+## Build on Linux/macOS
+
+For convenient instead of directly using `crnlib/Makefile` (in which we left it intact for reference and just in case of direct use although not complete solution) to build `crunch` tool, you can execute the following sequence of commands on Linux/macOS to build `crunch` tool as well as static/shared libraries along with header files to be installed on your system.
+
+* `./autogen.sh`
+* `./configure`
+* `make -j4` or `make`
+* `sudo make install`
+
+Thus you can integrate crunch with your own engine/project dynamically, or statically. Note that due to the way autotools behave, we generate the binary tool namely `crunchcli` instead of `crunch` to satisfy the build process (as there is crunch directory inside). So instead of executing `crunch ....` you do `crunchcli ...` instead. But you can rename it freely.
