+# DAS2017 ADC RaspberryPi・PYNQ間HTTP通信プログラム
+
+# 概要
+
+DAS2017アルゴリズムデザインコンテストに向けた，端末間通信プラグラム．
+親となるRaspberry Piから，子となる複数のPYNQに対し問題を配信し，結果を受け取る．
+
+# 構成
+
++ server: Raspberry Pi上で実行するためのサーバプラグラム．問題をクライアントに配信し，結果を受け取る．
++ client: PYNQ上で実行するためのクライアントプログラム．問題をサーバから受け取り，問題を解いて回答をサーバに返す．
++ README.md: このファイル．
+
+# Requirements
+
+- Python 3.4以上
+- Flask (pipからインストール)
