 Configuration
 -------------
 
-A JSON file is used to match [user agent strings](http://simplyfast.info/browser) to a list of known bots.
+By default, this gem download [updatable list of known bots](https://github.com/monperrus/crawler-user-agents) and cache it into the `./tmp` directory.
 
-If you'd like to use an [updated list](https://github.com/monperrus/crawler-user-agents) or make your own customizations, run `rake voight_kampff:import_user_agents`. This will download a `crawler-user-agents.json` file into the `./config` directory.
+You can disable file cache with `VoightKampff::Test.cache_path = nil`.
+
+Default TTL of cache is 24 hours. You can change it with `VoightKampff::Test.max_age = number_of_seconds`.
 
 __Note:__ The pattern entries in the JSON file are evaluated as [regular expressions](http://en.wikipedia.org/wiki/Regular_expression).
 
 Usage

 There are three ways to use Voight-Kampff
 
-1. Through Rack::Request such as in your [Ruby on Rails](http://rubyonrails.org) controllers:  
-   `request.bot?`

 Upgrading to version 1.0
 ------------------------
 
-Version 1.0 uses a new source for a list of bot user agent strings since the old source was no longer maintained. This new source, unfortuately, does not include as much detail. Therefore the following methods have been deprecated:

 Also, the gem no longer extends `ActionDispatch::Request` instead it extends `Rack::Request` which `ActionDispatch::Request` inherits from. This allows the same functionality for Rails while opening the gem up to other rack-based projects.
 
+Upgrading to version 2.0
+------------------------
+
+Version 2.0 uses a built-in cache instead of `rake` tasks.
+
+Also, you have to explicitly require `voight_kampff/rack_request` for `Rack::Request` patching.

Once that pull request is merged, feel free to create an issue here and I'll release a new gem version with the updated list. In the meantime you can always run `rake voight_kampff:import_user_agents` on your project to get that updated list.

 __Q:__ __Why don't you use the user agent list from ______________
 If you know of a better source for a list of bot user agent strings, please create an issue and let me know. I'm open to switching to a better source or supporting multiple sources. There are others out there but I like the openness of monperrus' list.
