Don't even read this if you haven't got README.md right

## Things to setup

If you want to make some contribution to the project, please take some minute setting things up.

Editing file  that are bind-mounted over a container is not totally trivial; if you use vim, please
`set modeline backupcopy` in your vimrc. This will make your editing a bit more pleasant and avoid [known
issues](https://github.com/moby/moby/issues/15793). If you don't use vim, check that your editor doesn't
change inode to editing file, or editing files live from host to container will give you headache.

Please also see [GIT.md](GIT.md) for tips on setting git.

## Coding, running, coding

The instructions in README.md are fine when you only want to run. However, when developing, you might need to
know some more tricks.

The goal of our build manager (`dodo.py`) is to make a single call to `doit`, without arguments, always a sane
and correct choice. However that could not always be the case.

Let's organize our explanation into "iterations": you are typically developing on some aspect of it, and
not on the entire setup. Based on this, you'll need to do different things.

### Loops

#### Hacking code on tt-rss or rss-bridge

If you are changing PHP code, well, this is the easiest part.
Run `doit`, and you should have everything running, and logs showing up.
Then, with your favourite editor, edit the PHP files you prefer. You can then refresh what you want in the
browser, and everything should be automatically changing. No other action required!

#### Changing nginx configuration

Currently, there is no way to reload nginx, even though it should not be impossible, theoretically, to do it.
So edit `docker/nginx.conf` with your favourite editor then run `doit`. On the next change, give `ctrl-c` to
`doit` and then again run `doit`.

This workflow could be improved, being currently a bit too slow for such an easy thing.

#### Change some docker file

When you change the dockerfile you need to build everything again. Doit should notice this, and just running
`doit` should build everything again. If for some reason this is not the case, `doit clean build` will clean
all of our artifacts; so that running `doit` will surely rebuild everything.

Notice that building is a bit slow. There is no way to improve this, so just keep it in mind!
