===  Download ===
 Inside your home directory, download Cgminer
 git clone https://github.com/Canaan-Creative/cgminer

=== Compile ===
 cd cgminer
 git checkout origin/avalon4 -b avalon4
 ./autogen.sh --enable-avalon4
 make -j 4

=== Run ===
 sudo ./cgminer --avalon4-fan 60 --avalon4-freq 200 --avalon4-voltage 7125 --lowmem -o http://stratum.pool:3333 -u  work -p pass 
 or
