# Page format > How requests, suggestions and comments are stored inside a plain markdown file. A page is one markdown file. Everything Solipsist adds is an HTML comment, so any markdown tool can still read it. When Sync writes back to your original, it leaves Solipsist's comments out. ## Markers A request is a **marker** in the text: an HTML comment with its kind (`gen`, `sel`, `img`), its id and its state. ```md A point where a completion was asked for: The deadline is the end of the month for all teams. ``` *[Picture: A range marker in the editor: the words underlined, with a turning ring beside them]* The same range marker as the editor shows it. - A **point** marks a place. A **range** opens and closes around the text it's about. - If a request has an instruction, your words are kept on the opening comment. - The state comes after the id: nothing while it's waiting, `ack` while an agent works on it, `sug` when a suggestion is waiting for you, `done`, and `btn` for a result kept as a [button](https://solipsist.sh/docs/guides/buttons/). An HTML comment you wrote yourself is kept exactly as you wrote it and shown as a chip. ## The hidden block One comment at the end of the file holds everything that isn't in the text: the page's agent settings, a record for each request (its kind, state, times, the agent and model that worked on it, its suggestion, and the text the agent saw), and the margin comments from a page review. ```md ``` The block's `format` says which builds can write it. If a page is in a newer format than the build you're running, it opens read-only with its agents off, so the older build can't write it wrong. Keys a build doesn't recognise are left as they are.
