+# Leaflet Plugin Authoring Guide
+
+One of the greatest things about Leaflet is its powerful plugin ecosystem.
+The [Leaflet plugins page](http://leafletjs.com/plugins.html) lists dozens of awesome plugins, and more are being added every week.
+
+This guide lists a number of best practices for publishing a Leaflet plugin that meets the quality standards of Leaflet itself.

+
+## Presentation
+
+### Repository
+
+The best place to put your Leaflet plugin to is a separate [GitHub](http://github.com) repository.
+If you create a collection of plugins for different uses,
+don't put them in one repo —
+it's usually easier to work with small, self-contained plugins in individual repositories.
+
+### Name
+
+Most existing plugins follow the convention of naming plugins (and repos) like this: `Leaflet.MyPluginName`.
+You can use other forms (e.g. "leaflet-my-plugin-name"),
+just make sure to include the word "Leaflet" in the name so that it's obvious that it's a Leaflet plugin.
+
+### Demo
+
+The most essential thing to do when publishing a plugin is to include a demo that showcases what the plugin does —
+it's usually the first thing people will look for.
+
+The easiest way to put up a demo is using [GitHub Pages](http://pages.github.com/).
+A good [starting point](https://help.github.com/articles/creating-project-pages-manually) is creating a `gh-pages` branch in your repo and adding an `index.html` page to it  —
+after pushing, it'll be published as `http://<user>.github.io/<repo>`.
+
+### Readme
+
+The next thing you need to have is a descriptive `README.md` in the root of the repo (or a link to a website with a similar content).
+At a minimum it should contain the following items:
+
+- name of the plugin
+- a simple, concise description of what it does
+- requirements
+	- Leaflet version
+	- other external dependencies (if any)
+	- browser / device compatibility
+- links to demos
+- instructions for including the plugin
+- simple usage code example
+- API reference (methods, options, events)
+
+### License
+
+Every open source repository should include a license.
+If you don't know what open source license to choose for your code,
+[MIT License](http://opensource.org/licenses/MIT) and [BSD 2-Clause License](http://opensource.org/licenses/BSD-2-Clause) are both good choices.
+You can either put it in the repo as a `LICENSE` file or just link to the license from the Readme.
+
+## Code
+
+### File Structure
+
+Keep the file structure clean and simple,
+don't pile up lots of files in one place  &mdash;
+make it easy for a new person to find their way in your repo.
+
+A barebones repo for a simple plugin would look like this:
+
+```
+my-plugin.js
+README.md
+```
+
+An example of a more sophisticated plugin file structure:
+
+```
+/src        - JS source files
+/dist       - minified plugin JS, CSS, images
+/spec       - test files
+/lib        - any external libraries/plugins if necessary
+/examples   - HTML examples of plugin usage
+README.md
+LICENSE
+package.json
+```
+
+### Code Conventions
+
+Everyone's tastes are different, but it's important to be consistent with whatever conventions you choose for your plugin.
+
+For a good starting point, check out [Airbnb JavaScript Guide](https://github.com/airbnb/javascript).
+Leaflet follows pretty much the same conventions
+except for using smart tabs (hard tabs for indentation, spaces for alignment)
+and putting a space after the `function` keyword.
+
+### Plugin API
+
+Never expose global variables in your plugin.<br>
+If you have a new class, put it directly in the `L` namespace (`L.MyPlugin`).<br>
+If you inherit one of the existing classes, make it a sub-property (`L.TileLayer.Banana`).<br>
+If you want to add new methods to existing Leaflet classes, you can do it like this: `L.Marker.include({myPlugin: …})`.
+
+Function, method and property names should be in `camelCase`.<br>
+Class names should be in `CapitalizedCamelCase`.
+
+If you have a lot of arguments in your function, consider accepting an options object instead
+(putting default values where possible so that users don't need specify all of them):
+
+```js
+// bad
+marker.myPlugin('bla', 'foo', null, {}, 5, 0);
+
+ // good
+marker.myPlugin('bla', {
+	optionOne: 'foo',
+	optionThree: 5
+});
+```
+
+And most importantly, keep it simple. Leaflet is all about *simplicity*.

+
+Leaflet is an open source JavaScript library for **mobile-friendly interactive maps**.
+It is developed by [Vladimir Agafonkin][] of [MapBox][] with a team of dedicated [contributors][].
+Weighing just about 30 KB of gzipped JS code, it has all the [features][] most developers ever need for online maps.
+
+Leaflet is designed with *simplicity*, *performance* and *usability* in mind.
+It works efficiently across all major desktop and mobile platforms out of the box,
+taking advantage of HTML5 and CSS3 on modern browsers while being accessible on older ones too.
+It can be extended with a huge amount of [plugins][],
+has a beautiful, easy to use and [well-documented][] API
+and a simple, readable [source code][] that is a joy to [contribute][] to.
+
+For more info, docs and tutorials, check out the [official website][].<br>
+For **Leaflet downloads** (including the built master version), check out the [download page][].
+
+We're happy to meet new contributors.
+If you want to **get involved** with Leaflet development, check out the [contribution guide][contribute].
+Let's make the best mapping library that will ever exist,
+and push the limits of what's possible with online maps!
