Quick start guide for PnP PowerShell

It is quite easy and quick to set up PnP PowerShell on a local system and start using it. Considering that PnP PowerShell has been gaining a lot of momentum among Devs and Admins, I thought it would be good to have a post for everyone’s reference.
So why PnP PowerShell? Because it is the recommended and most updated PowerShell module for IT Pros to work on SharePoint Online, SharePoint on-premise and Office 365 Groups. It allows us to remotely maintain a SharePoint Online and Office 365 tenancy as we will see below.
Installation:
First, we have to make sure that we have the latest and greatest version of PowerShell (at least >= v4.0) on the system. We can simply check it using the following command $PSVersionTable.PSVersion which will give the output below.

If your version isn’t sufficient, then go to this link to upgrade – https://www.microsoft.com/en-us/download/details.aspx?id=40855. Since there are OS requirements accompanied with PowerShell, please make sure to check the System Requirements in order to make sure the OS matches the specs.
Also, I would recommend installing SharePoint Online Management Shell because there are various Tenant commands that you may not find in PnP PowerShell. The link can be found here – https://www.microsoft.com/en-au/download/details.aspx?id=35588. Again, make sure to check the System Requirements in order to make sure the OS matches the specs.
After you have the proper PowerShell version, run the following commands to install the PnP PowerShell module depending on if you’re using the Online or On-Premise version.  You only need to install the version(s) you need to interact with (no need to install on premise versions if you’re only working online).

It will likely take few mins to run and complete the above command(s).
Getting Started Guide:
To start using PnP PowerShell, first we will have to understand how PnP PowerShell works.
PnP PowerShell works in the context of the current Connection the site it is connected to. Assuming it is connected to a Site Collection, all commands refer by default to that Site Collection. This is different from SPO commands which require you to have Tenant Admin rights. A benefit of the PnP approach is that you can have separate Admin personnel to manage separate site collections or sites if needed.
Overview of Basic SharePoint Operations with PnP PowerShell
1. Connect to PnP Online

Connect-PnPOnline -Url

In the above case, if you are not given a prompt for entering your credentials, then create a credential object and pass it to the Connect command (as seen below).

$user = ""
$secpasswd = ConvertTo-SecureString "" -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential ($user, $secpasswd)
Connect-SPOnline -url $siteAdminURL -Credentials $mycreds

2. Get the web object using Get-PnPSite and then get the subsites in it

## For Site Collection (root web)
$web = Get-PnPSite 
## For Sub web
$web = Get-PnPWeb -Identity ""

Remember, PnP works in the context of the current connection.
3. To work on lists or objects of the site, use the “Includes” parameter to request them or else they will not be initialized.

$web = Get-PnPSite -Includes RootWeb.Lists

After you get the list object, you can traverse it as needed using the object.
4. To work on list items, you must request the list items and same goes for updating the items.

$listItem = Get-PnPListItem -List "Site Assets"

Set-PnPListItem -List "Site Assets" -Identity 2 -Values @{"" = ""}

So, as we saw above, we can use PnP PowerShell to maintain SharePoint assets remotely.
Please feel free to let me know if there are any specific questions you may have regarding the approach above and I will post about those as well.
