 	Reset API key
 	Reset user password
 
+- The API endpoint is http://api.unps.us/index.php (I might code in something else eventually)
+- Usage of the API endpoint:
+	- POST to index.php
+	- GET is supported (not for images) - Be wary about submitting passwords this way
+	- Use form on index.php
+	
+	- This has basic support, JSON support planned
+	- Function name (short, imgup, delshort, etc)
+	- Your APIKey
+	- data:
+		- If using Short functions:
+			- link
+			- link password (optional, if custom password on link creation, same one required on link deletion)
+			- reason (only accepted for report link)
+		- If using Image functions:
+			- Uploading:
+				- username
+				- comment
+				- tags (space separated only)
+				- private (1 or 0 boolean - If 1, image is private, else, image is public)
+				- Imagedata (multipart/formdata - some type of array within an array, or something)
+			- Deleting:
+				- username
+				- image name
+			- Editing:
+				- username
+				- image name
+				- private (1 or 0 boolean - If 1, image is private, else, image is public)
+		- If registering:
+			- New User:
+				- username
+				- password (stored using HashPass - http://p.unps.us/HashPass.php)
+				- email
+			- New API User (recommended but not required to have existing user account): 
+				- appname
+				- email
+		- If resetting:
+			- Reset APIKey:
+				- appname
+				- email
+				- resetkey
+			- Reset Password:
+				- email
+				- new password
+
+	- All Returns:
+		- These are returned in plain text, JSON support planned - the first one is the expected result
+		- mysqli_* errors are also possible, but should be rare
+		- shorten:
+			- Shortened: http://unps.us/?l=[SHORT LINK]
