 ## 2 ways to download it:
 
-   1) typing : 
-
-      >  python -m pip install copernicusmarine
-
+   1) typing :
+      ```console
+      python -m pip install copernicusmarine
+      ```
 
 
    2) Use of conda/mamba package (replace conda by mamba command below)
 
       * Install a dedicated environment, by default named cmt_1.0 . First, you need to copy the file copernicusmarine_env.yml from the directory Forecast_tools/CopernicusMarineToolbox/
-         > conda env create -f copernicusmarine_env.yml
-     
-        **Note** that you can use micromamba instead of mamba to install the python environment
-         
 
-Firstly, you need to activate the environment cmt_1.0 :
+         ```console
+         conda env create -f copernicusmarine_env.yml
+         ```
