+Template.UntilLoop.py
+---------------------
+
+### Synopsis
+Template for a Python `until` Loop
+
+---
+
+### Description
+
+Template for a `until` loop in Python.
+
+---
+
+### Examples
+> EXAMPLE 1
+
+```PowerShell
+Template.UntilLoop.py -Condition "True" -Body "print('This happens once')"
+```
+
+---
+
+### Parameters
+#### **Condition**
+The Loop's Condition.
+This determines if the loop should continue running.
+This defaults to 0 > 1, so that the loop only occurs once
+
+|Type      |Required|Position|PipelineInput        |
+|----------|--------|--------|---------------------|
+|`[String]`|false   |1       |true (ByPropertyName)|
+
+#### **InitialCondition**
+The Loop's Initial Condition.
+Since Python does not have a `do` loop, this needs to be any truthy condition for the loop to run.
+
+|Type      |Required|Position|PipelineInput        |
+|----------|--------|--------|---------------------|
+|`[String]`|false   |2       |true (ByPropertyName)|
+
+#### **Body**
+The body of the loop
+
+|Type      |Required|Position|PipelineInput        |
+|----------|--------|--------|---------------------|
+|`[String]`|false   |3       |true (ByPropertyName)|
+
+#### **BodyIndent**
+The number of spaces to indent the body.
+By default, two.
+
+|Type     |Required|Position|PipelineInput        |
+|---------|--------|--------|---------------------|
+|`[Int32]`|false   |4       |true (ByPropertyName)|
+
+#### **Indent**
+The number of spaces to indent all code.
+By default, zero
+
+|Type     |Required|Position|PipelineInput        |
+|---------|--------|--------|---------------------|
+|`[Int32]`|false   |5       |true (ByPropertyName)|
+
+---
+
+### Notes
+There is not a proper `do` or `until` loop in Python, so we have to be a little creative.
+
+This will produce a while loop where the `-InitialCondition` should always be true,
+and the `-Condition` will be checked at the end of each iteration.
+
+If the `Condition` is true, then the loop will break.
+
+---
+
+### Syntax
+```PowerShell
+Template.UntilLoop.py [[-Condition] <String>] [[-InitialCondition] <String>] [[-Body] <String>] [[-BodyIndent] <Int32>] [[-Indent] <Int32>] [<CommonParameters>]
+```
