-# Libcache [](https://travis-ci.org/silk8192/libcache) [](https://badge.fury.io/rb/libcache)
-
-A caching library that provides in-memory and file based cache
-
-## Installation
-
-Add this line to your application's Gemfile:
-
-```ruby
-gem 'libcache'
-```
-
-And then execute:
-
- $ bundle
-
-Or install it yourself as:
-
- $ gem install libcache
-
-## Usage
-
-For an in memory Cache with an expiry time of 3 seconds, store location at 'foo\bar', a max size of 500, and refresh method where 100 is added to the key (of course more sophisticated value retrieving operations will replace this method). Of course these additions are optional and configurable. The simplest form of an in-memory cache is ```CacheBuilder.with(Cache).build```
-```ruby
-
-cache = CacheBuilder.with(Cache).set_expiry('3s').set_max(500).set_refresh(Proc.new { |key| key + 100 }).build
-
-cache.put(1, 5)
-cache.get(1) # will return 5
-sleep 4 # note that this is more than the expiry time
-cache.get(1) # will return 105 as the data has been refreshed
-cache.exists?(1) # will return true. if there is no set_refresh method provided then it will return false
-
-# delete all data on exit of program
-at_exit do
- cache.invalidateAll
-end
-
-```
-
-For an file-based Cache with an expiry time of 3 seconds, store location at 'foo\bar', and refresh method where 100 is added to the key (of course more sophisticated value retrieving operations will replace this method). Of course these additions are optional and configurable. The only thing that is non-removable is the ```set_store``` method.
-```ruby
-cache = CacheBuilder.with(FileCache).set_store('foo\bar').set_expiry('3s').set_expiry('3s').set_max(500).set_refresh(Proc.new { |key| key + 100 }).build
-
-cache.put(1, 5)
-cache.get(1) # will return 5
-sleep 4 # note that this is more than the expiry time
-cache.get(1) # will return 105 as the data has been refreshed
-cache.exists?(1) # will return true. if there is no set_refresh method provided then it will return false
-
-
-# delete all leftover files on exit of program
-at_exit do
- cache.invalidateAll
-end
-```

-
-## Development
-
-After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
-
-To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).

+# Libcache [](https://travis-ci.org/silk8192/libcache) [](https://badge.fury.io/rb/libcache)
+
+A simple caching library that provides flexible and powerful caching features such as in-memory and file based caching similar to Guava's Caching system.
+
+## Features
+
+* Supports in-memory cache
+* Supports filesystem based cache
+* Limiting the size of the cache through eviction based on a specified max size
+* Allows for expiration behavior based on the time since an object was placed in the cache or when it was last accessed/updated
+* Allows custom refresh functions for reloading expensive data once it has been discarded
+
+
