Formatting text with markdown
Most boxes where you write more than a line accept markdown: a small set of plain-text marks that turn into formatting when the page renders. You type **sold out**, readers see sold out.
Every one of those boxes has a Preview button. Use it — it renders exactly what your readers will see.
Where it works
- Your event description
- Event updates
- Agenda sessions and speaker bios
- How to get there — parking, transit, and doorbell notes
- Payment instructions, when you collect money off Cloomba
- The description under a guest question
- Calendar newsletters
Titles, names, and comments are plain text — markdown marks typed there show up as the characters you typed.
The basics
**bold** *italic* ~~struck out~~
- a bullet
- another bullet
1. first
2. second
> a quoted line
Three dashes on a line of their own draw a divider across the page.
Headings
Start your headings at ##. A single # is reserved — Cloomba uses it to mark language sections in event descriptions.
## Schedule
### Morning
That still leaves five levels, more than any event page needs. On an event page every heading level renders at close to the same size anyway: headings are there to give your text structure and something to scan, not big type.
Line breaks
This is the one place Cloomba differs from markdown elsewhere: a single line break is a real line break. Type a schedule one line at a time and it stays that way.
18:00 — doors
18:30 — first talk
19:15 — break
Leave a blank line between blocks to start a new paragraph.
Links
[our venue](https://example.com/venue)
Links to other sites open in a new tab, so someone half-way through filling in your registration form does not lose their answers. A web address typed on its own becomes a link automatically.
Tables
Good for schedules, line-ups, and price tiers.
| Time | Session | Speaker |
| ----- | --------------- | ------- |
| 18:30 | Indexing basics | Jana |
| 19:15 | Query plans | Marek |
Keep the number of columns small — the same table has to fit on a phone.
Images

In your event description there is a shortcut: paste an image from the clipboard, or drag a file into the box, and it uploads and inserts itself. Images sit on their own line and fill the width of the text column.
What does not work
- HTML. Tags,
<iframe>embeds, and scripts are ignored rather than shown. That includes embedded video players — link to the video instead. - Footnotes and mathematical notation.
If it looks wrong
Open Preview. Almost every surprise is one of three things: a heading with no space after the ##, an emphasis mark opened and never closed, or HTML pasted in from another site and dropped.
