 ## Building and installing
 
-The *environment.yml* file contains the python libraries for using the **TNBS**. You can build the environment using conda (new environment called tnbs_test will be created):
+There are two ways for installing mandatory Python libraries for using the **TNBS** code: using the *environment.yml* file or the *requirements.txt* file.
 
+* The *environment.yml*: this file contains all the mandatory libraries for executing the **TNBS** code including the different *jupyter-notebooks* presented in the TNBS repository. For installing them the following conda command (new environment called tnbs_test will be created):
     conda env create -n tnbs_test -f environment.yml
-
+* The *requirements.txt*:  this file contains the mandatory libraries for executing the **TNBS** code except the *jupyter-notebooks* (jupyter notebooks libraries should be installed manually). For installing them the following command can be used:
+    pip install -r requirements.txt
 
 ## Repository organisation
 
 The different **BTC** are located inside the **tnbs** folder:
 
-1. *BTC_01_PL*: Software implementation for the **BTC** of the *Probability Loading kernel*. See deliverable: **T01: Benchmark for Probability Loading Algorithms**
