Quality Settings

In Edit > Project Settings > Quality, you can adjust which quality settings are available on which platform and what each of those quality settings changes as well. For more information on what these quality settings can do, please visit https://docs.unity3d.com/Manual/class-QualitySettings.html.

Unity Services

There's a lot of things Unity can do for you, with Analytics and Multiplayer, and etc, but we're only going to talk about Collaboration and Cloud Build for now.

Cloud Build

Collaborate

Activating this option for your project will allow you to share editing rights for your project with more Unity users (after you give them permission). It can also allow you to upload your project to the cloud to use on another computer, as long as you log into your account. To activate, go to the Window menu and select Services. Select an Organization with the provided dropdown menu. An organization is all the people you're going to share the project with, once it is created you can start inviting other Unity users to join. Even if you're keeping the project to yourself you do need to make one in order to use the Collaboration tool. Once that's done setting up, the Collab button, in the upper left corner will have a blue arrow pointing up, this means that you have new changes to upload to the cloud. When you want to upload you changes, click the Collab button, and there should be an "Update Now!" option, and a text box you can use to add a message to explain to your collaborators what you've changed this time.

A green check mark means you're up to date with all the changes and you haven't made, or saved, any new changes that might need to be uploaded.

An orange down arrow (as in ) means that somebody else uploaded some changes to the project that you don't have yet. If you click on the Collab button when that's true, you can choose to get all the updates, but it might warn you that there are some file conflicts. This can be caused by you having made a new file with some name and if with the incoming changes, there is another file with the same name, they will conflict. A conflict may also happen if you made some changes to a specific file and the new changes that you have yet to download change the same file. To resolve this, you may want to see where the conflict occurs and what the differences between the files involved is.

Build & Run

If you've been following along you should have your quality settings all the way you wanted them.

Now you should check File > Build Settings and make sure everything looks right in there, such as what scenes you want included, your target platform, whether or not this is a development build vs being official and stable. Then you can pick build, or build and run if you'd like to test it and your system is one of the targeted platforms. You could also set up Unity Cloud Build so your builds get pushed to Unity's cloud database for your account.
