# Which version of the Myndr extension do the students have?

|| We regularly publish a new version of the Myndr extension. Sometimes to add new features, sometimes to fix bugs. So it's a good idea to make sure the students' laptops are up to date!
To find out which version of the Myndr extension your students have, do the following on the student's laptop:

### 1 - Type in the browser's address bar: [`test.myndr.net`](https://test.myndr.net)

You'll now land on the page that shows all known information about the Myndr extension.

### 2 - Check whether the extension is installed

In large letters, it says whether or not the extension is installed.

### 3 - You'll find the version number after the extension's ID

Next to the extension, you'll first see the ID, then an icon for the browser the extension was made for, then the version.
The version consists of a major version, for example `v2`, and a detailed version, for example `2.1.16`.
If several extensions have accidentally been installed, you'll see that here too.

### 4 - Check that all connections are OK

Further down the page, a number of connections are checked. If something related to the extension's functionality can't be reached properly from the laptop, it's shown here.
