+## How to generate Python requirements file with hashes?
+
+To generate a Python requirements.txt file with hashes, which ensures that the same versions of packages are installed across different environments, you can use the `pip-compile` tool from the `pip-tools` package. Here's a step-by-step guide on how to achieve this:
+
+### Steps:
+
+1. **Install pip-tools:**
+   First install pip-tools to manage you requirements.txt and add hashes.
+   ``` bash
+   pip install pip-tools
+   ```
+
+2. **Create requirements.in file:**
+   Add your packages to a requirements.txt file. This file will be used as input to generate the final requirements.txt file with hashes.
+   In case you need to use exact version of a package you can specify it in this file.
+   Example requirements.in:
+   ``` in
+   mkdocs==1.6.1
+   pymdown-extensions==10.9
+   ```
+
+3. **Compile the requirements.txt with hashes:**
+   Use pip-compile with `--generate-hashes` flag to create a requirements.txt file includes secure hashes.
+   ``` bash
+   pip-compile --generate-hashes
+   ```
+
+!!! note
+
+    If you want to use custom names of input and output requirements file, specify them in command line like this:
+
+    ``` bash
+    pip-compile --output-file=custom-requirements.txt --generate-hashes custom-requirements.in
+    ```
+
+    - Without `--output-file`: It will always create requirements.txt file.
+    - With `--output-file`: It will specify any custom output file name.
+
+4. **Result:**
+   It will generate a requirements.txt (or custom-requirements.txt) file with hashes for each package, ensuring the integrity and security of the installed packages.
+   Example output in requirements.txt:
+   ``` txt
+   mkdocs==1.6.1 \
+       --hash=sha256:... \
+       --hash=sha256:...
+   ...
+   pymdown-extensions==10.9 \
+       --hash=sha256:... \
+       --hash=sha256:...
+   ...
+   ```
