+This module extends the functionality of any model to support multiple images
+(a gallery) attached to it and allow you to manage them.

+
+Installation
+============
+
+This module adds abstract models to work on. Its sole purpose is to serve as
+base for other modules that implement galleries, so if you install this one
+manually you will notice no change. You should install any other module based
+on this one and this will get installed automatically.
+
+Configuration
+=============
+
+To manage all stored images, you need to:
+
+* Go to *Settings > Technical > Multi images*.
+
+... but you probably prefer to manage them from the forms supplied by
+submodules that inherit this behavior.
+
+Development
+===========
+
+To develop a module based on this one:
+
+* See module ``product_multi_image`` as an example.
+
+* You have to inherit model ``base_multi_image.owner`` to the model that needs
+  the gallery::
+
+    class MyOwner(models.Model):
+        _name = "my.model.name"
+        _inherit = ["my.model.name", "base_multi_image.owner"]
+
+        # If you need this, you will need ``pre_init_hook_for_submodules`` and
+          ``uninstall_hook_for_submodules`` as detailed below.
+        old_image_field = fields.Binary(related="image_main", store=False)
+
+* Somewhere in the owner view, add::
+
+    <field
+        name="image_ids"
+        nolabel="1"
+        context="{
+            'default_owner_model': 'my.model.name',
+            'default_owner_id': id,
+        }"
+        mode="kanban"/>
+
+* If the model you are extending already had an image field, and you want to
+  trick Odoo to make those images to multi-image mode, you will need to make
+  use of the provided `~.hooks.pre_init_hook_for_submodules` and
+  `~.hooks.uninstall_hook_for_submodules`, like the
+  ``product_multi_image`` module does::
+
+    try:
+        from odoo.addons.base_multi_image.hooks import (
+            pre_init_hook_for_submodules,
+            uninstall_hook_for_submodules,
+        )
+    except ImportError:
+        pass
+
+
+    def pre_init_hook(cr):
+        """Transform single into multi images."""
+        pre_init_hook_for_submodules(cr, "product.template", "image")
+        pre_init_hook_for_submodules(cr, "product.product", "image_variant")
+
+
+    def uninstall_hook(cr, registry):
+        """Remove multi images for models that no longer use them."""
+        uninstall_hook_for_submodules(cr, registry, "product.template")
+        uninstall_hook_for_submodules(cr, registry, "product.product")

+
+Known issues / Roadmap
+======================
+
+* *OS file* storage mode for images is meant to provide a path where Odoo has
+  read access and the image is already found, **not for making the module store
+  images there**. It would be nice to add that feature though.
+
+Bug Tracker
+===========
+
+Bugs are tracked on `GitHub Issues <https://github.com/OCA/server-tools/issues>`_.
+In case of trouble, please check there if your issue has already been reported.
+If you spotted it first, help us smashing it by providing a detailed and welcomed
+`feedback <https://github.com/OCA/server-tools/issues/new?body=module:%20base_multi_image%0Aversion:%2014.0%0A%0A**Steps%20to%20reproduce**%0A-%20...%0A%0A**Current%20behavior**%0A%0A**Expected%20behavior**>`_.
