# Details

Details is the first step of the personalization flow and the only one you must complete before the experiment exists. Saving this step creates the draft.

## Configuration Details

| Field               | Required | Description                                                |
| ------------------- | -------- | ---------------------------------------------------------- |
| **Experiment Name** | Yes      | A name for the experiment. Names do not have to be unique. |
| **Channel**         | Yes      | The channel the experiment runs on.                        |
| **Language**        | Yes      | The language the experiment runs in.                       |

## Key Considerations

* **Channel** and **Language** decide which pages, components, algorithms, and rules appear later on the **Experience** step. Choose them carefully.
* Once you save this step, both fields become read-only. To change them, clone the experiment and start again.
* If the workspace has only one channel and one language, both fields are hidden and applied automatically.

<Note>
  Personalization has no **Observation** or **Hypothesis** field. Both belong to the A/B test [Details](/experiments/a_b_testing/details) step.
