+BitFaster.Caching provides high performance, thread-safe in-memory caching primitives.
+
+# Development Ethos
+
+- This library is performance first, code is carefully optimized at the expense of readability or maintainability.
+- Meta programming based on generics and structs enable the .NET JIT to elide unused code, devirtualize methods and perform other optimizations. Do not change structs into classes unless explicitly asked.
+- API compatibility is important, unless explicitly asked, assume only additive changes can be made to the public API surface.
+
+# Coding Conventions and Style
+
+- We follow the standard [Microsoft C# Coding Conventions](learn.microsoft.com) and use the built-in `dotnet format` tool to enforce style.
+- **Action Hook:** After generating or modifying any code, you must run `dotnet format` to ensure consistency.
