 # md5matcher
-Program that will print matches between 2 files (list of hashes and dictionnary).
+
+Simply get matches between 2 files:
+  - A list of hash
+  - A dictionnary
+
+Written in C++ for performance usage.
+
+### Usage
+
+Compile it:
+
+```sh
+git clone https://github.com/biji1/md5matcher.git
+cd md5matcher
+make
+```
+
+Run it:
+
+```sh
+./md5matcher example/hashes example/words
+```
+
+Output:
+
+```sh
+"c0af77cf8294ff93a5cdb2963ca9f038" -> "tree"
+"e6d96502596d7e7887b76646c5f615d9" -> "car"
+"7813258ef8c6b632dde8cc80f6bda62f" -> no match found
