+These are the documentation sources for the powsybl-open-loadflow features.
+
+Please keep them up to date with your developments.  
+They are published on [powsybl-open-loadflow.readthedocs.io](http://powsybl-open-loadflow.readthedocs.io/) and pull requests are built and previewed automatically.
+
+When modifying the website content, you can easily preview the result on your PC.
+
+**First option - in a terminal, navigate to the root of the project and run the following commands:**
+
+~~~
+pip install -r docs/requirements.txt
+sphinx-build -a docs ./build-docs
+~~~
+
+*Note: if the build fails, try with the `-E` option to clear the cache:*
+
+~~~
+sphinx-build -a -E docs ./build-docs
+~~~
+
+**Second option - run the following commands directly from your IDE GUI**
+
+~~~bash
+pip install -r requirements.txt
+~~~
+
+~~~bash
+sphinx-build -a . ../build-docs
+~~~
+
+**Preview the result**
+
+Then open `build-docs/index.html` in your browser.
+
+If you want to add links to another documentation, add the corresponding repository to the `conf.py` file.
+In order to automatically get the version specified in the `pom.xml`, please use the same naming as the version: if you define the
+powsybl-core version with `<powsyblcore.version>`, then use `powsyblcore` as key. The specified URL should start with `https://` and end with `latest/` (the final `/` is mandatory).
+For example, to add a link to the documentation of PowSyBl-Core, you need to add the following lines:
+~~~python
+# This parameter might already be present, just add the new value
+intersphinx_mapping = {
+    "powsyblcore": ("https://powsybl-core.readthedocs.io/en/latest/", None),
+}
+~~~
+
+Then in your documentation file, you can add links to PowSyBl-Core documentation. If you want to link to a whole page,
+use one of the following example:
+~~~Markdown
+- [load flow configuration](inv:powsyblcore:*:*#simulation/loadflow/configuration).
+~~~
+
+If you want to link a specific part of a page, use one of those examples:
+~~~Markdown
+- [load detail extension](inv:powsyblcore:*:*:#load-detail-extension).
+~~~
+*Note: for the last examples to work, there need to be a corresponding reference in the external documentation.
+For those examples, `(load-detail-extension)=` has been added right before the corresponding title
+in the powsybl-core documentation.
+
+*Note²: if the build fails, try with the `-E` option to clear the cache:*
+~~~bash
+sphinx-build -a -E docs ./build-docs
+~~~
+
