+# Passing Arguments To A Rake Task
+
+You can create a rake task that takes arguments by including an array of
+named arguments in the task declaration.
+
+```ruby
+task :greeting, [:name] do |task, args|
+  puts "Hello, #{args.name}!"
+end
+```
+
+You can then pass an argument to that task when invoking it.
+
+```bash
+$ rake greeting[World]
+Hello, World!
+```
