+   **PRO TIPS**:
    - On **Ubuntu** and **Debian**, `python3-cryptography` is installed by default, unlike on Raspberry Pi OS.
    - Installing `python3-cryptography` is not required if you plan to install a newer version using pip as described in Step 4.
 
 2. **Download and extract Calibre-Web:**
+    - `sudo mkdir -p /opt`
     - `cd /opt`
-    - `git clone https://github.com/janeczku/calibre-web`
+    - `sudo git clone https://github.com/janeczku/calibre-web`
     - `cd calibre-web`
 
 3. **Create a virtual environment** for Calibre-Web:
-    - `python3 -m venv venv`
+    - `sudo python3 -m venv venv`
 
 4. **Install dependencies** by running:
-    - `./venv/bin/python3 -m pip install -r requirements.txt`
+    - `sudo ./venv/bin/python3 -m pip install -r requirements.txt`
 
     **PRO TIP:**
     - **If you want a more recent version of `cryptography`** than your OS offers:
-      - `./venv/bin/python3 -m pip install cryptography`
+      - `sudo ./venv/bin/python3 -m pip install cryptography`
 
 5. **Run Calibre-Web** with the command:
-    - `./venv/bin/python3 cps.py`
+    - `sudo ./venv/bin/python3 cps.py`
 
     **PRO TIP:**
     - Or use `nohup ./venv/bin/python3 cps.py` if you want to exit the terminal window.
