 ### How To Compile nDPI

+In order to compile this project do
 
 - ./autogen.sh
-- ./configure
+- make
+
+To compile the library w/o any tools or tests:
+
+- ./autogen.sh --with-only-libndpi
 - make
 
 To run tests do additionally:
 
-- cd tests; ./do.sh
+- ./tests/do.sh # Generate and check for diff's in PCAP files
+- ./tests/do-unit.sh # Run unit tests
+- ./tests/do-dga.sh # Run DGA detection test
+
+or run all with: `make check`
 
-Please note that the pre-requisites for compilation include:
-- GNU tools (autogen, automake, autoconf, libtool)
-- GNU C compiler (gcc)
+Please note that the (minimal) pre-requisites for compilation include:
+- GNU tools (autoconf automake libtool pkg-config gettext flex bison)
+- GNU C compiler (gcc) or Clang

 ### How To Add A New Protocol Dissector
 
 The entire procedure of adding new protocols in detail:
 
-1. Add new protocol together with its unique ID to: src/include/ndpi_protocol_ids.h
-2. Create a new protocol in: src/lib/protocols/
-3. Variables to be kept for the duration of the entire flow (as state variables) need to be placed in: src/include/ndpi_typedefs.h in ndpi_flow_tcp_struct (for TCP only), ndpi_flow_udp_struct (for UDP only), or ndpi_flow_struct (for both).
-4. Add a new entry for the search function for the new protocol in: src/include/ndpi_protocols.h
-5. Choose (do not change anything) a selection bitmask from: src/include/ndpi_define.h
-6. Add a new entry in ndpi_set_protocol_detection_bitmask2 in: src/lib/ndpi_main.c
-7. Set protocol default ports in ndpi_init_protocol_defaults in: src/lib/ndpi_main.c
-8.  ./autogen.sh
-9. make
-10. make check

 ### How to use nDPI to Block Selected Traffic
+
 You can use nDPI to selectively block selected Internet traffic by embedding it onto an application (remember that nDPI is just a library). Both [ntopng](https://github.com/ntop/ntopng) and [nProbe cento](http://www.ntop.org/products/netflow/nprobe-cento/) can do this.
 
 ### nDPI Paper Citation
 
 - Deri, Luca, et al. [nDPI: Open-source high-speed deep packet inspection](http://luca.ntop.org/nDPI.pdf) 2014 International Wireless Communications and Mobile Computing Conference (IWCMC). IEEE, 2014.
 
 ### nDPI-Related Projects

+- [nDPId](https://github.com/utoni/nDPId)
 
 ### DISCLAIMER
+
 While we do our best to detect network protocols, we cannot guarantee that our software is error free and 100% accurate in protocol detection. Please make sure that you respect the privacy of users and you have proper authorization to listen, capture and inspect network traffic.
