-##### security concerns
-The [german wikipedia tells that there are some security concern with fetchmail](https://de.wikipedia.org/wiki/Fetchmail). If in the future a customer needs to functions of fetchmail, it could be better to write a docker container for [getmail](https://en.wikipedia.org/wiki/Getmail) instead because it should be more secure.
+## Setup
 
-##### workaround
-If you need to receive emails from another account this should help:
+### Fetchmail Issues
 
-- Redirect to your new email account
-- Export all data from your original account
-- Import all data from your original account to your new account
+Fetchmail might not work properly with large amounts of data. For more information, refer to this [issue](https://github.com/Mailu/Mailu/issues/1719). 
 
-### delete data
-To delete all volumes and data execute:
+#### Deactivating Fetchmail
+
+Before uninstalling Fetchmail, ensure to remove all fetched accounts from the administration panel.
+
+#### Fetchmail Security Concerns
+
+There are known security concerns with Fetchmail as stated in the [German Wikipedia](https://de.wikipedia.org/wiki/Fetchmail). If you require Fetchmail functions in the future, consider creating a Docker container for [Getmail](https://en.wikipedia.org/wiki/Getmail) as it is considered more secure.
+
+#### Fetchmail Workaround
+
+If you need to receive emails from another account, follow these steps:
+
+1. Redirect your emails to your new email account.
+2. Export all data from your original account.
+3. Import all data to your new account.
+
+### Data Deletion
+
+To delete all volumes and data, execute the following command with caution:
 
 ```bash
-  rm -vr /etc/mailu/; docker volume rm $(docker volume ls -q | grep mailu_)
+rm -vr /etc/mailu/; docker volume rm $(docker volume ls -q | grep mailu_)
 ```
-Be careful!
 
-### ports
-Keep in mind to change the conflicting ports manual.
-Execute
+### Port Management
+
+Check for any port conflicts and manually change the conflicting ports if necessary. Use the following command to verify:
 
 ```bash
-  netstat -tulpn
+netstat -tulpn
 ```
 
-to verify that there aren't port conflicts
+### Admin Account Creation
 
-### admin account
-
-Before you can use Mailu, you must create the primary administrator user account. This should be admin@{{hostname}}. Use the following command, changing PASSWORD to your liking:
+To use Mailu, create the primary administrator user account, `admin@{{hostname}}`, using the command below. Replace `PASSWORD` with your preferred password:
 
 ```bash
-  docker-compose -p mailu exec admin flask mailu admin {{admin}} {{hostname}} PASSWORD
+docker-compose -p mailu exec admin flask mailu admin {{admin}} {{hostname}} PASSWORD
 ```

-## hard cleanup
+This README details the steps to manage your Pixelfed instance running in a Docker container. This setup is part of the server_docker-pixelfed role within Kevin Veen-Birkenbach's computer-playbook located at [this GitHub repository](https://github.com/kevinveenbirkenbach/computer-playbook/tree/master/roles/server_docker-pixelfed). 
+
+## Accessing Services
+
+### Application Access
+To gain shell access to the application container, run the following command:
+```bash
+docker-compose exec -it application bash
+```
+
+### Database Access
+To access the MariaDB instance in the database container, run the following command:
+```bash
+docker-compose exec -it database mariadb -u pixelfed -p
+```
+
+## Instagram Import Cleanup
+
+If you have imported posts from Instagram, you can clean up the imported data and files as follows:
+
+### Database Cleanup
+Run these commands inside your MariaDB shell to remove import related data:
+```bash
+DELETE from import_posts WHERE 1;
+DELETE from import_jobs WHERE 1;
+DELETE from import_datas WHERE 1;
+DELETE from statuses where created_at < "2022-12-01 22:15:39";
+DELETE from media where deleted_at >= "2023-07-28 14:39:05";
+```
+
+### File System Cleanup
+Run these commands to remove the imported files and trigger the cleanup job:
+```bash
+docker-compose exec -u "www-data" application rm -rv "/var/www/storage/app/imports/1"
+docker-compose exec -u "www-data" application php artisan schedule:run
+```
+
+## Full Cleanup (Reset)
+
+For a hard reset, which will delete all data and stop all services, use the following commands:
 ```bash
 docker-compose down
 docker volume rm pixelfed_application_data pixelfed_database pixelfed_redis_data
 ```
 
-## update
+## Update Procedure
+
+To update your Pixelfed instance, navigate to the directory where your `docker-compose.yml` file is located and run these commands:
 ```bash 
 cd {{path_docker_compose_files}}pixelfed/ &&
