+/**
+ * @defgroup pkg_monocypher Monocypher cryptographic library
+ * @ingroup  pkg
+ * @brief    Provides the Monocypher cryptographic library.
+ *
+ * # Monocypher RIOT package
+ *
+ * Monocypher is a high performance cryptographic library. It provides functions
+ * for authenticated encryption, hashing, password key derivation, key
+ * exchange, and public key signatures.
+ *
+ * You can find the API and more information
+ * [here](https://monocypher.org/manual)
+ *
+ * ## Requirements
+ *
+ * @note    Monocypher only supports 32bit platforms.
+ *
+ * Monocypher requires around 3K of stack space depending slightly on the
+ * platform, so beware that you're allocating at
+ * least `THREAD_STACKSIZE_DEFAULT + 3072` bytes.
+ *
+ * You can do it easily by adding:
+ *
+ * ```makefile
+ * CFLAGS += '-DTHREAD_STACKSIZE_MAIN=(THREAD_STACKSIZE_DEFAULT + 3072)'
+ * ```
+ *
+ * to your makefile.
+ *
+ * ## Usage
+ *
+ * Just add it as a package in your application:
+ *
+ * ```makefile
+ * USEPKG += monocypher
+ * ```
+ *
+ * @see     https://monocypher.org/
