title: Construct Runtime V2 - An outer macro approach to define the runtime

doc:
  - audience: Runtime Dev
    description: |
      Introduces `#[frame_support::runtime]` that can be attached to a mod to define a runtime. The items 
      in this mod can be attached to the following attributes to define the key components of the runtime.
      1. `#[runtime::runtime]` attached to a struct defines the main runtime
      2. `#[runtime::derive]` attached to the runtime struct defines the types generated by the runtime
      3. `#[runtime::pallet_index]` must be attached to a pallet to define its index
      4. `#[runtime::disable_call]` can be optionally attached to a pallet to disable its calls
      5. `#[runtime::disable_unsigned]` can be optionally attached to a pallet to disable unsigned calls
      6. A pallet instance can be defined as `TemplateModule: pallet_template<Instance>`
      An optional attribute can be defined as `#[frame_support::runtime(legacy_ordering)]` to ensure that 
      the order of hooks is same as the order of pallets (and not based on the pallet_index). This is to support 
      legacy runtimes and should be avoided for new ones.
