+[![uint256_t](https://github.com/calccrypto/uint256_t/actions/workflows/uint256_t.yml/badge.svg)](https://github.com/calccrypto/uint256_t/actions/workflows/uint256_t.yml)
+
+## Acknowledgements
+With much help from Auston Sterling
+
+Thanks to Stefan Deigmüller for finding
+a bug in operator*.
+
+Thanks to François Dessenne for convincing me
+to do a general rewrite of this class.
+
+Thanks to John Skaller for making symbols visible
+when compiling as a shared library.
+
+## Usage
+This is simple implementation of an unsigned 256 bit
+integer type in C++. It's meant to be used like a standard
+`uintX_t`, except with a larger bit size than those provided
+by C/C++.
+
+`uint256_t` requires [`uint128_t`](https://github.com/calccrypto/uint128_t), which is included.
+
+### In Code
+All that needs to be done in code is `#include "uint256_t.h"`
+
+```c++
+#include <iostream>
+#include "uint256_t.h"
+
+int main() {
+    uint256_t a = 1;
+    uint256_t b = 2;
+    std::cout << (a | b) << std::endl;
+    return 0;
+}
+```
+
+### Compilation
+A C++ compiler supporting at least C++11 is required.
+
+Compilation can be done by directly including `uint128_t.cpp` and `uint256_t.cpp` in your compile command, e.g. `g++ -std=c++11 main.cpp uint128_t.cpp uint256_t.cpp`, or other ways, such as linking the `uint128_t.o` and `uint256_t.o` files, or creating a library, and linking the library in.
