+#### Direct download:
+All commands remain the same, the only difference when you download from source is how you load scripts.
+You will need to dot source the Voicemeeter.ps1 since you won't have it installed as a module
+
+Instead of `Import-Module Voicemeeter` use `. .\lib\voicemeeter.ps1` (from repository root)
+
+and call remote class directly, so: `$vmr = [Remote]::new('banana')`
+
+Where you pass it a Voicemeeter type argument. Type can be one of:
+- basic
+- banana
+- potato
+
+Simple example if using from source:
+
+```powershell
+. .\lib\voicemeeter.ps1
+
+try {
+    # Pass a Voicemeeter type as argument
+    $vmr = [Remote]::new('banana')
+
+    # Set strip and bus params
+    $vmr.strip[0].mono = $true
+    $vmr.strip[0].mono  '=> $true'
+    $vmr.bus[1].mute = $false
+    $vmr.bus[1].mute    '=> $false'
+
+    # Set macrobutton with id 4, mode state to 1
+    $vmr.button[4].state = $true
+    $vmr.button[4].state    '=> $true'
+}
+finally { $vmr.Logout() }

 ## Use
 When you instantiate Remote class you will automatically be logged in. Use a
 try finally block to ensure you logout at the end of your code.
 ```powershell
-. $PSScriptRoot\lib\voicemeeter.ps1
+Import-Module Voicemeeter
 
 try {
-    # pass a Voicemeeter type to class Remote
