 ## Development
 
-Generally you should have `Docker` or something alike installed.
-
 If you need to copy files into the container, don't forget to add exclusions to the general _exclude all_ in `.dockerignore`.
 
-To **update the base image** (like `3.12.4-alpine3.20` to a newer Alpine version), manual work is still required, but supported by a little script. **Renovate might not create a PR for newer image tags.**
-
-1. In the `Dockerfile`, update the Alpine version for the image and the renovate comments (`# renovate: datasource=repology depName=alpine_3_20/gcc versioning=loose`).
-
-   ```diff
-   - FROM python:3-alpine3.19@sha256:00c0ffeeacab...
-   + FROM python:3-alpine3.20 # You can omit the sha256 digest, the script prints it out
-   # ...
-
-   - # renovate: datasource=repology depName=alpine_3_19/build-base versioning=loose
-   + # renovate: datasource=repology depName=alpine_3_20/build-base versioning=loose
-   ENV BUILD_BASE_VERSION="0.8.15"
-   # ...
-   ```
-
-1. Now run `./get_pkg_versions.sh`. It pulls the alpine image from the Dockerfile, prints it's digest and the latest packages it could find via `apk` inside that container and prints out the names and versions.
-
-   Example output of `./get_pkg_versions.sh` for a new image, which is not yet pulled:
-
-   ```plain

-1. Copy the package versions and update the respective `ENV` with it manually in the `Dockerfile`. You also might add the digest to the base image.
