 ### Steps
 
+#### import wandb
+
+- minimal code should be run on import
+
 #### wandb.init()
 
-- Creates a Run object (specifically RunManaged)
+User Process:
+
+- Calls internal wandb.setup() in case the user has not yet initialized the global wandb state
+- Sets up notification and request queues for communicating with internal process
+- Spawns internal process used for syncing passing queues and the settings object
+- Creates a Run object `RunManaged`
+- Encodes passed config dictionary into RunManaged object
+- Sends synchronous protocol buffer request message `RunData` to internal process
+- Wait for response for configurable amount of time.  Populate run object with response data
+- Terminal (sys.stdout, sys.stderr) is wrapped which sends output to internal process with `RunOutput` message
 - Sets a global Run object for users who use wandb.log() syntax
+- Run.on_start() is called to display initial information about the run
 - Returns Run object
 
-TODO(jhr): finish this
+Internal Process:
+
+- Process initialization
+- Wait on notify queue for work
+- When RunData message is seen, queue this message to be written to disk `wandb_write` and sent to cloud `wandb_send`
+- wandb_send thread sends upsert_run graphql http request
+- response is populated into a response message
+- Spin up internal threads which monitor system metrics
+- Queue response message to the user process context
+
+#### run.config attribute setter
+
+User Process:
+
+- Callback on the Run object is called with the changed config item
+- Run object callback generates ConfigData message and asynchronously sends to internal process 
+
+Internal Process:
+
+- When ConfigData message is seen, queue message to wandb_write and wandb_send
+- wandb_send thread sends upsert_run grapql http request
+
+#### wandb.log()
+
+User process:
+
+- Log dictionary is serialized and sent asynchronously as HistoryData message to internal process
+
+Internal Process:
+
+- When HistoryData message is seen, queue message to wandb_write and wandb_send
+- wandb_send thread sends file_stream data to cloud server
+
+#### end of program or wandb.join()
 
+User process:
 
-## Sync details
+- Terminal wrapper is shutdown and flushed to internal process
+- Exit code of program is captured and sent synchronously to internal process as ExitData
+- Run.on_final() is called to display final information about the run
