a string with parameters
+inputStr := `
+    name: 'myapp' 
+    host: 'localhost'
+    port: 25
+    secure: 1
+    reset: 1 
+    description: '
+        A multiline description
+        for my application.
+    '
+`
+
+err := parser.Parse(inputStr)
+if err != nil {
+    // Handle error
+}
+
+// Or parse a simpler one-line string
+parser.ParseString("name: 'myapp' version: '1.0' active: 1")
+
+// Set default values
+parser.SetDefault("host", "localhost")
+parser.SetDefault("port", "8080")
+
+// Or set multiple defaults at once
+parser.SetDefaults(map[string]string{
+    "debug": "false",
+    "timeout": "30",
+})
+
+// Get values with type conversion
+name := parser.Get("name")
+port := parser.GetIntDefault("port", 8080)
+secure := parser.GetBool("secure")
+```
+
+### Type Conversion
+
+```go
+// String value (with default if not found)
+value := parser.Get("key")
+
+// Integer value
+intValue, err := parser.GetInt("key")
+// Or with default
+intValue := parser.GetIntDefault("key", 42)
+
+// Float value
+floatValue, err := parser.GetFloat("key")
+// Or with default
+floatValue := parser.GetFloatDefault("key", 3.14)
+
+// Boolean value (true, yes, 1, on are considered true)
+boolValue := parser.GetBool("key")
+// Or with default
+boolValue := parser.GetBoolDefault("key", false)
+```
+
+### Required Parameters
+
+```go
+// These will panic if the parameter is missing or invalid
+value := parser.MustGet("required_param")
+intValue := parser.MustGetInt("required_int_param")
+floatValue := parser.MustGetFloat("required_float_param")
+```
+
+### Getting All Parameters
+
+```go
+// Get all parameters (including defaults)
+allParams := parser.GetAll()
+for key, value := range allParams {
+    fmt.Printf("%s = %s\n", key, value)
+}
+```
+
+## Example Input Format
+
+The parser supports the following format:
+
+```
+name: 'myname' host: 'localhost'
+port: 25
+secure: 1
+reset: 1 
+description: '
+    a description can be multiline
+
+    like this
+'
+```
+
+Key features of the format:
+- Keys are alphanumeric (plus underscore)
+- String values are enclosed in single quotes
+- Numeric values don't need quotes
+- Boolean values can be specified as 1/0
+- Multiline strings start with a single quote and continue until a closing quote is found
+
+## Example
+
+See the [example](./example/main.go) for a complete demonstration of how to use this package.
+
+## Running Tests
+
+```bash
+go test -v ./pkg/paramsparser
