-libndbuf: Network designed buffer ops library
-----------------------------------------------
+libndbuf: Network-oriented buffer operations library
+----------------------------------------------------
 
-1. What the shit is that ?
-This is a quite small library to manipulate with binary packed buffers
-in a normal network manner (i.e. bigendian). It might be useful to
-apply for network packet creating/parsing.
-Anyway, originally this code was resided in my different other *small*
-projects - and i hate copy-paste -- well, that's why it gone to
-this quite small library.
+1. What is it?
+A small C library providing a simple API to read and write typed values
+to/from buffers with correct endianness handling.
 
-2. API
-Check out include directory...
-btw, might be later i will write manpages, but for now didn't see any
-sense for those effort.
-Generally speaking - all is quite simple - create ndbuf_t structure fill
-it in printf() style, read with sscanf() style, take raw data pointer and ...
-send it somewhere whatever bla bla - you get a point.
+2. Purpose
+Make parsing and building network packets easy and concise. The API is
+intended to act like a binary printf/scanf for packet fields.
+
+Example:
+
+Packet layout:
+<16-bit><8-bit><32-bit><raw data>
+
+Reading with a single call:
+ndbuf_escan(buf, "wbdR", &a16, &a8, &a32, &data_ptr)
+
+The same style is used to build packets.
 
 3. Future plans
-Fix bugs (but ... there are no bugs found, since this code was heavly used
-already, but ... report me if found).
-Write manpages (in my few projects those API is like a part of POSIX -
-still cannot remember all).
-Maybe will add a new functions (useful ones).
+ * Improve the API ergonomics (better support for preallocated buffers).
+ * Add convenience helpers and safer bounds checks.
+ * Possibly extend format specifiers and documentation.
