+debputy - Integration modes
+===========================
+
+_This is [reference documentation] and is primarily useful if you want to know more on integration modes_
+_If you want to migrate to one of these integration modes, then [GETTING-STARTED-WITH-dh-debputy.md](GETTING-STARTED-WITH-dh-debputy.md) might be better._

+
+
+The debputy tool is a Debian package builder, and it has multiple levels of
+"integration" with the package build. Each integration mode has different
+pros and cons, which will be covered in this document.
+
+The integration modes are:
+
+ * `dh-sequence-zz-debputy-rrr`
+ * `dh-sequence-zz-debputy` (or `dh-sequence-debputy`)
+ * `full`
+
+The integration modes that start with `dh-sequence-` are named such because
+they leverage `dh` and its add-on system. The `dh-sequence-zz-` is a trick
+to convince `dh` to load the add-ons last when they are activated via
+`Build-Depends`, which is part of `debputy`'s strategy for maximizing
+compatibility with other `dh` add-ons.
+
+Integration mode - `dh-sequence-zz-debputy-rrr`
+-----------------------------------------------
+
+This integration mode is a minimal integration mode aimed exactly at removing the
+(implicit) requirement for `fakeroot` in packages that need static ownership in
+the `.deb`.
+
+It trades many of `debputy` features for compatibility with `debhelper` and ease
+of transitions.
+
+This integration mode is relevant for you when:
+
+ * You want to get rid of the implicit `fakeroot` requirement, and you need static
+   ownership, OR
+ * You want to transition to `debputy` in the long term, but more involved integration
+   modes do not support what you need, OR
+ * The mode has a particular feature you want that `debhelper` does not provide.
+
+
+Pros:
+
+ * You can use `debputy` to assign static ownerships without needing `fakeroot`,
+   which is not possible with `debhelper`.
+ * You get maximum compatibility with existing `dh` add-ons.
+ * Migration is generally possible with minimal or small changes.
+ * It is accessible in `bullseye-backports`
+
+Cons:
+
+ * Many of `debputy`'s features cannot be used.
+ * Most limitations of `debhelper` still applies (though these limitations are the
+   status quo, so the package would have a solution to them if needed).
+ * You still longer a turning complete configuration language for your package helper
+   (`debian/rules`) with poor introspection.
+
+To migrate, please use:
+
+     debputy migrate-from-dh --migration-target dh-sequence-zz-debputy-rrr
+
+Note: The `debputy migrate-from-dh` command accepts a `--no-act --acceptable-migration-issues=ALL`,
+if you want to see how involved the migration will be.
+
+For documentation, please see:
+ * [GETTING-STARTED-WITH-dh-debputy.md] for a more detailed migration guide (how-to guide).
+ * https://wiki.debian.org/BuildingWithoutFakeroot
+
+
+Integration mode - `dh-sequence-zz-debputy`
+-------------------------------------------
+
+This integration mode is a more involved integration mode of `debputy` that partly leverages
+`dh`. In this mode, `debputy` will take over all the logic of installing files into the
+respective package staging directories (`debian/<pkg>`). Roughly speaking, the original
+`debhelper` runs until `dh_auto_install` and then `debputy` takes over.
+
+This integration mode is relevant when:
+
+ * You want to migrate to the `full` integration mode, but you would like to split the migration
+   in two, OR
+ * You want to use more of `debputy`'s features and do not use any unsupported `dh` add-ons without
+   wanting to migrate the build part.
+
+Pros:
+
+ * You can use the most features of `debputy`. Only the build and environment related ones are
+   not accessible.
+ * It is accessible in `bullseye-backports`
+
+Cons:
+
+ * Almost all `dh` add-ons will stop working since they rely on being able to see the content
+   of `debian/<pkg>`. Since `debputy` will populate *and* assemble the `.deb`, there is never
+   a window for the affected add-on to work. Any features provided by these add-ons would have
+   to be provided by a `debputy` plugin (or `debputy` itself).
+ * Your only `debhelper` limitations is `dh` notorious lack of proper multi-build support.
+ * You still longer a turning complete configuration language for your package helper
+   (`debian/rules`) with poor introspection.
+
+To migrate, please use:
+
+     debputy migrate-from-dh --migration-target dh-sequence-zz-debputy
+
+Note: The `debputy migrate-from-dh` command accepts a `--no-act --acceptable-migration-issues=ALL`,
+if you want to see how involved the migration will be. It will also detect possible incompatible
+`dh` add-ons if you are concerned about whether your package can be supported.
+
+For documentation, please see:
+ * [GETTING-STARTED-WITH-dh-debputy.md] for a more detailed migration guide (how-to guide).
+
+
+Integration mode - `full`
+-------------------------
+
+This is the integration mode that `debputy` is about. In the `full` integration mode, `debputy`
+replaces `dh` as the package helper. It even removes `debian/rules` replacing it with `dpkg`'s
+new `Build-Driver` feature.
+
+Pros:
+
+ * You can use all features from `debputy` including its native multi-build support.
+ * You can still leverage `debhelper` build systems (anything integrating with the `dh_auto_*`
+   tools.) via the `debhelper` build system.
+ * You no longer have a turning complete configuration language for your package helper
+   (`debian/rules`) with poor introspection.
+
+Cons:
+
+ * (Temporary) Incomplete `debputy migrate-from-dh` support
+ * It is a new ecosystem missing a lot of the third-party features you would find for `dh`.
+   Only `debhelper` build systems (`dh_auto_*`) can be reused.
+ * It requires Debian `trixie` or later due to `Build-Driver` (`dpkg-dev`)
+ * You no longer have the flexibility of a turning complete configuration language for your
+   package helper, which some people might miss. :)
+
+To migrate, please use:
+
+     debputy migrate-from-dh --migration-target full
+
+Note: The `debputy migrate-from-dh` command accepts a `--no-act --acceptable-migration-issues=ALL`,
+if you want to see how involved the migration will be. It will also detect possible incompatible
+`dh` add-ons if you are concerned about whether your package can be supported.
