# Introduction
This page contains the steps needed to add additional VMProtect 2 virtual instruction profiles to VMProfiler. Understand that these instructions are for version 1.8 and may be different in later versions.

You can also loop through all vm handlers easily. Below is an example of looping through the vm handler vector inside of `vm::ctx_t::vm_handlers`.
```cpp
for ( auto idx = 0u; idx < vmctx.vm_handlers.size(); ++idx )
{
std::printf( "======================== [%s #%d] ========================\n",
vmctx.vm_handlers[ idx ].profile ? vmctx.vm_handlers[ idx ].profile->name : "UNK", idx );
vm::util::print( vmctx.vm_handlers[ idx ].instrs );
// if there is no imm then there are no transforms...
if ( !vmctx.vm_handlers[ idx ].imm_size )
{
std::puts( "\n" );
continue;
}
std::puts( "======================== [transforms] ========================\n" );
for ( auto &[ mnemonic, instr ] : vmctx.vm_handlers[ idx ].transforms )
{
if ( instr.mnemonic == ZYDIS_MNEMONIC_INVALID )
continue;
vm::util::print( instr );
}
std::puts( "\n" );
}
```
***Output***
