+# `obistats` Package — Core Statistical Functions
+
+The `obistats` package provides generic, type-safe implementations of fundamental descriptive statistics for numeric types in Go.
+
+## Key Functions
+
+- **`Max[T]()`**  
+  Returns the maximum value in a slice of numeric types (`int`, `int8`–`64`, `float32/64`).  
+  *Implementation*: Iterates once, tracking the largest element.
+
+- **`Min[T]()`**  
+  Returns the minimum value in a slice of numeric types (including unsigned integers: `uint`, `uint8`–`64`).  
+  *Implementation*: Single-pass scan, comparing each element to the current minimum.
+
+- **`Mode[T]()`**  
+  Computes the *most frequent* value (mode) for signed integer types only (`int`, `int8`–`64`).  
+  *Implementation*: Builds a frequency map, then selects the value with highest count.
+
+## Design Notes
+
+- **Generics**: All functions use Go type parameters (`[T ...]`) for compile-time safety and performance.
+- **Type Scope**:
+  - `Max` supports signed integers + floats (no unsigned).
+  - `Min` includes all integer variants.
+  - `Mode` is restricted to signed integers (due to map key constraints and semantics).
+- **Assumptions**: Input slices are non-empty; no explicit error handling for edge cases (e.g., empty input).
+- **Use Case**: Lightweight, reusable utility functions suitable for statistical pipelines or exploratory data analysis.
