+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at [jekyll@sverrirs.com](mailto:jekyll@sverrirs.com). All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+# WebP Generator for Jekyll (Extended)
+WebP Image Generator for Jekyll Sites can automatically generate WebP images for all images on your static site and serve them when possible. View on [rubygems.org](https://rubygems.org/gems/jekyll-webp).
+
+**This repo is an extended version of it's fork [jekyll-webp](https://github.com/sverrirs/jekyll-webp)**
+
+## Additional Features
+- Generate thumbnails in webp format
+- Generate small images (.5x) in webp format
+- Specifiy output sub directory for webp images
+
+## Additional Dependencies
+- fastimage
+
+## Installation instructions
+```
+group :jekyll_plugins do
+ gem 'jekyll-webp', git: 'https://github.com/Rohithzr/jekyll-webp-ext', branch: 'extend'
+end
+```
+
+## Original installation instructions
+
+```
+gem install jekyll-webp
+```
+
+The release includes all necessary files to run, including the WebP redistributable executable files.
+
+> Currently the release includes the v0.6.1 version of the WebP utilities for Windows, Linux and Mac OS X 10.9 (Mountain Lion). Other versions and releases can be downloaded directly from the Google page.
+
+Add the gem to your `Gemfile` and to Jekyll's `_config.yml` then run `jekyll serve` again and you should see the generator run during site generation.
+
+## Configuration
+The plugin can be configured in the site's `_config.yml` file by including the `webp` configuration element
+
+``` yml
+############################################################
+# Site configuration for the WebP Generator Plugin
+# The values here represent the defaults if nothing is set
+webp:
+ enabled: true
+
+ # The quality of the webp conversion 0 to 100 (where 100 is least lossy)
+ quality: 75
+
+ # List of directories containing images to optimize, nested directories will only be checked if `nested` is true
+ # By default the generator will search for a folder called `/img` under the site root and process all jpg, png and tiff image files found there.
+ img_dir: ["/img"]
+
+ # Whether to search in nested directories or not
+ nested: false
+
+ # add ".gif" to the format list to generate webp for animated gifs as well
+ formats: [".jpeg", ".jpg", ".png", ".tiff"]
+
+ # File extensions for animated gif files
+ gifs: [".gif"]
+
+ # Set to true to always regenerate existing webp files
+ regenerate: false
+
+ # Local path to the WebP utilities to use (relative or absolute)
+ # Omit or leave as nil to use the utilities shipped with the gem, override only to use your local install
+ # Eg : "/usr/local/bin/cwebp"
+ webp_path: nil
+
+ # List of files or directories to exclude
+ # e.g. custom or hand generated webp conversion files
+ exclude: []
+
+ # append '.webp' to filename after original extension rather than replacing it.
+ # Default transforms `image.png` to `image.webp`, while changing to true transforms `image.png` to `image.png.webp`
+ append_ext: false
+
+ ##### Extended Features start
+ # Use a different output subdirectory
+ # e.g. value of "/optimized" will create files at "/source/optimized" instead of "/source"
+ output_img_sub_dir: "/optimized" # default ""
+
+ # Generate thumbnails
+ thumbs: true
+
+ # Thumbnails sub directory
+ thumbs_dir: "/thumbs"
+
+ # generate .5x images
+ generate_50p: true
+
+ ##### Extended Features end
+############################################################
+```
+
+## Simplest use: HTML
+In case you don't have control over your webserver then using the `` element and specifying all image formats available is the best option. This way the browser will decide which format to use based on its own capabilities.
+
+``` html
+
+
+
+
+```
+
+## Advanced use: Webserver Configuration
+If you can, then configuring your webserver to serve your new _.webp_ files to clients that support the format is probably the least problematic approach. This way you don't need to make any changes to your HTML files as your webserver will automatically serve WebP images when the client supports them.
+
+Below is an example for a .htaccess configuration section in an Apache web-server. It will redirect users to webp images whenever possible.
+
+```
+####################
+# Attempt to redirect images to WebP if one exists
+# and the client supports the file format
+####################
+# check if browser accepts webp
+RewriteCond %{HTTP_ACCEPT} image/webp
+
+# check if file is jpg or png
+RewriteCond %{REQUEST_FILENAME} (.*)\.(jpe?g|png)$
+
+# check if corresponding webp file exists image.png -> image.webp
+RewriteCond %1\.webp -f
+
+# serve up webp instead
+RewriteRule (.+)\.(jpe?g|png)$ $1.webp [T=image/webp,E=accept:1]
+
+AddType image/webp .webp
+```
+
+> Depending on other configurations in your `.htaccess` file you might have to update your `ExpiresByType`, `ExpiresDefault` and `Header set Cache-Control` directives to include the webp format as well.
