+# Inserter Package
+
+The `inserter` package provides functionality to insert data into a database using Go. It is designed to be flexible and easy to use.
+
+## Installation
+
+To install the `inserter` package, use the following command:
+
+```sh
+go get github.com/jacobbrewer1/patcher/inserter
+```
+
+## Usage
+
+Here is an example of how to use the inserter package:
+
+```go
+package main
+
+import (
+	"fmt"
+
+	"github.com/jacobbrewer1/patcher/inserter"
+)
+
+type User struct {
+	ID    int    `db:"id,pk,autoinc"` // pk = primary key (This field will be ignored by default by the inserter package), autoinc = auto increment
+	Name  string `db:"name"`
+	Email string `db:"email"`
+}
+
+func main() {
+	user := User{
+		Name:  "John Doe",
+		Email: "[email protected]",
+	}
+
+	sql, args, err := inserter.NewBatch([]any{user}, inserter.WithTable("users")).GenerateSQL()
+	if err != nil {
+		panic(err)
+	}
+
+	fmt.Println(sql)
+	fmt.Println(args)
+}
+
+```
+
+This will output the following:
+
+```SQL
+INSERT INTO users (id, name, email) VALUES (?, ?, ?)
+```
+
+with the following arguments:
+
+```
+[1, "John Doe", "[email protected]"]
+```
+
