It's explained in the article. First quote:

> You want a covered pail partially filled with water to put used diapers in as soon as removed. If it contains soap or detergent, this helps in removing stains. Be sure the soap is well dissolved, to prevent lumps of soap from remaining in the diapers later. When you remove a soiled diaper, scrape the movement off into the toilet with a knife, or rinse it by holding it in the toilet while you flush it (hold tight).

> You wash the diapers with mild soap or mild detergent in [the] washing machine or washtub (dissolve the soap well first), and rinse 2 or 3 or 4 times. The number of rinsings depends on how soon the water gets clear and on how delicate the baby’s skin is. If your baby’s skin isn’t sensitive, 2 rinsings may be enough.

The technique hasn't changed much.

We had a lidded bucket, dump any solids into the toilet, fold any remaining mess inside, put in bucket. We primed the bucket with water into which we put tea-tree oil (for scent and disinfectant purposes). Some people will use the toilet as a pre-rinse; never did it myself.

We used nappy liners, a piece of paper to catch the worst of the poo. And 'wraps' on the outside. The nappies had poppers; you could popper them differently as they grew.

On wash day, empty the water from the bucket into the toilet, lift the nappies individually into the [front-loading] washing machine.

We bought our cloth nappies on eBay, already second-hand. We passed them on still usable years afterwards.

I did start potty training as soon as they went on solids, well before they could sit unaided! We used baby-sign, and I tried a couple of elimination communication techniques. Baby-sign was great, they could tell us they needed potty before they could talk; first child even made a new toilet sign to differentiate between wee/poo.

We had compostable nappies for times when we needed them - too rainy to dry clothes, too sleepy, backup for when they wee/poo on the nappy as you're putting it on them when you're out and about.

Only thing we'd wash with the nappies was soiled clothing (baby grows) or towels we'd lie on the bed to change their nappy on. A month or so in we got a changing table (Ikea).

If there is poop on them you need to scrape it off.

We bought a pack of thin disposable diaper liners. These go inside the diaper and catch most of the business. They then get thrown away (but it’s much less waste/garbage than an entire diaper)

They do get their own load. The ones we have tell you to run them in the wash twice.
