 ## Usage
 
 ### Using as a jwks loader when decoding JWT tokens
 
-```
+```ruby
 require "jwt"
 require "jwk-loader"
 
 JWT.decode(token, nil, true, algorithm: "RS512", jwks: JwkLoader.for_uri(uri: "https://url/to/public/jwks") )
 ```
 
+### Testing endpoints protected by JWT tokens
+
+When testing HTTP endpoints protected by asymmetric JWT keys the mechanism in `jwk_loader/test` can be used to simplify the process.
+
+```ruby
+require 'jwk_loader/test'
+
+RSpec.describe 'GET /protected' do
+  include JwkLoader::Test
+
+  context 'when called with a valid token' do
+    let(:token) { sign_test_token(token_payload: { user_id: 'user' }, jwk_endpoint: 'https://url/to/public/jwks') }
+    subject(:response) { get('/protected', { 'HTTP_AUTHORIZATION' => "Bearer #{token}" }) }
+
+    it 'is a success' do
+      expect(response.status).to eq(200)
+    end
+  end
+end
+```
+
 ### Configuring the gem
 
-TODO: Will probably be implemented at some point
+```ruby
+require "jwt-loader"
+
+JwkLoader.configure do |config|
+  config[:cache] = YetAnotherCache.new
+  config[:cache_grace_period] = 999
+end
+```
+
+or in alternative
+
+```ruby
+require "jwt-loader"
+
+JwkLoader.configure do |config|
+  config.cache = YetAnotherCache.new
+  config.cache_grace_period = 999
+end
+```
+
 
 ## Development
 
 After checking out the repo, run `bundle install` to install dependencies. Then, run `bundle exec rspec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
