+#### First synchronization of new project
+
+It is recommended to start first synchronization from Flow side. 
+
+Please create new project there, update its Project tracking as requested (`Project Actions` > `Tracking Settings`).
+
+![Flow Project Tracking](assets/shotgrid/project_tracking.png)
+
+In this example it is shown that all items of `Asset` and `Sequence` type will be synchronized to flat 
+hierarchy in AYON, `Shot` items will be parented under `Sequence`.
+
+Please provide `code` value for this project for AYON start recognizing it. 
+(Dropdown next to your profile picture > `Projects`. You might need to add `Code` column to be visible.)
+
+No go back to your AYON server.
+
+Create new project via `Project Settings` > `Add New Project`, it is recommended to use same name and code values as in Flow.
+Use `SG` Anatomy preset you set previously (see higher for more details).
+
+Go to `Studio Settings` > `Shotgrid`, click on `Populate Table`.
+This should list all available projects on AYON server and Flow.
+
+:::note Note
+`Populate Table` requires at least `Processor` service to be running!
+:::
+
+Hit `Shotgrid -> AYON` button (if it is grayed out, it means that project is missing `code` in Flow).
+
+To keep both sides synchronized you need to:
+- in AYON go to `Project Settings > Anatomy` (of synchronized project) and toggle `Shotgrid Push`
+- in Flow go to `Projects` and toggle `Ayon Auto Sync` (you might need to add this column to be visible)
+
+:::note Note
+Synchronization between Flow and AYON started as unilateral from Flow. Two way synchronization features
+are being added, but parity is not achieved yet. It is recommended to start from Flow for now.
