-Building
---------
-
-`Graphviz <https://graphviz.org/>` is needed to compile the documentation.
-
-Also the following Python dependencies:
-
-``pip install 'sphinx<7.3' sphinx_rtd_theme sphinx-prompt sphinxcontrib-spelling pyyaml sphinx-substitution-extensions``.
-
-Build the documentation by running ``make html``.
-[More information](http://sphinx-doc.org/).
-
-Spell checking
--------------
-
-`sphinxcontrib.spelling <https://sphinxcontrib-spelling.readthedocs.io/en/latest/index.html` is needed to run the spell checker.
-
-Also, the following Python dependencies:
-``pip install sphinxcontrib-spelling pyenchant``
-
-And the `python3-enchant package`:
-``sudo apt install python3-enchant``
-
-If the spellchecker job fails for your branch, you can check the job log which will display the file + word that didn't pass the spell checker along with some suggestions.
-Either you will have to correct the typo and push it again, or if it's a false positive, you can update the custom wordlist used at `source/ext/spellchecking/wordlists/opennebula.txt`
