## Writing Documentation
|
|
|
|
Documentation pages are generated from the Markdown files in `contents/`. The files are organized in 4 sections/folders (getting-started, properties, examples, contributing) which are dynamically listed on the docs overview page. The Markdown files can have some header files containing metadata.
|
|
|
|
```markdown
|
|
---
|
|
path: "docs/flexDirection"
|
|
title: "Flex Direction"
|
|
hasPlayground: true
|
|
initialPlayground: eyJ3aWR0aCI6IjYwMCIsImhlaWdodCI6NTAwLCJjaGlsZHJlbiI6W3t9LHt9LHt9XX0=

The `path` can be any URL this page should be available at. The `title` is used as the page's HTML-title and when referencing the file from the documentation overview. There are two kinds of templates for a page: with and without playground. `hasPlayground` selects the corresponding template (`src/templates/{with|without}Playground.js`). With `hasPlayground: true`, one can add a flex control which can be placed inline with the text in markdown. For example you can do the following,
|
|
|
|
```markdown
|
|
## Align Content
|
|
|
|
The property defines the distribution of lines along the cross-axis. This only
|
|
has effect when items are wrapped to multiple lines (see [flexWrap](flex-wrap)).
|
|
|
|
<controls prop="alignContent"></controls>
|
|
|
|
```
|
|
|
|
There is one more metadata property called `initialPlayground` which allows to provide the custom playground for the documentation. For getting the playground id, create custom yoga layout in [playground](/playground) and copy the string after # from playground URL. For example if playground URL looks like this `https://yogalayout.com/playground#<PLAYGROUND_ID>`, then playground id is the string after `#`. If it isn't the one like in the previous format then actually its default playground, so one can skip this field.
