+#1. Welcome to Posh
+
+#.Silent Clear-Host
+
+# Posh improves the PowerShell experience.
+
+# It enhances PowerShell formatting, and makes the shell easier to script.
+
+# For a simple example, just echo the variable $Posh
+
+$Posh
+
+# Let's take a quick tour of some of the ways Posh makes PowerShell cooler.
+
+#2. Enhanced Formatting
+
+#.Silent Clear-Host
+
+#2.1. File Colorization and Icons
+
+# Posh shows files in color with (hopefully) helpful icons and clickable links.
+
+Get-Module Posh |
+    Split-Path |
+    Get-ChildItem
+
+# Posh's icons do not require NerdFonts, and will be ignored in favor of Terminal-Icons, if that's what you prefer.
+
+#.Silent Clear-Host
+
+#2.2  Get-Command in Color
+
+# Posh also updates the formatter for Get-Command.
+
+# It slims the output to just the Name and the Module,
+# and colorizes the Name based off the verb.
+
+Get-Command -Module Microsoft.PowerShell.*
+
+#.Silent Clear-Host
+
+#2.3. Get-Member in Color
+
+# Get-Member is one of the three most useful commands in PowerShell
+
+# Posh lets you see it in color:
+
+Get-Command | Get-Member
+
+#.Silent Clear-Host
+
+#2.4 Reflection formatting
+
+# Posh also makes it easy to explore reflection.
+
+# Just pipe a type to Format-Custom.
+
+
+[int] | Format-Custom
+
+# By default, this only shows you short set of information about just that type.
+
+# To see _everything_ about an object, use something like
+
+[int] | Format-Custom -View System.Type.Full
+
+
+# This also works for generic types.
+
+[Collections.Generic.Dictionary[string, PSObject]] | 
+    Format-Custom -View System.Type.Full
+
+#2.5 Colorized XML
+
+#.Silent Clear-Host
+
+# Posh also makes XML more colorful in the console.
+
+Invoke-RestMethod https://pssvg.start-automating.com/Examples/HelloWorld.svg
+
+#2.6 Colorized Regular Expressions
+
+#.Silent Clear-Host
+
+# Regular Expressions are also syntax highlighted, helping us all hopefully understand them better.
+
+[Regex]::new('
+(?<NameOfCaputre>Pattern) # Comment
+','IgnoreCase,IgnorePatternWhitespace')
+
+
+#2.7 Get-Process heatmap
+
+# Posh also makes the formatter for Get-Process show a heatmap of various properties.
+
+Get-Process -id $pid
+
+#2.8 TimeSpans and TimeZones
+
+#.Silent Clear-Host
+
+# Posh also simplifies the display for TimeZones and Timespans
+
+New-TimeSpan -Hours 24 -Minutes 30 -Seconds 15
+
+# We can also display timespans in their ISO format!
+
+New-TimeSpan -Hours 24 -Minutes 30 -Seconds 15 |
+    Format-Custom -View ISO-8601
+
+
+# TimeZones also get more readable by trimming the number of displayed properties.
+
+Get-TimeZone
+
+# We only show the ID and DisplayName.
+
+# We also add a .LocalTime for ease of use.
+
+# This makes a simple PowerShell command console World Clock.
+
+Get-TimeZone -ListAvailable
