+!!! tip
+    Time to time it is good to clean up the cached packages (there can be a lot of them). You can do it with the following command:
+
+    ```bash
+    conda clean --all
+    ```
+
+!!! tip
+    By default conda environments will be installed to the home directory of the user (`~/miniconda3/envs`). This is not ideal since the home directory is located on the SSD and the space is limited. Instead, you should install the environments to the NVMe disk, and make a symbolic link to the custom location to easily activate such environment. Here is how you can do it:
+
+    ```bash
+    # Create environment
+    conda create --prefix /home/nvme/$USER/.envs/$MY_ENV python=3.9
+    # Create symbolic link
+    ln -s /home/nvme/$USER/.envs/$MY_ENV ~/miniconda3/envs/$MY_ENV
+    # Activate environment
+    conda activate $MY_ENV
+    ```
