 ## Enable encryption
 
-Percona Distribution for PostgreSQL Docker image includes the `pg_tde` extension to provide data encryption. You must explicitly enable it when you start the container. For more information, see the [pg_tde documentation](https://docs.percona.com/pg-tde/index.html).
-
-Follow these steps to enable `pg_tde`:
-
-1. Start the container with the `ENABLE_PG_TDE=1` environment variable:
-
-    ```{.bash data-prompt="$"}
-    docker run --name container-name -e ENABLE_PG_TDE=1 -e POSTGRES_PASSWORD=sUpers3cRet  -d percona/percona-distribution-postgresql:{{dockertag}}
-    ```
-
-    where:
-
-    * `container-name` is the name you assign to your container
-    * `ENABLE_PG_TDE=1` adds the `pg_tde` to the `shared_preload_libraries` and enables the custom storage manager
-    * `POSTGRES_PASSWORD` is the superuser password
-
-2. Connect to the container and start the interactive `psql` session:
-
-    ```{.bash data-prompt="$"}
-    docker exec -it container-name psql
-    ```
-
-    ??? example "Sample output"
-
-        ```{.text .no-copy}
-        psql ({{dockertag}} - Percona Server for PostgreSQL {{dockertag}}.1)
-        Type "help" for help.
-
-        postgres=#
-        ```
-
-3. Create the extension in the database where you want to encrypt data. This requires superuser privileges.
-
-    ```sql
-    CREATE EXTENSION pg_tde;
-    ```
-
-4. Configure a key provider with a keyring file. This setup is intended for development and stores the keys unencrypted in the specified data file. The below sample configuration is intended for testing and development purposes.
-
-    !!! note
-         For production use, we **strongly recommend** setting up an external key management store and configure an external key provider. Refer to the [Setup :octicons-link-external-16:](https://docs.percona.com/pg-tde/setup.html#key-provider-configuration) topic in the `pg_tde` documentation.
-
-    <i warning>:material-information: Warning:</i> This example is for testing purposes only:
-
-	```sql
-	SELECT pg_tde_add_database_key_provider_file('file-vault', '/tmp/pg_tde_test_001_basic.per');
-    ```
-
-5. Set the principal key:
-
-    ```sql
-    SELECT pg_tde_set_key_using_database_key_provider('test-db-key', 'file-vault');
-    ```
-
-    The key is auto-generated. You are ready to use data encryption.
-
-6. Create a table with encryption enabled. Pass the `USING tde_heap` clause to the `CREATE TABLE` command:
-
-    ```sql
-    CREATE TABLE <table_name> (<field> <datatype>) USING tde_heap;
-    ```
