 # TODO
 
+# Flow types
+
+* Graph
+* Pipeline
+
+## Graph
+
+Graph will have one output and several inputs, a graph is commanded by the output node
+like a function the node runs by fetching inputs and processing them.
+
+* Several inputs
+* One output
+* Graph is started by the last node
+* Process will follow from current fetching the input nodes
+* Each input can only have one source
+* Fetch result from any node
+
+computational graphs can have several purposes but the primal goal was machine learning
+and have a flow of tensors
+
+## Pipeline
+
+Pipeline will have a single input and output and its commanded by the first node
+when a node is finish it will trigger the next nodes with data generated by the node
+
+* One input
+* One output
+* Nodes trigger other to process
+* One input can have several sources, a node can send to several outputs
+* Nodes are dependend on input, process should start from the initial pipeline node
+
+Pipelines can also have several purposes but started with the idea of creating
+some kind of CI where we can graphically see nodes processing,
+from build to staging
+
 # Minimal idea
 
-UI to create multipurpose tensorflow alike graphs,
+UI to create multipurpose flow graphs,
 upload to the server
 pass inputs and do training
 fetch model and use it with new inputs
