 ## Usage
 
-``` go
+### SpinnerManager
+
+A `SpinnerManager` is a collection of spinners that share a common configuration.
+
+They can be created as follows:
+
+```go
+sm := ysmrr.NewSpinnerManager()
+```
+
+The `NewSpinnerManager` method also accepts multiple options. For example, you can change the animation and the color of the spinner:
+
+```go
+sm := ysmrr.NewSpinnerManager(
+    ysmrr.WithAnimation(animations.Pipe),
+    ysmrr.WithSpinnerColor(colors.FgHiBlue),
+)
+```
+
+A `SpinnerManager` is also responsible for starting and stopping a group of spinners.
+
+#### Starting a spinner group
+
+```go
+sm.Start()
+```
+
+#### Stopping a spinner group
+
+```go
+sm.Stop()
+```
+
+### Spinners
+
+`SpinnerManagers` are great but pretty useless on their own. You need to add at least one spinner.
+
+Adding a new spinner is as simple as using the `AddSpinner` method on a `SpinnerManager` instance.
+
+It expects a string that will be displayed as the initial message of a spinner.
+
+```go
+spinner := sm.AddSpinner("Downloading...")
+```
+
+`AddSpinner` will return a spinner instance that you can use to control the spinner.
+
+#### Updating the message
+
+Thoughout the lifecycle of a spinner, you can update the message of the spinner.
+
+```go
+spinner.UpdateMessage("Downloading...")
+```
+
+#### Spinner state
+
+A spinner can be set to either `Complete` or `Error` to indicate the current state of a task.
+
+```go
+spinner.Complete()
+```
+
+```go
+spinner.Error()
+```
+
+### Example
+
+To tie everything together, here is an example that shows how to build a
+basic spinner app.
+
+```go
 // Create a new spinner manager
 sm := ysmrr.NewSpinnerManager()
