 # Génévée
 
-A merovingian king/queen name generator.
+A merovingian king/queen name generator. Beyond its (let's face it, limited)
+intrinsic usefulness, this project is primarily meant to demonstrate a web
+front-end development workflow using [SJW](https://git.marvid.fr/Tissevert/SJW)
+and [guix](https://guix.gnu.org/).
 
-## Deploy with [SJW](https://git.marvid.fr/Tissevert/SJW)
+## Dependences
 
+The following instructions hence assumes that you already have `guix`
+installed. Regarding `SJW`, it is available from the
+[loom](https://git.marvid.fr/Tissevert/loom) guix channel. Depending on how you
+chose to make it available, the following lines could be slightly different but
+to avoid luring you with some irrealistic simplicity, we will assume in what
+follows that you have cloned the `loom` channel in a sibling folder from this
+repository, so that its root is located at `../loom` relatively to this
+repository. The syntax will be lighter if you add the `loom` to your known guix
+channels.
+
+## Build from a local clone of this repository (hacking)
+
+The Génévée website can be built with this line:
+
+```sh
+$ guix shell -L ../loom -D -f guix.scm -- make
 ```
-# sjw src -o main.js
+
+This is of course a one liner, but if you're actually working on an improvement
+you'll probably want to spawn a development environment with:
+
+```sh
+$ guix shell -L ../loom -D -f guix.scm
 ```
+
+You improve the code in your favourite text editor, and from time to time
+when you want to see your changes applied you simply recompile the site with
+`make` in the previously-spawned shell environment:
+
+```sh
+[env]$ make
+```
+
+which will create or refresh `main.js`.
+
+Alternatively if your editor handles compilation, calling `make` from some
+button or shortcut, you probably just want to run it from an enriched
+environment containing it plus the requirements for this package:
+
+```sh
+$ guix shell -L ../loom -D -f guix.scm emacs -- emacs
+```
+
+Simply opening the `index.html` from your browser lets you see your changes and
+work on them. On more complex projects requiring a back-end, you'll want to add
+a web server to your own environment and point it to your working copy. You can
+of course draw inspiration from the [deployment](#deploy) section below, but
+respawning a VM each time you edit a line is by no means practical so even if
+your development server lives in a container or virtual machine, you'll be
+better off directly writing to the source files it hosts as long as your
+tweaking the code.
+
+## Prepare for distribution (checking)
+
+You're becoming satisfied with your improvement and are seriously considering
+to submit a patch. You commit all your changes and build this site as any
+regular `guix` package the usual way:
+
+```sh
+$ guix build -L ../loom -f guix.scm
+```
+
+The site's files are directly at the root of the directory which path is
+displayed by the previous command right before it returns (your hash will be
+different and that's ok):
+
+```sh
+…
+/gnu/store/f2w493gg7cn94dgbx8dyg2fr0srxm8qa-genevee-0.1.0
+$ ls /gnu/store/f2w493gg7cn94dgbx8dyg2fr0srxm8qa-genevee-0.1.0
+index.html  main.js  scribish.ttf  style.css
+```
+
+Building the site this way helps you make sure that you haven't forgotten any
+implicit dependency, for instance if you have introduced a new `SJW` library in
+the code and forgot to add it in Génévée's [`native-input`
+field](https://guix.gnu.org/fr/manual/devel/en/html_node/package-Reference.html)
+in `guix.scm`.
+
+If the content of this directory works as expected and is up to your standards,
+on to pushing the commit or sending a patch. Otherwise edit, `commit --amend`,
+rinse and repeat.
+
+## Deploy !
+
+Maybe you're used to seeing usual UNIX programs built with `guix` and you
+expect the content of a `/gnu/store` package's root to look like a profile with
+the usual `bin/`, `etc/`, `share/`, etc. directories. The cool thing with the
+above structure is that the package becomes directly useful as a kind of
+symbolic reference to a given state of the site's source.
+
+### To a guix system
+
+Suppose you want to host it on a `guix` server. All you have to do is add a web
+server service to its configuration, nginx for the sake of the example, and
+point a location to the `genevee` package itself:
+
+```guile
+(define genevee (load "guix.scm"))
+```
+…
+```guile
+(service nginx-service-type
+ (nginx-configuration
+  (server-blocks
+   (list (nginx-server-configuration
+          (root genevee))))))
+```
+
+In fact, have you noticed the `genevee-in-a-vm.scm` in this repository ? This
+few lines are actually enough to let you spin a local demo of a server hosting
+Génévée in virtually (ahah) no time.
+
+```sh
+$ `guix system vm -L ../loom genevee-in-a-vm.scm` -nic user,model=virtio-net-pci,hostfwd=tcp::8000-:80
+```
+
+Once the VM is up, visit [http://localhost:8000](http://localhost:8000) to
+admire your local instance of Génévée.
+
+### Anywhere else
+
+The target server where you want to deploy Génévée is the last remaining part
+of your fleet not (yet) running `guix` ? That's too bad but don't worry, you
+can still benefit from this structure and use the cool script `deploy.sh`
+(included). Assuming you SSH into your host at `my.vps.net`, and you want to
+put Génévée into, say, `/srv/httpd/Génévée/` — where you have write access —
+simply call:
+
+```sh
+./deploy.sh my.vps.net:/srv/httpd/Génévée
+```
+
+Of course this just calls `rsync` with the path expanded from the evaluation of
+`guix build` like above. Adapt to taste when you use a different protocol to
+sync into production.
