 # Introduction
+
 This project provides Docker images to periodically back up a PostgreSQL database to AWS S3, and to restore from the backup as needed.
 
 # Usage

+- Images are tagged by the major PostgreSQL version supported: `13`, `14`, `15`, `16` or `17`.
 - The `SCHEDULE` variable determines backup frequency. See go-cron schedules documentation [here](http://godoc.org/github.com/robfig/cron#hdr-Predefined_schedules). Omit to run the backup immediately and then exit.
 - If `PASSPHRASE` is provided, the backup will be encrypted using GPG.
 - Run `docker exec <container name> sh backup.sh` to trigger a backup ad-hoc.
 - If `BACKUP_KEEP_DAYS` is set, backups older than this many days will be deleted from S3.
 - Set `S3_ENDPOINT` if you're using a non-AWS S3-compatible storage provider.

 > [!CAUTION]
 > DATA LOSS! All database objects will be dropped and re-created.

 # Development
+
 ## Build the image locally
+
 `POSTGRES_VERSION` determines Postgres version.
+
 ```sh
 DOCKER_BUILDKIT=1 docker build --build-arg POSTGRES_VERSION=17 .
 ```
+
 ## Run a simple test environment with Docker Compose
+
 ```sh
 cp template.env .env
 # fill out your secrets/params in .env
 docker compose up -d
 ```
 
 # Acknowledgements
-This project is a fork and re-structuring of @schickling's [postgres-backup-s3](https://github.com/schickling/dockerfiles/tree/master/postgres-backup-s3) and [postgres-restore-s3](https://github.com/schickling/dockerfiles/tree/master/postgres-restore-s3).
-
-## Fork goals
-These changes would have been difficult or impossible merge into @schickling's repo or similarly-structured forks.
-  - dedicated repository
-  - automated builds
-  - support multiple PostgreSQL versions
-  - backup and restore with one image
-
-## Other changes and features
-  - some environment variables renamed or removed
-  - uses `pg_dump`'s `custom` format (see [docs](https://www.postgresql.org/docs/10/app-pgdump.html))
-  - drop and re-create all database objects on restore
-  - backup blobs and all schemas by default
-  - no Python 2 dependencies
-  - filter backups on S3 by database name
-  - support encrypted (password-protected) backups
-  - support for restoring from a specific backup by timestamp
-  - support for auto-removal of old backups

+This project is a fork of @eeshugerman's [postgres-backup-s3](https://github.com/eeshugerman/postgres-backup-s3) repository. Since the original project is no longer maintained, I decided to fork it and merge an important pull request ([#61](https://github.com/eeshugerman/postgres-backup-s3/pull/61)) to add support for PostgreSQL 17.
+
+The original repository itself is a fork and restructuring of @schickling's [postgres-backup-s3](https://github.com/schickling/dockerfiles/tree/master/postgres-backup-s3) and [postgres-restore-s3](https://github.com/schickling/dockerfiles/tree/master/postgres-restore-s3).
