<Steps>
  <Step title="Set Name of Material Blend">
    ```json theme={null}
    "name": "string",
    ```
  </Step>

  <Step title="Specify the Lifecycle Stage">
    For each lifecycle stage, specify the lifecycle. Use the lifecycle code, as referenced below:

    * P002 = Yarn Formation
    * P003 = Textile Formation
    * P004 = Preparation
    * P005 = Dyeing
    * P006 = Finishing

    ```json theme={null}
    "cycleProcess": [
        {
          "lifeCycle": "P002",
          ...
        },
        {
          "lifeCycle": "P003",
          ...
        },
        {
          "lifeCycle": "P004",
          ...
        },
        {
          "lifeCycle": "P005",
          ...
        },
        {
          "lifeCycle": "P006",
          ...
        }
      ]
    ```
  </Step>

  <Step title="Set Country for Lifecycle Stage">
    Lifecycle stages can be adjusted with primary FEM data, or country energy grid data. Indicate one or the other.
    When both are defined, PIC will assign priority to the FEM data and fall back on the country field if the FEM data does not apply to the lifecycle stage for the base material.

    ```json theme={null}
    {
        "lifeCycle": "P002",
        "country": "BD"
    },
    ```
  </Step>

  <Step title="Set the Supplier Worldly ID">
    ### facilityWorldlyId

    Field type: string

    ```json theme={null}
    "facilityWorldlyId": "string"
    ```
  </Step>

  <Step title="Specify the Material Constituents">
    ### baseMaterials

    For each base Material specify:

    **field: materialId**
    Use the *Base Materials List* endpoint to identify the materialId for each material.

    Example: MatTX0001

    **field: composition**: Note that the sum of all composition must equal exactly 100.

    ```json theme={null}
    "baseMaterials": [
        {
          "id": "TX0010",
          "composition": 100
        }
      ]
    ```
  </Step>
