+Extends ``project_task_code`` to let each project use its own task code
+sequence. Tasks with no project, or with a project that has no sequence
+set, keep using the global sequence.
+
+**Table of contents**
+
+.. contents::
+   :local:
+
+Configuration
+=============
+
+1. Create a sequence at Settings > Technical > Sequences & Identifiers >
+   Sequences (developer mode).
+2. Open the project, go to the **Settings** tab and pick it in the
+   **Task Sequence** field.
+
+Usage
+=====
+
+New tasks in a project with a sequence get their code from it. Otherwise
+the global task sequence is used.
+
