 ==== ARM fadd vs vadd
 
-It is very confusing, but `fadds` and `faddd` in Aarch32 are <<gnu-gas-assembler-arm-unified-syntax,pre-UAL>> for `vadd.f32` and `vadd.f64`.
+It is very confusing, but `fadds` and `faddd` in Aarch32 are <<gnu-gas-assembler-arm-unified-syntax,pre-UAL>> for `vadd.f32` and `vadd.f64` which we use in this tutorial: <<arm-vadd-instruction>>
 
 The same goes for most ARMv7 mnemonics: `f*` is old, and `v*` is the newer better syntax.
 
-But then, in ARMv8, they decided to use `fadd` as the main floating point add name, and get rid of `vadd`!

 Also keep in mind that fused multiply add is `fmadd`.
