 This library provides constant time finite field primitives for implementation of elliptic curve cryptography.
 
-Warning ⚠️: The library is in development state.
+Warning ⚠️: The library is in development state and cannot be used at the moment
+            except as a showcase or to start a discussion on modular big integers internals.
 
 ## Installation
 
 You can install the developement version of the library through nimble with the following command
 ```
-nimble install https://github.com/status-im/nim-constantine@#master
+nimble install https://github.com/mratsim/constantine@#master
 ```
