 This will be faster if you first install the package `mamba`. To do this:
 
-        conda install -c conda-forge mamba
+        conda create -y -n mamba
+        conda activate mamba
+        conda install -y -c conda-forge mamba

 If you choose to use `mamba` then you can install the `geog0111` environment with:
 
-        mamba env create --force -n geog0111 -f environment.yml
+        mamba env create -y --force -n geog0111 -f environment.yml
         
 This may take minutes/tens of minutes. If you do not have `mamba`, just use `conda` (Warning: this is *much* slower):
 
-        conda env create --force -n geog0111 -f environment.yml
+        conda env create -y --force -n geog0111 -f environment.yml
