+# Technical Principles
+
+Every decision in the Fastify framework and its official plugins is guided by
+the following technical principles:
+
+1. “Zero” overhead in production
+2. “Good” developer experience
+3. Works great for small & big projects alike
+4. Easy to migrate to microservices (or even serverless) and back
+5. Security & data validation
+6. If something could be a plugin, it likely should be
+7. Easily testable
+8. Do not monkeypatch core
+9. Semantic versioning & Long Term Support
+10. Specification adherence
+
+## "Zero" Overhead in Production
+
+Fastify aims to implement features with minimal overhead. This is achieved by
+using fast algorithms, data structures, and JavaScript-specific features.
+
+Since JavaScript does not offer zero-overhead data structures, this principle
+can conflict with providing a great developer experience and additional features,
+as these usually incur some overhead.
+
+## "Good" Developer Experience
+
+Fastify aims to provide the best developer experience at its performance point.
+It offers a great out-of-the-box experience that is flexible enough to adapt to
+various situations.
+
+For example, binary addons are forbidden because most JavaScript developers do
+not have access to a compiler.
+
+## Works great for small and big projects alike
+
+Most applications start small and become more complex over time. Fastify aims to
+grow with this complexity, providing advanced features to structure codebases.
+
+## Easy to migrate to microservices (or even serverless) and back
+
+Route deployment should not matter. The framework should "just work".
+
+## Security and Data Validation
+
+A web framework is the first point of contact with untrusted data and must act
+as the first line of defense for the system.
+
+## If something could be a plugin, it likely should
+
+Recognizing the infinite use cases for an HTTP framework, catering to all in a
+single module would make the codebase unmaintainable. Therefore, hooks and
+options are provided to customize the framework as needed.
+
+## Easily testable
+
+Testing Fastify applications should be a first-class concern.
+
+## Do not monkeypatch core
+
+Monkeypatching Node.js APIs or installing globals that alter the runtime makes
+building modular applications harder and limits Fastify's use cases. Other
+frameworks do this; Fastify does not.
+
+## Semantic Versioning and Long Term Support
+
+A clear [Long Term Support strategy is provided](./LTS.md) to inform developers when
+to upgrade.
+
+## Specification adherence
+
+In doubt, we chose the strict behavior as defined by the relevant
+Specifications.
