+
+Ensure your migrations are linear.
+
+Requirements
+============
+
+Python 3.5 to 3.9 supported.
+
+Django 2.2 to 3.1 supported.
+
+----
+
+**Are your tests slow?**
+Check out my book `Speed Up Your Django Tests <https://gumroad.com/l/suydt>`__ which covers loads of best practices so you can write faster, more accurate tests.
+
+----
+
+Installation
+============
+
+First, install with **pip**:
+
+.. code-block:: bash
+
+    python -m pip install django-migration-conflicts
+
+Second, add the app to your ``INSTALLED_APPS`` setting:
+
+.. code-block:: python
+
+    INSTALLED_APPS = [
+        ...
+        "django_migration_conflicts",
+        ...
+    ]
+
+The app relies on overriding the built-in ``makemigrations`` command.
+If your project has a custom ``makemigrations`` command, ensure the app containing your custom command is **above** ``django_migration_conflicts``, and that your command subclasses its ``Command`` class:
+
+.. code-block:: python
+
+    # myapp/management/commands/makemigrations.py
+    from django_migration_conflicts.management.commands.makemigrations import (
+        Command as BaseCommand,
+    )
+
+
+    class Command(BaseCommand):
+        ...
+
+Third, run this one-off command for installation:
+
+.. code-block:: sh
+
+    python manage.py makemigrations --create-max-migration-files
+
+This extra subcommand creates a new ``max_migration.txt`` file in each of your apps’ ``migrations`` directories and exits.
+More on that file below...
+
+Usage
+=====
+
+django-migration-conflicts helps you work on Django projects where several branches adding migrations may be in progress at any time.
+It enforces the use of a *linear* migration history, avoiding merge migrations and any possible problems from migrations running in different orders.
+It does this by turning parallel migration development into conflicts on per-app ``max_migration.txt`` files that your source control tool (Git, Mercurial, etc.) will detect.
+
+Its extended ``makemigrations`` command updates the ``max_migration.txt`` file with the name of the new migration when run.
+
+System Checks
+=============
+
+django-migration-conflicts comes with several system checks that verify that your ``max_migration.txt`` files are in sync.
+These are:
+
+* ``dmc.E001``: ``<app_label>``'s max_migration.txt does not exist.
+* ``dmc.E002``: ``<app_label>``'s max_migration.txt contains multiple lines.
+* ``dmc.E003``: ``<app_label>``'s max_migration.txt points to non-existent migration '``<bad_migration_name>``'.
+* ``dmc.E004``: ``<app_label>``'s max_migration.txt contains '``<max_migration_name>``', but the latest migration is '``<real_max_migration_name>``'.
+
+Limitations
+===========
+
+This only works with ``.py`` migration files.
+
+Inspiration
+===========
+
+I've seen versions of this technique implemented at my previous client `Pollen <https://pollen.co/>`__ and in `this Doordash blogpost <https://medium.com/@DoorDash/tips-for-building-high-quality-django-apps-at-scale-a5a25917b2b5>`__, and have ended up implementing it myself a couple of times.
+There's also `django-migrations-git-conflicts <https://pypi.org/project/django-migrations-git-conflicts/>`__ which does similar.
