 Introduction
 ------------
 
-Base64 encoding and decoding easily in C++17 or C99.
+Base64 encoding and decoding easily in C99.
+
+Features
+--------
+
+- base64 encoding,
+- base64 decoding (with base64url support),
+- no dynamic allocation required,
+
+Quick overview
+--------------
+
+Encode data. We use -1 to read until end of input string.
+
+	char encoded[128];
+	size_t size;
+
+	size = b64_encode("Hello world!", -1, encoded, sizeof (encoded));
+
+Decode data. As with previous example, we use -1 to read until enf of base64
+input string.
+
+	char decoded[128];
+	size_t size;
+
+	size = b64_decode("ABx=", -1, decoded, sizeof (decoded));
+
+Note: even with binary data the function `b64_decode` still append a NUL
+terminator. Use the return code from the function to get the size binary data.
