Hi,

Just install on a fresh install FreeBSD-11.1-p9 iocage.

When I launch iocage without /dev/fd (fdescfs) it took almost 30 sec (visual chrono) to get the help message

[root@filer]# time iocage > /dev/null
real    0m24.993s
user    0m8.856s
sys     0m16.138s
[root@filer]# 

But if I mount the /dev/fd

[root@filer]# time iocage > /dev/null
real    0m0.401s
user    0m

Loving this project.

I feel like this project would benefit from a short quick start tutorial that demonstrate common methods such as:

Create item

    mutation = Operation(schema.Mutation)  # note 'schema.'
    mutation.create_item(input=dict(id="23432")).__fields__()

List items with filter

    op = Operation(schema.Query)  # note 'schema.'
    op.list_it

We get the return annotation for free, so we should allow users to do something with it.
