When ran on the host, the `./ynh-dev` command allows you to manage YunoHost's dev LXCs.
First, you might want to build the base LXC with:
Start your actual dev LXC using :
```bash
$ cd ynh-dev # if not already done
$ ./ynh-dev rebuild
# ... This will take some time, grab your favorite beverage ...
```
This should create a fresh Debian Stretch LXC, install Yunohost inside and save
the result as `ynh-dev-base` which can then be used to create your actual dev
LXC. (This base can then be used to recreate a fresh Yunohost LXC if you need to
destroy your work LXC)

Then start your actual dev LXC using :

$ ./ynh-dev start

This should automatically download from `devbaseimgs.yunohost.org` a pre-build ynh-dev LXC image running Yunohost unstable, and create a fresh container from it.
After starting the LXC, your terminal will automatically be attached to it. If you later disconnect from the LXC, you can go back in with `./ynh-dev attach`. Later, you might want to destroy the LXC. You can do so with `./ynh-dev destroy`.
