First, clone & enter the repo directory:
git clone git@github.com:questdb/documentation.git
cd documentationNext, install dependencies:
yarn
yarn start
This command starts a local development server and open up a browser window.
Most changes are reflected live without having to restart the server.
You'll need to sign a quick CLA.
Pretty standard, check it out.
This is done on PR creation.
First create a new branch.
Locally, ensure your changes look good.
Then push your branch to GitHub and create a PR.
We'll review the PR and generate a preview build.
A QuestDB member must add the preview label to your PR to deploy a preview build.
Once it looks good, we'll merge!
We'd love your help!

Our SQL syntax diagrams are created using Railroad.
To create a diagram, use the Railroad online editor to see it rendered.
Once you're happy with it, copy the Railroad syntax and add it to:
static/images/docs/diagrams/.railroad
Ensure it fits the full pattern - there are many examples:
renameTable
::= 'RENAME' 'TABLE' oldName 'TO' newName
Be sure to maintain proper indentation!
Next, run the scripts/railroad.py [name] script to generate the SVG image.
For example:
python3 scripts/railroad.py renameTableDuring its final output, a markdown image with the appropriate syntax is printed:
Copy the image syntax below and paste it into your markdown file:
Copy this syntax and paste it into the markdown file where you want the diagram to appear.
The script requires:
- Java (to run the
rr.warfile) - Python (to execute the
railroad.pyscript)
Use LaTeX-style math between $ for inline or $$ for block equations:
$$
text
Inline equation: $f(x) = x^2$
Block equation:
$$
\int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi}
$$
Create diagrams using Mermaid syntax in code blocks:
graph TD
A[Start] --> B{Is it?}
B -- Yes --> C[OK]
C --> D[Rethink]
D --> B
B -- No --> E[End]
Syntax highlighting for many languages, including QuestDB SQL:
questdb-sql
SELECT
FROM trades
WHERE timestamp > dateadd('d', -1, now())
SAMPLE BY 1h;
