-# pointer helpers
+# pointerhelpers
 
-Go repo to hold all the helpers for pointers to save rewriting the same code every time
+`pointerhelpers` is a Go package designed to reduce boilerplate code when working with pointers. This package provides helper functions for various data types, including `bool`, `int` (and its variations), `float` (and its variations), `complex` (and its variations), and `string`. By using this package, you can streamline your code and enhance readability.
+
+## Installation
+
+To install the `pointerhelpers` package, use the following command:
+
+```bash
+go get github.com/xorima/pointerhelpers
+```
+
+## Usage
+
+The `pointerhelpers` package provides functions to obtain pointers to values and to safely retrieve values from pointers. Below are the examples for each supported type:
+
+### Boolean
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/xorima/pointerhelpers"
+)
+
+func main() {
+	b := true
+	bPtr := pointerhelpers.Bool(b)
+	fmt.Println(*bPtr) // Output: true
+
+	nilBoolPtr := (*bool)(nil)
+	fmt.Println(pointerhelpers.BoolValue(nilBoolPtr)) // Output: false
+}
+```
+
+### Integers
+
+#### int
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/xorima/pointerhelpers"
+)
+
+func main() {
+	i := 42
+	iPtr := pointerhelpers.Int(i)
+	fmt.Println(*iPtr) // Output: 42
+
+	nilIntPtr := (*int)(nil)
+	fmt.Println(pointerhelpers.IntValue(nilIntPtr)) // Output: 0
+}
+```
+
+#### Other integer types
+
+The package supports other integer types similarly: `int8`, `int16`, `int32`, `int64`, `uint`, `uint8`, `uint16`, `uint32`, `uint64`.
+
+### Floating Point Numbers
+
+#### float32
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/xorima/pointerhelpers"
+)
+
+func main() {
+	f := float32(3.14)
+	fPtr := pointerhelpers.Float32(f)
+	fmt.Println(*fPtr) // Output: 3.14
+
+	nilFloat32Ptr := (*float32)(nil)
+	fmt.Println(pointerhelpers.Float32Value(nilFloat32Ptr)) // Output: 0
+}
+```
+
+#### float64
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/xorima/pointerhelpers"
+)
+
+func main() {
+	f := 3.14
+	fPtr := pointerhelpers.Float64(f)
+	fmt.Println(*fPtr) // Output: 3.14
+
+	nilFloat64Ptr := (*float64)(nil)
+	fmt.Println(pointerhelpers.Float64Value(nilFloat64Ptr)) // Output: 0
+}
+```
+
+### Complex Numbers
+
+#### complex64
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/xorima/pointerhelpers"
+)
+
+func main() {
+	c := complex64(1 + 2i)
+	cPtr := pointerhelpers.Complex64(c)
+	fmt.Println(*cPtr) // Output: (1+2i)
+
+	nilComplex64Ptr := (*complex64)(nil)
+	fmt.Println(pointerhelpers.Complex64Value(nilComplex64Ptr)) // Output: (0+0i)
+}
+```
+
+#### complex128
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/xorima/pointerhelpers"
+)
+
+func main() {
+	c := complex(1 + 2i)
+	cPtr := pointerhelpers.Complex128(c)
+	fmt.Println(*cPtr) // Output: (1+2i)
+
+	nilComplex128Ptr := (*complex128)(nil)
+	fmt.Println(pointerhelpers.Complex128Value(nilComplex128Ptr)) // Output: (0+0i)
+}
+```
+
+#### Embedding Complex64Helper
+
+For users who want to embed `Complex64Helper` into their custom types to gain the pointer helper functionalities directly, the package provides the `Complex64Helper` struct.
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/xorima/pointerhelpers"
+)
+
+type MyStruct struct {
+	pointerhelpers.Complex64Helper
+}
+
+func main() {
+	s := MyStruct{}
+	c := complex64(1 + 2i)
+	cPtr := s.Complex64(c)
+	fmt.Println(*cPtr) // Output: (1+2i)
+
+	nilComplex64Ptr := (*complex64)(nil)
+	fmt.Println(s.Complex64Value(nilComplex64Ptr)) // Output: (0+0i)
+}
+```
+
+### String
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/xorima/pointerhelpers"
+)
+
+func main() {
+	s := "hello"
+	sPtr := pointerhelpers.String(s)
+	fmt.Println(*sPtr) // Output: hello
+
+	nilStringPtr := (*string)(nil)
+	fmt.Println(pointerhelpers.StringValue(nilStringPtr)) // Output: ""
+}
+```
