+# beman.inplace\_vector
+
+A dynamically-resizable vector with fixed capacity and embedded storage
+
+This repository implements `std::inplace_vector` extension targeting C++26.
+The `beman.inplace_vector` library aims to evaluate the stability, 
+the usability, and the performance of these proposed changes before they 
+are officially adopted by WG21 into the C++ Working Draft. 
+Additionally, it allows developers to use these new features before they 
+are implemented in major standard library compilers.
+
+## Implements
+
+- [`inplace_vector` P0843R14](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2024/p0843r14.html)
+
+## Usage
+
+### Definition in P0843
+
+> `inplace_vector` is a dynamically-resizable array with capacity fixed 
+at compile time and contiguous inplace storage, 
+that is, the array elements are stored within the vector object itself. 
+Its API closely resembles `std::vector<T, A>`, 
+making it easy to teach and learn, 
+and the inplace storage guarantee makes it useful in environments in 
+which dynamic memory allocations are undesired.
