### Create a kiwi-config instance

Any directory is implicitly a valid kiwi-scp instance using the default configuration.
To prevent surprises however, you should run `kiwi init` in an empty directory and follow its directions to
create a `kiwi.yml` before using `kiwi` more.
### Concept
A `kiwi-config` instance is a directory containing a bunch of static configuration files.
A kiwi-scp instance is a directory containing a bunch of static configuration files.
"Static" there as in "those don't change during normal service operation".
These files could be anything from actual `.conf` files to entire html-web-roots.
Non-static, but persistent files are to be kept in a "service data directory", by default `/var/kiwi`.
In your `docker-compose.yml` files, you can refer to that directory as **${TARGETROOT}**.
Start the current directory as a `kiwi-config` instance using `kiwi up`, or stop it using `kiwi down`.
Start the current directory as a kiwi-scp instance using `kiwi up`, or stop it using `kiwi down`.
This also creates kiwi's internal hub network, which you can use as **kiwi_hub** in your `docker-compose.yml` files.
### Projects
A `kiwi-config` instance usually contains several projects.
A kiwi-scp instance usually contains several projects.
A project is a collection of dependent or at least logically connected services, described by a `docker-compose.yml`.

For this use case, create a directory named `conf` in a project.

#### For everything else, look at `kiwi --help`
#### Happy admin-ing!
#### `kiwi.yml` options
##### `version`
Version of kiwi-scp to use for this instance.
Default: Latest version.
##### `runtime:storage`
Path of the service data directory, available as **${TARGETROOT}** in projects.
Default: `/var/kiwi`
##### `runtime:shells`
List of additionally preferable shell executables when entering service containers.
Default: `- /bin/bash`
Example:
```yaml
runtime:
shells:
- /bin/zsh
- /bin/fish

##### `runtime:env`
Associative array of custom variables available in projects' `docker-compose.yml` files.
Default: `null`
Example:
```yaml
runtime:
env:
HELLO: "World"
FOO: "Bar"
