 Initializes a `struct PtpRuntime`. The struct is pretty small. This allocates the a large buffer to `r.data`.
 You may also set r.connection_type to one of `enum PtpConnType`.

-1. Send a *command packet* with up to 5 parameters
-2. An optional data packet (the data phase)
-3. A response packet(s) is recieved from the camera.

-For data to be sent to the camera, a data packet can be sent following  
-the command packet. The camera should know when to expect this.  
-
-- Each packet sent to the camera has a unique transaction ID (see PtpBulkContainer.transaction)
-- The operation code (OC) is an ID for each command, and determines how the camera will expect and send back data.
-- In a response packet, the response code (RC) is placed in the PtpBulkContainer.code field

 ## JSON Bindings
 Camlib provides a JSON frontend that can easily be ported to higher level programming languages,
 like Java, Javascript, or Python.

+# Documentation For Camlib
+- PDF Reference for PTP and MTP: https://www.usb.org/document-library/media-transfer-protocol-v11-spec-and-mtp-v11-adopters-agreement
+- PTP/IP has no free public reference :(
+
+Terminology:
+- initiator: the computer that sends commands (laptop, phone, PC)
+- responder: the computer that responds to commands (the camera)
+
+## Quick Overview of PTP Standard
+### To issue a command to the device
+1. Send a *command packet* with up to 5 parameters
+2. An optional data packet (the data phase)
+3. A response packet(s) is recieved from the camera.
+
+For data to be sent to the camera, a data packet can be sent following  
+the command packet. The camera should know when to expect this.  
+
+- Each packet sent to the camera has a unique transaction ID (see PtpBulkContainer.transaction)
+- The operation code (OC) is an ID for each command, and determines how the camera will expect and send back data.
+- In a response packet, the response code (RC) is placed in the PtpBulkContainer.code field
+
+## PTP/IP
+PTP/IP is the variant of PTP designed to be used on TCP.
+
+A standard request to the responder is as follows:
+1. Command request (`PTPIP_COMMAND_REQUEST`) send to responder
+2. If sending data payload:
+	- Set the `data_phase` field in the initial `PTPIP_COMMAND_REQUEST` packet
+	- Send data start packet (`PTPIP_DATA_PACKET_START`), contains data length
+	- Send data end packet (`PTPIP_DATA_PACKET_END`), which includes the actual data
+2. If not sending payload to responder, then, wait for response
+
+Response is either:
+- `PTPIP_DATA_PACKET_START` packet followed by `PTPIP_DATA_PACKET_END`, and finally a `PTPIP_COMMAND_RESPONSE` packet
+- Just a `PTPIP_COMMAND_RESPONSE` packet
