-In some exploitation scenarios such as local privilege escalation, command execution, write-only attacks, SQL Injections, etc, it is very likely that you have to upload one or more malicious files in order to gain control of the target machine. Well, a smart attacker shouldn't leave anything behind, so if a module needs to drop something onto the file system, it's important to remove it right after the purpose is served.
+### Introduction
 
-Metasploit offers a way to manage these soon-to-be-removed files, and it's simple to use.

+In some exploitation scenarios such as local privilege escalation, command execution, write-only attacks, SQL Injections, etc, it is very likely that you have to upload one or more malicious files in order to gain control of the target machine. Well, a smart attacker shouldn't leave anything behind, so if a module needs to drop something onto the file system, it's important to remove it right after the purpose is served. And that is why we created the FileDropper mixin.
+
+### Examples
+
+The FileDropper mixin is a file manager that allows you keep track of files, and then delete them when a session is created. To use it, first to include the mixin like so:
+
+```ruby
+include Msf::Exploit::FileDropper
+```
+
+Next, tell the FileDropper mixin where the file is going to be after a session is created by using the ```register_file_for_cleanup``` method. Each file name should either be a full path, or relative to the current working directory of the session. For example, if I want to upload a payload to the target machine's remote path: ```C:\Windows\System32\payload.exe```, then my statement can be:
+
+```ruby
+register_file_for_cleanup("C:\\Windows\\System32\\payload.exe")
+```
+
+If my session's current directory is already in ```C:\Windows\System32\```, then I can simply do:
+
+```ruby
+register_file_for_cleanup("payload.exe")
+```
+
+If you wish to register multiple files, you can also provide the file names as arguments:
+
+```ruby
+register_file_for_cleanup("file_1.vbs", "file_2.exe", ""file_1.conf")
+```
+
+Note that if your exploit module uses ```on_new_session```, you are actually overriding FileDropper's ```on_new_session```.
