+it is strongly advised to not use it for production purposes for now. Actually it supports only HTTP. and HTTPS/SSL
 support will be implemented soon. Anyone who wishes to contribute is welcome.
 
 ## Installation
 
 Install the gem and add to the application's Gemfile by executing:

     $ gem install macaw_framework
 
 ## Usage
 
 The usage of the framework still very simple. Actually it support 5 HTTP verbs: GET, POST, PUT, PATCH and DELETE.
-For now, the framework can't resolve client request body and headers. The support for this will be included soon.
 
 The default server port is 8080. To choose a different port, create a file with the name `application.json` 
 in the same directory of the script that will start the application with the following content:
 
 ```json
 {
   "macaw": {
     "port": 8080,
     "bind": "localhost",
-    "threads": 10
+    "threads": 10,
+    "cache": {
+      "cache_invalidation": 3600
+    }
   }
 }
 ```
 
+Cache invalidation time should be specified in seconds. In order to enable caching, The application.json file
+should exist in the app main directory and it need the `cache_invalidation` config set.
+
 Example of usage:
 
 ```ruby
 require 'macaw_framework'
 require 'json'
 
 m = MacawFramework::Macaw.new
 
-m.get('/hello_world') do |context|
+m.get('/hello_world', cache: true) do |context|
   context[:body] # Returns the request body as string
   context[:params] # Returns query parameters and path variables as a hash
   context[:headers] # Returns headers as a hash
   return JSON.pretty_generate({ hello_message: 'Hello World!' }), 200
 end
 
+m.post('/hello_world/:path_variable') do |context|
+  context[:body] # Returns the request body as string
+  context[:params] # Returns query parameters and path variables as a hash
+  context[:headers] # Returns headers as a hash
+  context[:params][:path_variable] # The defined path variable can be found in :params
+  return JSON.pretty_generate({ hello_message: 'Hello World!' }), 200
+end
+
 m.start!
 ```
 
-The above example will start a server and will create a GET endpoint at localhost/hello_world.

-The verb methods must always return a String or nil (Used as response) and a number corresponding the 
-HTTP Status Code to be returned to the client.
+If prometheus is enabled, a get endpoint will be defined at path `/metrics` to collect prometheus metrics. This path
+is configurable via the `application.json` file.

+The verb methods must always return a string or nil (used as the response) and a number corresponding to the HTTP status 
+code to be returned to the client. If an endpoint doesn't return a value or returns nil for both the string and the 
+code, a default 200 OK status will be sent as the response.
