+/**
+ * @defgroup pkg_nanocbor NanoCBOR library
+ * @ingroup  pkg
+ * @ingroup  sys
+ * @brief    CBOR encoder and decoder library for tiny devices
+ *
+ * This package contains the NanoCBOR library for a small CBOR encoder and
+ * decoder. Flash footprint for encoding and decoding should be below 1K each.
+ *
+ * At the moment 8 bit and 16 bit MCU support is broken by upstream, see the
+ * [issue](https://github.com/bergzand/NanoCBOR/issues/18).
+ *
+ * ## Usage
+ *
+ * Just add it as a package in your application:
+ *
+ * ```makefile
+ * USEPKG += nanocbor
+ * ```
+ *
+ * @see      https://github.com/bergzand/nanocbor
