 - Install packages in the training and version control directories in the pipeline folder (dev version if applicable)
 - Install pre-commit to enable pre-commit hooks
 
-To use the environment, run `source .dev_env_pipeline/bin/activate`.
+To use the environment, run `conda activate dev_env_pipeline`
