 ## Extracting
 If you have not already extract the distribution and cd into the cactus directory:
 ```
-tar -xzf cactus-bin-v2.6.10.tar.gz
-cd cactus-bin-v2.6.10
+tar -xzf cactus-bin-v2.6.11.tar.gz

 ## Setup
 
 To build a python virtualenv and activate, do the following steps. This requires Python version >= 3.7 (so Ubuntu 18.04 users should use `-p python3.8` below):
 ```
-virtualenv -p python3 venv-cactus-v2.6.10
-printf "export PATH=$(pwd)/bin:\$PATH\nexport PYTHONPATH=$(pwd)/lib:\$PYTHONPATH\n" >> venv-cactus-v2.6.10/bin/activate
