 # Balancer AMM cadCAD model
 This repo contains the Python code, input data samples and several Python notebooks allowing users to simulate Balancer pools.
 
-It is ongoing work and repo updates all the time:
+It is ongoing work and repo updates all the time.

+Roadmap:
 
 **Phase 1:** 
 Phase 01 goal is to provide Balancer AMM functionality in a cadCAD model and run a set of simulations with historical data to demonstrate model operation and produce educational materials helping to gain in-depth understanding and intuition of Balancer AMM and AMMs in general.
 
 **Phase 2:** 
 More complex cases, including: agents behavior, dynamic weights changing in the AMM equation, particular cases for EthicHub and PowerPool
