 **Orchestra Cities** is a data and IoT-driven solution that allows cities to
 collaboratively develop and share Smart City Services using Open APIs and
 Open Standards. Launched in 2018 by [Martel Innovate](https://www.martel-innovate.com),
 Orchestra Cities was initially developed and tested with Antwerp and Helsinki

-## Documentation
 
-This repository hosts the main documentation of Orchestra Cities.
+### Repository content
+
+This repository hosts the source and build tools for Orchestra Cities'
+documentation site.
+
+The documentation consists of an introduction, where the most important
+topics and ideas are briefly explained, and a tutorial, where the user
+can get some hands-on experience of the most important platform features.
+
+The documentation site source is in the `docs` folder and it gets fed
+into MkDocs to build a static site. Nix provides reproducible, sand-boxed
+and cross-platform development environments.
+
+
+### Development environment
+
+We use Nix to get proper, isolated and reproducible development
+environments. This is a sort of virtual shell environment on steroids
+which has in it all the tools you need with the right versions. Plus,
+it doesn't pollute your machine with libraries that could break your
+existing programs—everything gets installed in an isolated Nix store
+directory and made available only in the Nix shell.
+
+First off, you should install Nix and enable the Flakes extension
+
+```bash
+$ sh <(curl -L https://nixos.org/nix/install) --daemon
+$ mkdir -p ~/.config/nix
+$ echo 'experimental-features = nix-command flakes' >> ~/.config/nix/nix.conf
+```
+
+Now you can get into our Nix shell and use the tools you need to
+develop: Bash, git, MkDocs, etc.
+
+```bash
+$ cd nix
+$ nix shell
+```
+
+
+### Editing content
+
+The documentation site source is in the `docs` folder. Write in plain
+markdown. Use figures accordingly. Put images and binary resources
+in `docs/rsrc`. Respect the naming schema of the files in there to
+keep it reasonably organised.
+
+You can build the documentation site and live edit it easily with
+the `mkdocs` command. After getting into the Nix shell as explained
+earlier, go back to the repository's root directory and run
+
+```bash
+$ mkdocs build
+```
+
+This will output the whole static site in the `site` directory—there's
+a `.gitignore` file to keep this directory out of source control. To
+see what the site looks like, run

-### Organisation

+`docs` directory, your changes should be reflected in the browser.

+### Deploying the site

-### Usage
+```bash

+$ nix build .#docs-site
+```
 
-1. Run `sh run.sh`
-1. Open `http://127.0.0.1:8000/` in your explorer and you should see the docs
