 The included certificate is generated through the _dotnet dev-certs_ command. This is a very convenient and suitable way to generate development certificates through the dotnet SDK.
 
 The password used to generate the certificate is randomly generated through the `openssl rand -base64 12` at build time.
-If you inspect the image layers you'll able to easily see it.
-I think this is fine for development purposes and just want to get things up and running, although this is not recommended for production use at all.
-You can generate your own password and certificates in the following way :
-
-```sh
-# generate a random secure password
-openssl rand -base64 12
-# use the .net cli to generate your own certificates with your chosen password
-dotnet dev-certs https --export-path /config/aspnetapp.pem --password "YOUR PASSWORD" --format PEM
-```
-After this you only need to map your own certificates with the **ASPNETCORE_Kestrel__Certificates__** variables.
-
-### Versioning
-
-Recently Microsoft decided to update the base images to alpine 3.22.
-Before 2025-11-11 the latest supported version was alpine 3.21.
-In order to support these changes the naming scheme will need to be changed.
-Going forward specefic tags will be vailable for the different versions: by example `9.0.11-alpine-21` and `9.0.11-alpine-22`.
-By default alpine 22 will be used and the older versions will be supported as long Microsoft does.
+The build agent used for the build is hosted on my own infrastructure but I don't have any access to it (neither do I intend to do so).<br/>
+However if you feel uncomfortable with this fact, feel free to build the image yourself.
