+I'm considering including management scripts in this vault,
+but I'd generally prefer to keep it content only.
+Ideally I could do anything I'd use a script for with a plugin,
+but they have their limitations.
+Eventually I should [[learn-to-write-obsidian-plugins]],
+but for now here's a useful cmdlet I wrote a while ago but misplaced.
+
+```powershell
+function Import-Markdown {
+    [CmdletBinding()]
+    param(
+        [Parameter(Mandatory)]
+        [string]$Path
+    )
+    try {
+      $command = Get-Command ConvertFrom-Yaml -ErrorAction "Stop"
+    }
+    catch {
+      throw "no YAML conversion module installed. Try ``Install-Module powershell-yaml``."
+    }
+ 
+    $content = Get-Content -Path $Path -Raw
+    $pattern = [Regex]'(?ms)^---\s*(.*?)\s*---\s*(.*)$'
+    $match = $pattern.Match($content)
+    if ($match.Success) {
+        $frontmatter = $match.Groups[1].Value
+        $body = $match.Groups[2].Value
+    }
+    else {
+        $frontmatter = ''
+        $body = $content
+    }
+ 
+    return [pscustomobject]@{
+        frontmatter = $frontmatter | ConvertFrom-Yaml
+        body        = $body
+    }
+}
+```
+
+That match expression is bizarre,
+and the whole thing needs better error handling,
+but it works.
+
+A `Where-Markdown` for filtering by tags
+and a `{Verb}-Markdown` for modifying tags
+would be idiomatic.
