 `BEAR.Resource` connects application data and functionality with resources with [REST constraints](https://en.wikipedia.org/wiki/Representational_state_transfer).
 
-The framework provides constraints and design principles that guide the entire application, promoting consistent design and implementation, resulting in high-quality, clean code.

 ## Libraries
 
 Unlike full-stack frameworks, BEAR.Sunday does not include its own libraries for specific tasks like authentication or database management. Instead, it favors the use of high-quality third-party libraries.
 
-This approach is rooted in two key design philosophies: firstly, the belief that "frameworks remain, libraries change," acknowledging that while the framework provides a stable foundation, libraries evolve to meet changing needs over time. Secondly, it empowers "application architects with the right and responsibility to choose libraries" that best fit their application's requirements, constraints, and goals.

 BEAR.Sunday draws a clear distinction between frameworks and libraries, emphasizing the role of the framework as an application constraint.

 ## Web Cache
 
 The resource-oriented architecture of BEAR.Sunday naturally lends itself to distributed caching, inherent to the Web. By adhering to Web fundamentals, BEAR.Sunday leverages CDN-centric distributed cache systems to achieve the high performance and availability demanded by modern web applications.
 
 - **Distributed Caching**: By caching on the client, CDN, and server-side, both CPU and network costs are minimized.
 
-- **IDENTIFICATION**: ETag-based verification ensures that only modified content is retrieved, enhancing network efficiency.
+- **Identification**: ETag-based verification ensures that only modified content is retrieved, enhancing network efficiency.
 
 - **Fault tolerance**: The adoption of event-driven content enables a system based on permanent CDN caching. Even if PHP or the database goes down, content remains available, enhancing resilience.
 
 ## Performance
 
-BEAR.Sunday strikes a balance between flexibility and performance, with a design focused on efficiency:
+BEAR.Sunday is designed with a focus on performance and efficiency while ensuring maximum flexibility. By compiling the framework's functionality into a root object and resolving dependencies during compilation, it achieves an optimized bootstrap process. This compilation step results in improved startup times and overall execution speed.
 
 - **Injection and Compilation**: By performing dependency injection at compile time, runtime overhead is minimized, resulting in faster application startup and execution.
