# Contributing
This repository welcomes contributions and corrections. Before submitting a pull request, ensure that you respect these guidelines for SVGs:
- Include the SVG namespace declaration `xmlns="http://www.w3.org/2000/svg"`. This is not required if the SVG is included inline on HTML5 web pages.
- Include a descriptive `
` element for accessibility. The `` must have an ID of the format `simpleicon--title` - for example, `GitHub icon `.
- Add `aria-labelledby="simpleicon--title"` and `role="img"` to the `` element to improve screen reader support.
- Use a `viewBox` of 24 by 24, following [Google’s Material Design guidelines for system icons](https://material.io/guidelines/style/icons.html#icons-system-icons).
- Ensure the icon is scaled to fit the viewbox, while preserving the icon's original propportions. This means the icon should be touching _at least_ two sides of the viewbox.
- Ensure the icon is horizontally and vertically centered.
- Ensure that all paths and strokes have been converted to fills.
- Ensure your SVG is monochromatic. Remove all fill colors so that icons default to black.
- Minify your SVG after exporting it. We recommend using [SVGO](https://github.com/svg/svgo) or [SVGOMG](https://jakearchibald.github.io/svgomg/) to automate this process. **Do not go below a precision of 3**.
## JSON data for simpleicons.org
In addition to following the guidelines for SVGs, list new icons in the `_data/simple-icons.json` file. Each icon in the array has three required values:
- The `title` of the new SVG.
- A `hex` color value that matches the brand or logo's main accent color. (Without the `#` pound symbol.)
- The `source` URL of the logo being used.
Here is the object for the GitHub logo as an example:
```json
{
"title": "GitHub",
"hex": "181717",
"source": "https://github.com/logos"
},
```
## SVG example
Before minification, your SVG should look follow the template below:
```svg
[BRAND] icon
```
While the parent `` element can sometimes contain other attributes, the attributes listed above are the only necessary ones. You can safely remove attributes like `width` and `height`, or clean them using a tool like [SVGO](https://github.com/svg/svgo) or [SVGOMG](https://jakearchibald.github.io/svgomg/).
Here is the un-minified contents of the GitHub icon, for reference:
```svg
GitHub icon
```
