 # Apt pinning the Percona Server for MySQL {{vers}} packages
 
-Pinning allows you to stay on a release and get packages from a different version. In some cases, you can pin selected packages and avoid accidentally upgrading all the packages. 
+Apt pinning helps you control which version of a package is installed from different repositories. This is useful when you want to stay on a specific release such as Percona Server for MySQL 8.4 and avoid automatic upgrades from other sources.
 
-The pinning takes place in the `preference` file. To pin a package, set the `Pin-Priority` to higher numbers. 
- 
-Make a new file `/etc/apt/preferences.d/00percona.pref`. For example, add the following to the `preference` file:
+To pin the Percona Server for MySQL 8.4 packages, follow these steps:
+{.power-number}
 
-```text
-Package: 
-Pin: release o=Percona Development Team
-Pin-Priority: 1001
-```
+1.  Create a preferences file in `/etc/apt/preferences.d/` named `00percona.pref`:
 
-For more information about the pinning, you can check the official [debian wiki](https://wiki.debian.org/AptConfiguration?action=show&redirect=AptPreferences).
+    ```{.bash data-prompt="$"}
+    $ sudo nano /etc/apt/preferences.d/00percona.pref
+    ```
+
+2.  Add the pinning configuration content to the file:
+
+    ```ini
+    Package: percona-server-server
+    Pin: release o=Percona Development Team,a=stable
+    Pin-Priority: 1001
+    ```
+
+    * The `Package` field specifies the exact name of the package.
+    * The `Pin` field identifies the origin of the package, which is the Percona repository.
+    * The `Pin-Priority` field sets the priority level. A value above 1000 ensures this version is preferred over others.
+
+    Save and close the file.
+
+3.  Update package lists to refresh your package sources:
+
+    ```{.bash data-prompt="$"}
+    $ sudo apt update
+    ```
+
+4.  Install Percona Server for MySQL 8.4 using the following command:
+
+    ```{.bash data-prompt="$"}
+    $ sudo apt install percona-server-server
+    ```
+
+    Your system prioritizes the version from the Percona repository according to your pinning settings.
