-+   home_dir: '..'
--   home_dir: '..',
--   default_index: 'macOS'

-## 2.0.0
-
-### Breaking Changes
-
-- Change the syntax of configuration in the `Rakefile`
-
-### Enchancements
-
-- Add `default_index` option fixes #2
-- Option renaming and simplification by default value
-
-### Migrating from v1.0.x
-
-First, you need to rewrite the `Rakefile` configuration to the v2.0.0 syntax.
-
-```ruby
-# v1.0.x
-Flexdot.install_tasks(
-  target_dir: '/home/username',
-  base_dir: '.'
-)
-```
-
-```ruby
-# v2.0.0
-Flexdot.setup(
-  home_dir: '/home/username',
-  dotfiles_dir: '.'
-)
-```
-
-Note that If the `dotfiles_dir` option is `'.'` (current directory) , you can omit it.
-
-Then, update flexdot to v2.0.0 and you're done.
-
-    $ bundle update flexdot
