After creating a Teacher Story / Evidence you can add artifacts by clicking Upload Files which allows you to select files from your computer to include as evidence such as pictures or various documents you may have written.
Simply click Add Files to select the files you want to include. Then click Start upload to upload them to our server. Once the files are uploaded, click Finish to close the window and return to your story.
After Finishing you should see the files you uploaded.
If an artifact was mistakenly uploaded you can remove it from the story by clicking the orange Trash Bin icon beside it.
