 Successful compilation is the first step. The recommended procedure is to folllow thw Linux build instructions for installing dependencies.
 
 `$ ./autogen.sh`
 
-`$ CFLAGS="-O2 -march=armv8-a+crypto+sha2+aes -Wall -flax-vector-conversions" ./configure  --with-curl`
+`$ CFLAGS="-O2 -march=native -Wall -flax-vector-conversions" ./configure  --with-curl`
 
 `$ make -j $nproc`
  
-"native" can be substituted for -march=.
-It's recommended testing with different builds with and without aes or sha2 or both to test different code for algos that support those features.
