+# Migration Guide: `gocron` v1 → v2
+
+This guide helps you migrate your code from the `v1` branch to the `v2` branch of [go-co-op/gocron](https://github.com/go-co-op/gocron).
+Version 2 is a major rewrite focusing on improving the internals of gocron, while also enhancing the user interfaces and error handling.
+All major functionality has been ported over.

+## Overview of Major Changes
+
+- **Breaking API changes**: All major interfaces and types have changed.
+- **Improved error reporting**: Most functions now return errors.
+- **Job IDs and cancellation**: Jobs have unique IDs and can be cancelled.
+- **Distributed and monitored scheduling**: Built-in support for distributed schedulers and job monitors.
+- **Context and logging enhancements**: Improved support for cancellation, context, and custom logging interfaces.
+

+
+## Installation
+
+Update your dependency to v2:
+
+```sh
+go get github.com/go-co-op/gocron/v2
+```
+
+**Note:** The import path is `github.com/go-co-op/gocron/v2`.
+
+---
+
+## API Changes
+
+### 1. Scheduler Creation
+
+**v1:**
+```go
+import "github.com/go-co-op/gocron"
+
+s := gocron.NewScheduler(time.UTC)
+```
+
+**v2:**
+```go
+import "github.com/go-co-op/gocron/v2"
+
+s, err := gocron.NewScheduler()
+if err != nil { panic(err) }
+```
+- **v2** returns an error on creation.
+- **v2** does not require a location/timezone argument. Use `WithLocation()` if needed.
+
+---
+
+### 2. Job Creation
+
+**v1:**
+```go
+s.Every(1).Second().Do(taskFunc)
+```
+
+**v2:**
+```go
+j, err := s.NewJob(
+    gocron.DurationJob(1*time.Second),
+    gocron.NewTask(taskFunc),
+)
+if err != nil { panic(err) }
+```
+- **v2** uses explicit job types (`DurationJob`, `CronJob`, etc).
+- **v2** jobs have unique IDs: `j.ID()`.
+- **v2** returns an error on job creation.
+
+#### Cron Expressions
+
+**v1:**
+```go
+s.Cron("*/5 * * * *").Do(taskFunc)
+```
+
+**v2:**
+```go
+j, err := s.NewJob(
+    gocron.CronJob("*/5 * * * *"),
+    gocron.NewTask(taskFunc),
+)
+```
+
+#### Arguments
+
+**v1:**
+```go
+s.Every(1).Second().Do(taskFunc, arg1, arg2)
+```
+
+**v2:**
+```go
+j, err := s.NewJob(
+    gocron.DurationJob(1*time.Second),
+    gocron.NewTask(taskFunc, arg1, arg2),
+)
+```
+
+---
+
+### 3. Starting and Stopping the Scheduler
+
+**v1:**
+```go
+s.StartAsync()
+s.Stop()
+```
+
+**v2:**
+```go
+s.Start()
+s.Shutdown()
+```
+
+- Always call `Shutdown()` for graceful cleanup.
+
+---
+
+### 4. Error Handling
+
+- Most v2 methods return errors. Always check `err`.
+- Use `errors.go` for error definitions.
