# Add teaching material

<mark style="color:$primary;">**Outcome**</mark>\
You upload course files, code, or data into the Master Instance, where you will work on them before distributing to students.

<mark style="color:$primary;">**Before you start**</mark>

* You are a Space Administrator of the course (creators automatically receive this role).
* You have the material ready to upload from your local machine.

You always work in the **Master Instance** - a private working environment dedicated to developing and maintaining teaching material. The Master Instance is not visible to students by default. Once material is ready, you distribute it from the Master Instance to all students in one operation.

#### **Upload files via the web UI**

{% stepper %}
{% step %}
Navigate to the course and confirm in the breadcrumbs that you are in the correct Space.
{% endstep %}

{% step %}
Navigate to the Master Instance.
{% endstep %}

{% step %}
Make sure you are in the Current state.
{% endstep %}

{% step %}
On the sidebar, click the folder icon to open the Files view.
{% endstep %}

{% step %}
Click UPLOAD in the top left and select files from your local machine.
{% endstep %}
{% endstepper %}

{% hint style="info" %}
To upload folders, compress them locally first (as .zip or .tar.gz), upload the archive, then extract it from the ... Actions menu in the Files view. Supported formats include zip, tar, tar.gz, bz2, and tgz.
{% endhint %}

For all available file operations (upload, download, extract, preview, edit), see [Reference › File storage](/reference/file-system-and-storage.md).
