+## Focus
+The repository contains a bundle of jupyter notebooks explaining the basic
+concepts needed for modeling of bond and cracking behavior in brittle-matrix
+composites. Applications are demonstrated on pullout tests and bending tests
+of steel and carbon reinforced concrete composites that have been developed for
+different types and scales of reinforcement bridging and pullout actions. 
+Considered types of reinforcement include long, contiuous bars, textile fabrics, 
+reinforcing sheets and short fiber. Jupyter notebooks serve as the top layer of numerical and 
 semi-analytical models provided in the BMCS Tool Suite.
 
+## Structure
 Each notebook contains a theoretical preamble which is accompanied 
 by executable form of the derived formulae expressed within sympy package. 
 Then, numerically executable functions are generated from the symbolic 
 derivation. Large models, including nonlinear finite-element simulations
 are realized with the help of numpy package. They serve as a basis for interactive 
-execution of the model providedat the end of the notebooks. The interaction 
+execution of the model provided at the end of the notebooks. The interaction 
 with the model is implemented using the ipywidget/matplotlib packages.
 
-Prerequisites: The anaconda suite is required for installation. See a
-minimum set of required packages in environment.yml file.
-
-The entry point to the jupyter suite is the index.ipynb notebook.
+## Prerequisites 
+To execute the notebooks locally install the anaconda suite. Required packages
+are specified in the environment.yml file. The entry point to the jupyter suite 
+is the index.ipynb notebook.
 
+## Binder
 The notebooks can be open also in the clouds without any local installation
 using the binder service. It takes a while for the repository image to build up.
