+# EconomistWorldInBriefBridge
+
+In May 2024, The Economist finally fixed its paywall, and it started requiring authorization. Which means you can't use this bridge unless you have an active subscription.
+
+If you do, the way to use the bridge is to snitch a cookie:
+1. Log in to The Economist
+2. Open DevTools (Chrome DevTools or Firefox Developer Tools)
+2. Go to https://www.economist.com/the-world-in-brief
+3. In DevTools, go to the "Network" tab, there select the first request (`the-world-in-brief`) and copy the value of the `Cookie:` header from "Request Headers".
+
+The cookie lives three months.
+
+Once you've done this, add the cookie to your `config.ini.php`:
+
+```
+[EconomistWorldInBriefBridge]
+cookie = "<value>"
+```
