+
+### Pre-Requisites
+
+
+- The [*latest C++ Redistributable*](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#latest-supported-redistributable-version) from Microsoft.
+    - Eden will not even launch without it see [*Eden Fails to Launch*](./EdenFailsToLaunch.md) for more information.
+- Firmware dumped from your console
+- Keys extracted from your console
+- Games dumped from your console
+- Internet Connection
+
+---
+
+## Steps
+
+1. Download either the *Stable* or *Nightly* Eden application.
+    <aside>
+    
+    ***TIP***:  If you have questions about the requirements, architectures, or general information surrounding what release you need - see the [*Basics Guide*](./Basics.md) and [*Architectures Guide*](./Architectures.md).
+    
+    </aside>
+2. Extract the contents to wherever you want to store the program on your computer. 
+    <aside>
+    
+    ***TIP***: If you want to run Eden completely portable (everything is stored in the folder you extracted it to) - create a folder called **user** if it is not there by default.
+    
+    </aside> 
+3. Run ***Eden.exe*** to launch the program.  
+    
+    <aside>
+
+    ***INFO***: You may get a “*Windows protected your PC”* SmartScreen message that appears.  This is just Windows Defender saying it did not recognize the application and did not run it - Eden is completely safe.  Click **More info** and then **Run anyway** to dismiss this message.
+    
+    </aside>
+4. Eden will now launch and notify you about missing Decryption keys. Close the dialog box by hitting **OK**.
+5. Navigate to **Tools → Install Decryption Keys**, navigate to the folder containing your key files and select the file, you should only be able to select one.
+6. Navigate to **Tools → Install Firmware**, *Select **From Folder*** or ***From ZIP*** - depending on how your firmware is stored, navigate to where it is stored and select it.    
+7. Double-Click the main window to add the folder containing your games.
+8. Go to *Emulation > Configure > Input* and set up your controller of choice. Click **OK** to close the dialog window.
+9. Double-Click a game to run it.
