=== Linux(Beta) ===The To run OSCAR on a Chromebook, it must have a feature added to recent ChromeBooks is called '''Linux(Beta). You may ''', also find this feature described by the codeword known as '''Crostini'''. If you your ChromeBook supports Linux(Beta), then you can run OSCAR on it. If it doesn't, then you can't.

Most CPAP machines use a full size SD Card thoughI think I went too far with separate pages in the Oscar Help system.-->

<!-- There are an awful of of words here. It's very very hard to follow as written. I strongly suggest re-writing this section with some images. --> ===What type of CPU do I have?===Oscar has several versions, and you need to select the correct version to work with the CPU in your Chromebook. If you have enabled Linux(Beta), then the next stage in the installation process is to learn which kind of CPU your ChromeBook uses.To do this: *Open the browser, and type chrome://version and press enter*You will see a list of headings in Bold type foolowed by a colon, on the left hand side of the page.*To the right of that there will be lots of information about Chrome and Chrome OS*Look for the left side heading '''User Agent:''' * to the right of that there will be a line in normal font that looks like *Mozilla/5.0 (X11; CrOS aarch64 12871.67.0) or *Mozilla/5.0 (X11; CrOS x86_64 12871.67.0)*We are interested in whether your ChromeBook says aarch64 or x86_64 on that first line after CrOS*If you see x86_64, then you will need the Oscar package with '''amd64''' in its name (see next section), or*If you see aarch64, then you will need the Oscar package with '''arm64''' in its name. === Does my ChromeBook have an SD Card slot? ===It almost certainly does, but it might be a slot for a micro SD Card. Most CPAP machines use a full size SD Card though. If your ChromeBook has a micro SD Card slot, then you can still use it, but you must either* Use a micro SD Card to full size SD Card adapter (many micro SD Cards are sold with one.* Use your full size SD Card with a USB adapter which will fit in a USB port in your ChromeBook. (Some ChromeBooks may have only USB-C ports, so check this before buying an adapter).

It will see text that tells make a screenshot,(which you what type might want to do to post a display of CPU you your CPAP results) but it may be all black, or haveblue diagonal lines on a white background.  We expect the Chrome OS developers will fix this will likely be AMD, or Intelbut in the meantime, use the Chrome OS way of taking a screenshot. It still works just fine, eitheras a full screen or you may see aarch64 or ARMv8partial selectable one.If you see Intel or AMDRemember that ChromeBooks do not have function keys by default, then you and so all Oscar shortcuts using functions keys will need the package be inaccessible with amd64 in its name, or if you see aarch64 or ARMv8, then you will need the package with arm64 in its namefunction key. However they can all be invokes by another method.

Go to the [https://www.sleepfiles.com/OSCAR/ Oscar downloads page; there's ] <!-- Just use the link, not a link to description that close is subject to the middle of the black horizontal barconfusion -->not far from the top of this page.Go to that page on your Chromebook, and over on the right side, you'll see the 2 two ChromeBook installation packages labelled

Download the appropriate onefor your CPU.

If it didn't ask you, it put it in Downloads. Make a note of this location, you'll need it for the next step.

<!-- We can probably delete this bit as I've included the link above I'll include one more link that tells you how to take a screenshot on a Chromebook, so you can post a screenshot of any difficulty you have. It is

=== What you need to do now is to install the .deb file that you downloaded. ===We don't need to do this in Linux, it's simpler to do it from Chrome.<!-- Do you know where the file was saved?

Either way, now n--> Now open the Chrome Files App, and go to the folder with the Oscar package that you downloaded. It will show as a .deb file that you downloaded(eg Oscar_blah_blah.deb)

A mouse right click is sometimes useful, and you can get the same effect by holding down the Alt key and clicking in the touchpad. If a mouse right click is required in these instructions, it will be shown as Alt-touchpad-click and as Mouse-right-click. Pick one, don't do both. mjphyi has noticed that although the above paragraph is correct, right clicking isn't going to be required when installing Beta-2 or later up to this point. It WILL be requiredas required as part of importing for the first time, and it will be repeated there, but maybe it'll disappear from here. Note that each line is indented, causing that text to appear in a box - useful for asides like this which interrupt the flow of the narrative.

You may have made a profile before, and you may have imported from an SD Card before, but importing from an SD card on Chrome OS for the first time is quite different, so do '''NOT''' try it until you have gone back to <!-- the page above this one, Don't use this sort of terminology else people will quickly get lost in the wiki. Put the section name and a link --> and read all of the instructions about how to do it.
