+long-description = """# SPARK Constant Time Big Integer library
+
+Implementation of a constant time big integer library, inspired by [crypto-bigint](https://github.com/RustCrypto/crypto-bigint).
+
+All functions are implemented in constant time, except those with an explicit `_Vartime` suffix. Overloaded operators are also constant time.
+
+> \u26A0\uFE0F The constant time choice primitives like `Ct_Eq`, `Ct_Gt`, `Cond_Select` and `CSwap` rely on best-effort optimisation barriers.
+
+## Usage
+
+The implementations are generic over the size of the integer:
+
+```ada
+package U256 is new Bigints.Uint (256);
+package U1024 is new Bigints.Uint (1024);
+```
+
+There is also a generic package to deal with modular integers (over a prime field):
+
+```ada
+P : U256.Uint := ... --  a big prime, like 2**255 - 19
+package GF_P is new Bigints.Modular (U256, P);
+```
+
+It is up to the user of the library to ensure the chosen modulus is effectively prime. Otherwise, operations like field inversion become invalid (as it relies on Fermat's little theorem).
+
+## Formal proof
+
+The preinstantations in the library (packages `U256s` and `F25519`), as well as the constant time primitives and basic limb primitives, are formally checked using GNATprove.
