+### Manual Install
+
+If you wish to install Havoc client side modules manually it is quite easy. The
+Havoc app provides a script manager tab where modules can be loaded. This can
+be accessed through Scripts > Scripts Manager.

+
+### Extensions tab inside of the GUI
+
+The havoc python API also includes a store where you can download directly inside
+of havoc different extensions for the front-end. This interface is accessible to
+users through Attack > Extensions.
+
+#### Contribute your extensions to the store
+
+Currently the store is located on the [following repo](https://github.com/p4p1/havoc-store)
+more details can be found directly there on publishing your own module. Make sure
+that your module does not change the directory of Havoc with *os.chdir* to not
+break dependencies. You can publish your module by doing a pull request directly
+on the repo after editing the json file that is downloaded by the front-end inside
+of public/havoc-modules.json. A json entry should look like the following:
+```
+  {
+    "title":"<your title>",
+    "description":"<Your description>",
+    "author":"<Your username on github>",
+    "link":"<the link to the module>",
+    "preview":"<The preview image of the module",
+    "category": {
+        "BOF": false,
+        "Console": false,
+        "Graphical": true
+    }
