## F.A.Q.
##WHY?

Since the migration from 4chan to 8kun has been completed, it's now necessary to install this conversion script to view recaps pointing to 4chan (when the thread was still hosted there). It essentially works like the previous script, but with additional steps. 


##How do I install it?"

Install Guide:
 1. How to Install Scripts in Firefox/Chrome (Tampermonkey, etc.):
        -Get a Userscript Manager:
        -Firefox/Chrome: Install Tampermonkey (Chrome Web Store / Firefox Add-ons).
        -Alternatives: Violentmonkey or Greasemonkey (same steps).

 2. Import the Script into Tampermonkey:
        -Open Tampermonkey’s dashboard (click its icon → "Dashboard").
        -Go to the "Utilities" tab.
 3. Paste the ##User Script code into the box.
        -Under "Install from clipboard", click "Import" → paste the code from above → "Install".
 4. Click "Install" or "Confirm".
