 If you want to manually install Calibre-Web (“from source”), follow the procedure below.
 
-1. Make sure you have installed pip and also venv for your python version. If missing, install it by the package manager of your distribution (e.g., apt for debian like distributions)
+1. **Ensure you have pip, venv, and cryptography installed**.  
+   - Install `pip`, `venv`, and `cryptography` for your Python version using your package manager (e.g., apt for Debian-based distributions).
+     - `sudo apt install python3-pip python3-venv python3-cryptography`
+   - Alternatively, you can install the `cryptography` package inside the virtual environment for a more up-to-date version:
+     - `./venv/bin/python3 -m pip install cryptography`
 
-    - `sudo apt install python3-pip python3-venv`
+2. **Go to the folder where you want to install Calibre-Web**, e.g.,
+    - `cd /opt/calibre-web`
 
-2. Go to the folder where you want to install Calibre-Web, e.g., 
-    -  `cd /opt/calibre-web`

-3. Create virtual environment for calibre web in the current folder
+3. **Create a virtual environment** for Calibre-Web in the current folder:
     - `python3 -m venv venv`
 
-4. Download and extract Calibre-Web into the current folder (in this example /opt/calibre-web) from the releases page on Github
+4. **Download and extract Calibre-Web** into the current folder (in this example, `/opt/calibre-web`) from the [releases page on Github](https://github.com/janeczku/calibre-web/releases).
 
-5. Install dependencies by running 
+5. **Install dependencies** by running:
     - `./venv/bin/python3 -m pip install -r requirements.txt`
 
-6. Execute the command: 
-    - `./venv/bin/python3 cps.py` (or `nohup ./venv/bin/python3 cps.py` - recommended if you want to exit the terminal window)
+6. **Execute Calibre-Web** with the command:
+    - `./venv/bin/python3 cps.py`  
+    (or use `nohup ./venv/bin/python3 cps.py` if you want to exit the terminal window)
 
-Issues on Raspberry Pi Raspberry Pi OS:
-Depending on your version of pip it's possible that the installation fails with `Failed to build cryptography
-ERROR: Could not build wheels for cryptography, which is required to install pyproject.toml-based projects`. In this case please try to update pip with `./venv/bin/python3 -m pip install --upgrade pip` first, and then try installing Calibre-Web again. If this isn't working please also install cargo via `sudo apt install cargo`, and try again to install Calibre-Web.
+#### Additional Issues and Considerations:
 
-Issues with Ubuntu:
-Please note that running the above install command can fail on some versions of Ubuntu, saying `"can't combine user with prefix"`. This is a [known bug](https://github.com/pypa/pip/issues/3826) and can be remedied by using the command `./venv/bin/python3 -m pip install --system -r requirements.txt` instead.
+**Raspberry Pi (Raspberry Pi OS)**:  
+Depending on your version of pip, the installation might fail with `Failed to build cryptography`. If you encounter this issue, try:
+1. Updating pip:  
+    - `./venv/bin/python3 -m pip install --upgrade pip`
+2. If the error persists, install `cargo`:  
+    - `sudo apt install cargo`
+3. Then, try installing Calibre-Web again.
 
-Remark: All config files (settings database, log files) are stored in Calibre-Web root folder (in this example /opt/calibre-web). Additional config files, such as the config files for gdrive and gmail have to be placed there too.
+**Ubuntu**:  
+On some Ubuntu versions, you may see the error `can't combine user with prefix`. This is a [known bug](https://github.com/pypa/pip/issues/3826) and can be resolved by installing the requirements with the `--system` flag:
+   - `./venv/bin/python3 -m pip install --system -r requirements.txt`
 
-#### Manual installation on Windows
+**Configuration Files**:  
+All configuration files (settings database, log files) are stored in the Calibre-Web root folder (in this example, `/opt/calibre-web`). Any additional config files, such as those for Google Drive or Gmail integration, should be placed there as well.
 
-For Windows pip and venv come with the basic installation. On Windows, the python binary can be found after installing the virtual environment under .\venv\script\python3.exe.

-1. Download and install the newest python version for windows from here: [https://www.python.org/downloads/windows/](https://www.python.org/downloads/windows/)
+### Manual Installation on Windows
 
-2. Start an command prompt via "cmd". Go to the folder where you want to install Calibre-Web, e.g., `c:\calibre-web `
+On Windows, pip and venv are included with the basic Python installation. Follow the steps below:
 
-3. Create virtual environment for calibre web in folder venv. The python installation in the example is c:\python

+
+2. **Open a command prompt (cmd)** and navigate to the folder where you want to install Calibre-Web, e.g., `c:\calibre-web`.
+
+3. **Create a virtual environment** for Calibre-Web in the folder `venv`:
     - `c:\python\python.exe -m venv venv`  
+      (This example assumes Python is installed in `c:\python`.)
