# Managing knowledge items

> Edit, turn off, schedule, and delete knowledge items, view their change history, and follow best practices

You can manage items from any items table on the Knowledge page. For what an item is, see [Items](/assistant-setup/knowledge#items).

| To... | Do this |
| - | - |
| **Edit** an item | Select its text, make your changes, then select anywhere outside the text box to save. If it's a website item, [lock it](/assistant-setup/website-knowledge#lock-items-to-protect-your-edits) so a re-read doesn't overwrite your edit. |
| **Turn** an item **off or on** | Use the **Active** toggle. Turned-off items are grayed out, and your assistants don't use them. |
| **Schedule** an item | Select the calendar icon. Details are below. |
| **See** an item's **history** | Select the **History** icon. |
| **Delete** an item | Select the trash icon. This can't be undone. |

## Schedule

Select the calendar icon, then set an activation date, an expiration date, or both. Times are Pacific Time.

| You set | What happens |
| - | - |
| **Activation date** | The item stays off until that date, then stays on |
| **Expiration date** | The item is on now and turns off on that date |
| **Both** | The item turns on at the activation date and off at the expiration date |

An item has one schedule at a time.

## Bulk actions

Select the checkbox next to several items, or select **Select all matching** to include every item that matches your filters.

Then choose **Activate**, **Deactivate**, **Schedule**, **Copy**, **Lock from re-read**, **Unlock**, or **Delete**.

**Schedule** replaces any schedule already on the selected items.

**Lock from re-read** and **Unlock** apply to website items. On the By set and All items tabs, they are under **Advanced**.

## Deleting website items

When you delete an item that came from a website, you'll see this warning:

> Assistants stop using it right away. This cannot be undone, and a re-read can add it back while the page still says it. To keep it out for good, turn it off and lock it instead.

## Change history

Each item keeps every change to it: edits, deletes, and items that a re-read turned off.

Each entry shows:

* The date
* The type of change
* The full old and new wording
* Who made the change: you, or a re-read

The wording is shown in full, so you can copy an earlier version back into the item.

## Best practices

* **Put related information in one item.** When you write knowledge, each line becomes its own item, so write one "Gym hours" item instead of one item per day.
* **Start each item with what customers ask about**, such as "Gym hours" or "Membership pricing."
* **Add a focus instruction** when a page mixes the facts you want with material you don't, such as class times and club promos. See [Focus instruction](/assistant-setup/website-knowledge#focus-instruction).
* **Match the schedule to the page.** Weekly for pages that change often, such as class schedules and promotions. Monthly for stable pages.
* **Lock items you've corrected by hand.**
