When you're done, your lessons have their videos, worksheets, PDFs, audio and links where students need
them.

**Who can do this:** the account owner and editors, on the Academy plan.

## Upload files first

A lesson can only use files you've uploaded to its course.

1. Open the course and click the **Files** tab.
2. Click **Upload files** and pick one or more files.

![The course's Files tab: a note on what files lessons can use, the Upload files button, and Baking kit checklist.pdf, used in 1 lesson and in the published version.](https://mjmtbasmrtksluvlnema.supabase.co/storage/v1/object/public/help-media/web-optimized/academy-educators/videos-files-links/SS-ACAD-027-01__files-tab__academy__detail__v01.webp?v=cf0ce06b6e)

- Lessons can offer PDF, Word, Excel, PowerPoint, OpenDocument, text, Markdown, CSV, RTF, EPUB and ZIP
  files, images (PNG, JPG, WebP, GIF) and audio (MP3, M4A, WAV, OGG, AAC). Video files can't be
  uploaded: see below.
- Each file can be up to 50 MB, and course files count toward your account's 10 GB of storage. A course
  can hold up to 200 files.
- Only students with a place on the course can open the files, through links that expire.
- The list shows how many lessons use each file, and whether the published version uses it. To delete
  a file, take it out of every lesson first. If the published version still uses it, publish the course
  without it before you delete it.

## Show a PDF or offer a download

1. In the lesson, click **File or PDF**.
2. Choose the uploaded file (1). Give it a **Title (optional)** if you like.
3. For a PDF, turn on **Show the PDF in the lesson** (2) to show it in the page; students can still
   download it. Other files, images included, are offered as a download.
4. Click **Save lesson**.

![A File or PDF block with Baking kit checklist.pdf chosen and the switch to show the PDF in the lesson turned on, then a Link block to a web page with a title and a note.](https://mjmtbasmrtksluvlnema.supabase.co/storage/v1/object/public/help-media/web-optimized/academy-educators/videos-files-links/SS-ACAD-027-02__file-and-link__academy__desktop__v01.webp?v=229b1e4c29)

## Add a video

Chirp Builder doesn't store video files. Upload your video to YouTube, Vimeo, Loom, Wistia, Bunny
Stream, Cloudflare Stream or Mux, then:

1. In the lesson, click **Video**.
2. Paste the video's link into **Video link**: for YouTube, Vimeo, Loom and Wistia, the link from the
   Share button; for Bunny Stream, Cloudflare Stream and Mux, the embed or player link. Add a
   **Caption (optional)** if you like.
3. Click **Save lesson**.

![A Video block with a YouTube link pasted in, a caption, and the list of video hosts it accepts under the box.](https://mjmtbasmrtksluvlnema.supabase.co/storage/v1/object/public/help-media/web-optimized/academy-educators/videos-files-links/SS-ACAD-027-03__video-block__academy__desktop__v01.webp?v=2ae7075cab)

The video plays inside the lesson. Anyone who has the video host's own link can still watch it there,
so use your video host's privacy settings if that matters to you.

## Add audio

Click **Audio**, then choose:

- **Uploaded file:** an audio file from the **Files** tab.
- **Link:** an https link to an MP3 (or M4A, WAV, OGG or AAC) file, or a SoundCloud or Spotify episode
  link.

## Add a link

Click **Link** and fill in the web address, a **Title** and, if you like, a **Note (optional)**. Students
see that the link opens outside the course.

New blocks reach students when you [publish the course](https://www.chirpbuilder.com/help/academy-educators/publish) again.
