+This document describe the migration from DevContainer to the new mkdocs structure (with poetry) made by Jacques Supcik.
+
+First version of this document: 22.08.2023/BUN
+
+# Migration Steps
+
+1. Delete the ```.devcontainer``` directory
+2. On the console, type 
+   ```bash
+   poetry config virtualenvs.in-project true
+   poetry init
+   poetry add mkdocs mkdocs-material
+   poetry run mkdocs new .
+   ```
+3. Modify the ```pyproject.toml``` with the correct Python version (on OSX):
+   ```yaml
+   [tool.poetry.dependencies]
+   #python = "^3.11"
+   python = ">=3.11,<3.12"
+   ```
+
+4. Add some mkdocs plugins:
+   ```bash
+   poetry add mkdocs_include_markdown_plugin
+   poetry add mkdocs-awesome-pages-plugin
+   poetry add mkdocs-macros-plugin
+   poetry add mkdocs-pages-j2-plugin
+   poetry add python-markdown-math
+   poetry add mkdocs-git-revision-date-localized-plugin
+   poetry add mkdocs-calendar-plugin
+   poetry add mkdocs-jconfig-plugin
+   poetry add mkdocs-glightbox
+   ```
+
+   ou sur moins de lignes:
+   ```bash
+   poetry add mkdocs_include_markdown_plugin mkdocs-awesome-pages-plugin mkdocs-macros-plugin 
+   poetry add mkdocs-pages-j2-plugin python-markdown-math mkdocs-git-revision-date-localized-plugin
+   poetry add mkdocs-calendar-plugin mkdocs-jconfig-plugin mkdocs-glightbox
+   ```
+
+5. We can now start the server:
+   ```bash
+   poetry run mkdocs serve
+   ```
+
+6. We have now to modify the config files to get the correct theme and structure. The directory ```config``` is no more used. From the files in this directory:
+   * move ```mkdocs.yml``` to the root directory
+   * move the content of the ```base.yml``` at the beginning of the ```mkdocs.yml```
+   * comment or remove the lines:
+     ```md
+     # hooks:
+     #  - hooks.py
+     ```
+
+7. Add variables into the ```mkdocs.yml``` file, in the ```extra``` section, for example:
+   ```yaml
+     lecture_week: 16
+     lecture_show: 999
+     exo_show_data: 999
+     exo_show_solution: 999
+     lab_show_data: 999
+     lab_show_solution: 0
+     ```
+
+8. Add the following to the ```plugins``` section of the ```mkdocs.yml``` file (if misssing):
+   ```yaml
+      plugins:
+         ...
+          - pages-j2
+          - calendar:
+             tz: Europe/Zurich
+   ```
+
+9. Rename variables in your ```.md``` documents, if necessary:
+   * ```assignment_show_data``` --> ```lab_show_data```
+   * ```assignment_show_solution``` --> ```lab_show_solution```
+
+10. Some cleaning:
+   * delete the ```config``` directory
+
+
+10. Test the new configuration by starting your local server:
+    ```bash
+    poetry run mkdocs serve
+    ```
+
+11. Publish the site on gitlab with the new ```.gitlab-ci.yml``` content,
+    as describe on Jacques [documentation](https://heia-fr.github.io/mkdocs-edu-howto/publishing/)
