-## Strict mode
-
-In order to have stricter validation (according to http://www.remote.org/jochen/mail/info/chars.html) enable strict mode. You can do this globally by adding the following to your Gemfile:
-
-```ruby
-gem 'email_validator', require: 'email_validator/strict'
-```
-
-Or you can do this in a specific `validates` call:
-
-```ruby
-validates :my_email_attribute, email: {strict_mode: true}
-```

 ## Validation outside a model
 
-If you need to validate an email outside a model, you can get the regexp :

-### Normal mode
+If you'd like to validate an email outside of a model then here are some class methods that you can use:
 
 ```ruby
 EmailValidator.regexp # returns the regex
-EmailValidator.valid?('[email protected]') # boolean
-```
-
-### Strict mode
-
-```ruby
-EmailValidator.regexp(strict_mode: true)
+EmailValidator.valid?('[email protected]') # => true
+EmailValidator.invalid?('[email protected]') # => false
 ```
 
-## Thread safety
+## Validation philosophy
 
-This gem is thread safe, with one caveat: `EmailValidator.default_options` must be configured before use in a multi-threaded environment. If you configure `default_options` in a Rails initializer file, then you're good to go since initializers are run before worker threads are spawned.
+The validation provided by this gem is loose. It just checks that there's an `@` with something before and after it. See [this article by David Gilbertson](https://hackernoon.com/the-100-correct-way-to-validate-email-addresses-7c4818f24643) for an explanation of why.
