+# Python Libraries
+
+Endless Lifecycle Support (ELS) for Runtimes & Libraries from TuxCare provides security fixes for a variety of Python Libraries. This allows you to continue running your Python applications without vulnerability concerns, even after official support has ended.
+
+## Supported Python Libraries
+
+* **certifi:** 2021.10.8, 2022.12.7, 2023.7.22
+
+*Other libraries upon request.
+
+## Connection to ELS for Python Libraries Repository
+
+This guide outlines the steps needed to integrate the TuxCare ELS for Python Libraries repository.
+
+### Step 1: Get user credentials
+
+You need a username and password in order to use TuxCare ELS for Python Libraries repository. Anonymous access is disabled. To receive the credentials please contact [[email protected]](mailto:[email protected]).
+
+### Step 2: Set Up ELS for Python Libraries
+
+To use TuxCare's ELS for Python libraries, follow one of the options below:
+
+#### Option 1: Install a Package with ELS Repository via Command Line
+
+You can install or upgrade a package directly using the ELS repository with your credentials:
+
+<CodeWithCopy>
+
+```text
+pip install --upgrade \
+  -i https://<username>:<password>@nexus-repo.corp.cloudlinux.com/repository/els-python/simple \
+  <package>
+```
+
+</CodeWithCopy>
+
+**Replace:**
+* `<username>` and `<password>` - with the credentials provided by sales.  
+* `<package>` - with the Python package name (e.g., `certifi`).
+
+#### Option 2: Configure `pip` to Use the ELS Repository (Full Replacement)
+
+This method is recommended if you want to use only ELS-patched Python packages from TuxCare and replace the default PyPI source with the TuxCare ELS repository. 
+
+1. Create or update the `pip` configuration file and add the following:
+
+   <CodeTabs :tabs="[
+   { title: 'Linux/macOS (~/.pip/pip.conf)', content:
+   `[global]
+   index-url = https://username:[email protected]/repository/els-python/simple` },
+   { title: 'Windows (%APPDATA%\pip\pip.ini)', content:
+   `[global]
+   index-url = https://username:[email protected]/repository/els-python/simple` }
+   ]" />
+
+2. Run the command to install the latest package version:
+
+   <CodeWithCopy>
+
+   ```text
+   pip install --upgrade <package>
+   ```
+
+   </CodeWithCopy>
+
+   **Replace `<package>` with the python package name, for example, certifi.**
+
+   Or install a specific patched TuxCare version, for example:
+
+   <CodeWithCopy>
+
+   ```text
+   pip install certifi==2021.10.8.post2+tuxcare
+   ```
+
+   </CodeWithCopy>
+
+#### Option 3: Add the TuxCare ELS Repository as Additional (recommended )
+
+If you want to keep using public PyPI and fetch only specific patched packages from TuxCare, use *extra-index-url* instead. In this configuration, make sure to specify the exact patched version (step 2 below), otherwise `pip` may install the version from public PyPI.
+
+1. Create or update the `pip` configuration file and add the following:
+
+   <CodeTabs :tabs="[
+   { title: 'Linux/macOS (~/.pip/pip.conf)', content:
+   `[global]
+   extra-index-url = https://username:[email protected]/repository/els-python/simple` },
+   { title: 'Windows (%APPDATA%\pip\pip.ini)', content:
+   `[global]
+   extra-index-url = https://username:[email protected]/repository/els-python/simple` }
+   ]" />
+
+2. Run the command to install a specific patched TuxCare version, for example:
+
+   <CodeWithCopy>
+
+   ```text
+   pip install certifi==2021.10.8.post2+tuxcare
+   ```
+
+   </CodeWithCopy>
