+# Caching Mechanism Usage and Customization
+
+## Overview
+
+The **ApiWrapper** gem includes a flexible caching mechanism to improve performance and reduce redundant API calls. This documentation provides an overview of how to use and customize the caching mechanism.
+
+## Cache Policy
+
+The `CachePolicy` class is responsible for managing caching behavior, including setting global TTLs, custom TTLs for specific endpoints, and controlling which endpoints should bypass the cache.
+
+### Initializing CachePolicy
+
+To use caching, you need to initialize the `CachePolicy` with a cache store and optional global TTL:
+
+```ruby
+require 'api_wrapper/cache/cache_policy'
+require 'api_wrapper/cache/cache_store'
+
+# Initialize the cache store (e.g., in-memory cache store)
+cache_store = ApiWrapper::Cache::CacheStore.new
+
+# Initialize the CachePolicy with the cache store and a global TTL of 300 seconds (5 minutes)
+cache_policy = ApiWrapper::Cache::CachePolicy.new(cache_store, global_ttl: 300)
+```
+
+### Configuring Cache Policy
+#### Adding No-Cache Endpoints
+You can specify endpoints that should bypass the cache:
+```ruby
+# Add an endpoint to the no-cache list
+cache_policy.add_no_cache_endpoint('/no-cache')
+```
+
+#### Adding Custom TTLs
+You can define custom TTLs for specific endpoints:
+
+```ruby
+# Set a custom TTL of 600 seconds (10 minutes) for a specific endpoint
+cache_policy.add_custom_ttl('/custom-ttl', ttl: 600)
+```
+
+#### Fetching Data with Cache
+Use the fetch method to retrieve data with caching applied:
+
+```ruby
+# Fetch data for an endpoint with optional cache
+data = cache_policy.fetch('/some-endpoint') do
+  # The block should fetch fresh data if cache is not used or is stale
+  # e.g., perform an API call or other data retrieval operation
+  Faraday::Response.new(body: 'fresh data')
+end
+```
+## Custom Cache Stores
+You can extend the caching mechanism to support different types of cache stores. Implement a custom cache store by inheriting from the CacheStore base class and overriding the read and write methods.
+
+### Example Custom Cache Store
+```ruby
+class CustomCacheStore < ApiWrapper::Cache::CacheStore
+  def read(key)
+    # Implement custom read logic
+  end
+
+  def write(key, value, ttl)
+    # Implement custom write logic
+  end
+end
+```
+### Using a Custom Cache Store
+To use a custom cache store, initialize CachePolicy with an instance of your custom cache store:
+
+```ruby
+# Initialize the custom cache store
+custom_cache_store = CustomCacheStore.new
+
+# Initialize CachePolicy with the custom cache store
+cache_policy = ApiWrapper::Cache::CachePolicy.new(custom_cache_store, global_ttl: 300)
+```
