 # Introduction
 
-describe notebook structure and what this thing does
+The user facing part of the software consists of 5 Jupyter notebooks representing different steps of the workflow:
+1. Definition of curing parameters
+2. Definition of component manufactoring defects
+3. Configuration of operational parameters
+4. Execution of simulation and visualization of results
+5. Example workflow explaining python simulation package with no UI
+
+The 3 different input steps are separate from each other and do not depend on results from other input steps. Once desired input data has been defined, the simulation can be started from the fourth notebook.
 
 # Curing Input
 
-first notebook
+![step_1](uploads/3f8459d365168ffa71ec4e7a3ce58a6e/step_1.png)
+
+Fibre composite material hardening process during manufactoring. 
+
+Necessary user input:
+- Temperature timeline of curing chamber
+- Fibre volume content of material in \%
 
 # Component manufactoring defects
 
-second notebook
+![step_2](uploads/09919ea2489263b9989b5410e1d75066/step_2.png)
+
+Compontent manufactoring defects placed on the 3D mesh that is also used for later simulation. Defects are localised via cell and layer IDs.
+
+Possible faults to place:
+- Missing layer
+- Fibre misalignment in layer
+- Wrong thickness of layer
+- Waviness in layer material
 
 # Operational parameters
 
-third notebook
+![step_3](uploads/58ca4dadd38e6d3f7dbacc043524f817/step_3.png)
+
+Environmental and resulting wind turbine conditions during structural simulation. This step uses a number of predefined wind data input sets the user can select from.
+
+Necessary user input:
+- Average wind speed in m/s
+- Duration of simulation in years
 
 # Execution and visualization of results
 
-fourth notebook
+Select from input data sets created in previous steps to start simulation. Completed previous and currently running simulations are displayed in pyiron job table.
+
+The results of finished simulations can be rendered in this screen, broken down by material and layers of wind turbine.

 # Python workflow example
 
-fifth notebook

+The final notebook is a practical example and tutorial how to use the underlying 'sensotwin' python package to run the workflow without the Jupyter widget UI. It describes the individual steps as they are represented in the UI notebooks in purely python code in case automation is desired.
