+# Fully scripted installation
+
+In some cases even Jsonnet evaluation may not be enough to fully support complex installation decision making.
+
+To replace the regular installation process, use the
+`inst.script` [boot option](../boot_options). You can use any of the
+[URLs that Agama supports](../urls). It can be used repeatedly.
+
+It downloads a file, makes it executable and runs it. It is suggested to run these
+commands as part of the script:
+- `agama config load`
+- `agama install`
+
+If `inst.auto` is also present, it is processed after `inst.script`.
+
+:::warning Experimental feature
+
+With [`inst.auto`](working-with-profiles) we commit to backward compatibility, but
+with `inst.script`, as it is a last minute feature, we reserve the freedom to evolve
+Agama even in ways that may break this year's `inst.script` programs.
+
+We plan to specify this feature better and stabilize it by SP1, the first service pack.

+For scripts more limited in scope, specified as part of the JSON profile, see [Running scripts](profile/scripts).
