# m.room.join_rules

Controls who can join the room. This is best to configure in room settings.

## knocking

Requires room version 7

```json
{
	"join_rule": "knock"
}
```

## membership of another room

Requires room version <del>8</del> 9. Offers only Spaces in room settings

```json
{
	"allow": [
		{
			"room_id": "!whatever:example.net",
			"type": "m.room_membership"
		}
	],
	"join_rule": "restricted"
}
```

It can be assumed that multiple spaces is simply copying that more,
see below (with exception of `join_rule`)

### merging knocking and membership of another room

Practically the same, but requires room version 10 and new `join_rule` known as
`knock_restricted`

```json
{
	"allow": [
		{
			"room_id": "!ddFNqIRUacwdicInJz:feneas.org",
			"type": "m.room_membership"
		},
		{
			"room_id": "!fGtopoZuCySnTsSdsU:matrix.org",
