 Icon Repository for [Nativefier](https://github.com/nativefier/nativefier/).
 
-Nativefier will look in this repository for high resolution icons before trying to automatically infer an icon from the target Url.
-
-The [index](https://nativefier.github.io/nativefier-icons/) is automatically generated with [GitCloud](https://github.com/jiahaog/gitcloud) using Jekyll.
-
-## Contributing
-
-Feel free to submit a pull request for any `.ico`, `.icns` or `.png` icon!
-
-- `.ico` - For Windows
-- `.icns` - For macOS (Apple Icon Image format)
-- `.png` - For Linux
-
-If the icons for the correct platforms are found here, the [optional dependencies](https://github.com/nativefier/nativefier/#optional-dependencies) for Nativefier might not be required to infer an icon for that particular target web page.
-
-### Naming Convention
-
-Name the icon file to `${PRODUCT}.${EXT}`, just use the key identifier for the page.
-
-However, if the product name is generic enough, name it as `${COMPANY}-${PRODUCT}.${EXT}`, with `-` as the delimiter. The matching algorithm works by taking a score of the number of words matched in the file name with the target url. 
-
-Take the example of naming Google Photos for the target url `https://photos.google.com/`. Using `photos.png` is too generic, and we want it to be specific to google. Thus, we will name the icon file `google-photos.png` for a `.png` file. 
-
-### Step 1
-
-First prepare the image files, for the respective platform as stated above
-
-A helpful tool for converting the icons is [iconverticons.com](https://iconverticons.com/online/).
-
-Copy the images to `./files`.
-
-```
-$ ls -a ./files
-
-google-photos.png
-google-photos.ico
-google-photos.icns
-```
-
-### Step 2
-
-Add an entry for the file to `./_data/gitCloud.yml`, in alphabetical order
-
-```yml
-- name: google-photos
-  href: files/google-photos.png
-- name: google-photos
-  href: files/google-photos.ico
-- name: google-photos
-  href: files/google-photos.icns
-```
-
-### Step 3
-
-You're done! Submit a pull request with the changes and I'll merge them in as soon as possible.
-
-## Helper Scripts
-
-The main [`./addIcon`](addIcon) script is also provided which takes an input `.png` or `.svg` and does steps 1 and 2 automatically for you.
- 
-This script only runs on OSX with XCode installed as [iconutil](https://developer.apple.com/library/mac/documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Optimizing/Optimizing.html) is required for conversion to a `.icns` file.
-
-Other helpful scripts are:
-
-- [`./bin/convertToIcns`](bin/convertToIcns) 
-- [`./bin/convertToIco`](bin/convertToIco) (Supported on Linux)
-- [`./bin/convertToPng`](bin/convertToPng) (Supported on Linux)
-
-You need the following dependencies:
-
-- [ImageMagick](http://www.imagemagick.org/script/index.php) with `convert` and `identify` in your `$PATH` (required for `.png` input)
-- [CairoSVG](https://cairosvg.org) (required for `.svg` input)
-- [iconutil](https://developer.apple.com/library/mac/documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Optimizing/Optimizing.html): Xcode needs to be installed (required to generate `.icns`)
-
-## Work In Progress
-
-- [ ] CI tests for pull requests
-- [ ] Just use a `.png` or `.svg` and let CI convert the icons to the other formats
