You need permission to add incident timeline events.

Step 1 of 7
Open the event editor
Select Add event on the Timeline tab. Tellagen opens Add timeline event. The dialog contains Title with quick presets under it, Type, Occurred time, Description, Screenshot evidence, Tags, Mark as key event, and Group controls.
Step 2 of 7
Enter the event title
Title is required, and the cursor starts there. Enter a short Title that states what changed, or select a quick preset such as Deploy or Rollback under it.
Step 3 of 7
Set type and time
Select the event Type. Set a valid date and time in Occurred time.
Step 4 of 7
Add optional context
Description is optional. Use it only when the Title needs supporting detail.

Step 5 of 7
Attach screenshots
Under Screenshot evidence, select Choose images. You can also paste an image into the form.
Step 6 of 7
Organize the event
Add useful tags. Select Mark as key event for a key event. Choose a Group when one applies.
Step 7 of 7
Save the event
A nonblank Title enables Add event. Description is optional. Select Add event, or press ⌘/Ctrl+Enter from any field. Tellagen then validates Occurred time and confirms with Event added. An invalid Occurred time can prevent a successful submission after you select Add event.

Timeline shows the event with its title, type, and occurred time. It also shows any optional description, screenshots, tags, star state, or group.

Enter a nonblank Title. Description is optional and does not control the Add event action.

Check Occurred time. Enter a valid date and time, then select Add event again.

Select Choose images again. Use a supported image file without secrets.
