+When you get added to the lbryio github org, you'll automatically be subscribed to all of our repos. This creates a lot of noise in your inbox, and there's no good way to turn this off. Here's how you can deal with it.
+
+## Option 1: Before you get added
+
+If you happen to find this page before you get added to the org, you can temporarily disable automatic watching of repos. Go to [your notification settings](https://github.com/settings/notifications) and uncheck the "Automatically watch repositories" checkbox. You can re-check this box after you've been added to the org.
+
+## Options 2: After you've been added
+
+If you've already been subscribed to all the notifications, here's what to do. First go to https://github.com/watching and run the following code in your browser console. This will unwatch all the lbryio repos that you're subscribed to.
+
+```js
+Array.prototype.forEach.call(document.querySelectorAll('.js-subscription-row'), function(el, i){
+  const isYourOrganisation = el.querySelectorAll("a[href^='/lbryio']");
+  if(isYourOrganisation.length){
+    const button = el.querySelectorAll('button[type="submit"]')[0];
+    if (button.innerHTML == "Unwatch") {
+      button.click();
+    }
+  }
+});
+```
