Anybody can host a screening, and the terms are on this page.

Everybody signed — Before filming, in plain language, with the form read aloud to anybody who preferred that. A signature nobody understood is not consent
They saw it before anybody else — The whole film, not their own bits. Screened privately, with time afterwards to say something
They could withdraw — Up to the point where the film was locked, which was a date they were all told in advance rather than one chosen afterwards
Two people did — And they are not in it. That is written here because a page claiming nobody ever withdraws is a page nobody should believe
Nobody was paid — For taking part. Travel and childcare were covered, and that distinction is worth stating rather than blurring
Children — A parent's consent and the child's own, and the child's could be withdrawn at any point up to release without the parent's agreement

What is in it — Replace this with the specifics for your own film, and put roughly where in the running time each one falls
Roughly when — By minute. "Contains distressing scenes" tells nobody when to look away; "around minute forty" does
What is not shown — Just as useful, and almost never stated. If the worst of it happens off camera, say so — it changes who can watch
At a screening — There is a door, it is at the back, and nobody will notice you use it. Say that out loud at the start of every screening
Watching it alone — Is harder than watching it in a room. That is true of most films like this and it is worth knowing beforehand
Afterwards — The discussion guide has a section for anybody who found it difficult, and it is the first section rather than an appendix

It isn't an investigation — It follows people. If you want the reporting, it exists and it is linked below rather than summarised badly here
It doesn't name everybody — Some things could not be verified to a standard worth publishing, so they aren't in it. That is a choice, not an oversight
It doesn't tell you what to think — There is no narration doing that job. Several people who disagree with each other are all in it and none is set up to lose
It isn't the whole story — Seventy-eight minutes out of two years. What was cut is on the record if anybody asks, and people do
It won't fix anything by itself — Films don't. What they do is get a room of people into the same conversation, which is why the screening terms are this generous
Where to go next — The organisations doing the actual work are listed in the guide, and none of them paid to be there

What you actually need — A screen, a speaker loud enough for the back row, and one person to say a sentence at the start
What gets sent — A file that plays offline, two poster sizes, a discussion guide, and captions in the languages we have
If nobody comes — Eleven people is a good turnout for a first screening and it is enough. Do not measure this against a cinema
If money is taken — Keep it, unless you booked the ticketed licence, in which case the smaller of the two figures is owed and it is trusted rather than audited
