## Scope of the document

This document collects Open Source MANO User Guide.

## Guidelines for contributors

* OSM [Workflow for documentation production](https://osm.etsi.org/gitlab/osm-doc/documentation-how-to/blob/master/Workflow%20for%20documentation%20production%20in%20OSM.md#guide-for-contributors) must be used.

* Every section of this document, under a "H1" tag (single #), must be contained in a single file and formatted according to the following [sample document](#)

## Exporting the document to HTML

This markdown format can be easily exported by installing and using [Sphinx](http://www.sphinx-doc.org/en/master/) in your local machine.

Install the required packages:

```bash

sudo -H python3 -m pip install -r requirements.txt

```

Then run:

```bash

make html

```

The generated HTML output is stored in `_build/html`. You can go to that folder and publish the content locally with a Simple HTTP Server in Python.

```bash

python3 -m http.server <PORT>

```

Then you can check the generated HTML output with a local web browser pointing to <http://localhost:PORT>
