Basic *nix build instructions:

./    # Only needed if building from git repo.
./    # Only needed if building on Mac OS X or with Clang.
./configure CFLAGS="-O3" # For ARM-based devices, please, use
                         # CFLAGS="-O3 -funroll-loops -fomit-frame-pointer"
                         # Alternatively, check out the _arm_ branch of this
                         # repository, and build the project from there.

Notes for AIX users:

* To build a 64-bit binary, export OBJECT_MODE=64
* GNU-style long options are not supported, but are accessible
  via configuration file

Architecture-specific notes:

ARM:	No runtime CPU detection. The miner can take advantage
	of some instructions specific to ARMv5E and later processors,
	but the decision whether to use them is made at compile time,
	based on compiler-defined macros.

	To use NEON instructions, add "-mfpu=neon" to CFLAGS.

x86:	The miner checks for SSE2 instructions support at runtime,
	and uses them if they are available.

x86-64:	(Note: SSE works better than AVX and AVX2 for Yescrypt)
	The miner can take advantage of AVX, AVX2 and XOP instructions,
	but only if both the CPU and the operating system support them.

	    * Linux supports AVX starting from kernel version 2.6.30.
	    * FreeBSD supports AVX starting with 9.1-RELEASE.
	    * Mac OS X added AVX support in the 10.6.8 update.
	    * Windows supports AVX starting from Windows 7 SP1 and
	      Windows Server 2008 R2 SP1.

	The configure script outputs a warning if the assembler
	doesn't support some instruction sets. In that case, the miner
	can still be built, but unavailable optimizations are left off.

Usage instructions: Run minerd --help to see options.

To Connect to pool using your Koto Wallet Address:

    ./minerd -o stratum+tcp://Koto.pool.address:port -u Your_Koto_Address -p x

Note: Do not mine to online wallet addresses, including exchanges, as you may experience loss of coins due to how newly mined coins are confirmed.

Connecting through a proxy: Use the --proxy option.

To use a SOCKS proxy, add a socks4:// or socks5:// prefix to the proxy host.

Protocols socks4a and socks5h, allowing remote name resolving, are also available since libcurl 7.18.0.

If no protocol is specified, the proxy is assumed to be a HTTP proxy.

When the --proxy option is not used, the program honors the http_proxy and all_proxy environment variables.

Also many issues and FAQs are covered in these forum threads dedicated to this program:
