 1 | # How to contribute
 2 | 
 3 | I'm delighted that you're helping make this open source project better. Here are a few quick guidelines to make this an easier and better process for everyone.
 4 | 
 5 | ## Reporting a bug
 6 | 
 7 | First, **make sure the bug hasn't already been reported** by searching GitHub's issues section.
 8 | 
 9 | If no existing issue exists, go ahead and create one. **Please be sure to include all of the following:**
10 | 
11 | 1. A clear, descriptive title (ie. "A bug" is *not* a good title).
12 | 2. [A reduced test case.](https://css-tricks.com/reduced-test-cases/) In order to debug code issues, I need to see actual code in a browser.
13 | 3. The browser and OS that you're using.
14 | 
15 | ## Asking a question
16 | 
17 | Before asking, please **make sure the question hasn't already been asked** by searching GitHub's issues section.
18 | 
19 | ## Submitting a Pull Request
20 | 
21 | Please make sure your code meets the following code standards:
22 | 
23 | - Camel case for JavaScript variables.
24 | - [Object-Oriented CSS](http://www.slideshare.net/stubbornella/object-oriented-css) for CSS selectors.
25 | - Favor readable code over brevity. The build process will reduce size, so opt for readability. (ex. `var navigation` is better than `var n`)
26 | - Order CSS properties alphabetically.
27 | - Hard tabs.
28 | 
29 | Before submitting, make sure that you've:
30 | 
31 | - Updated the version number using semantic versioning.

 1 | # HTML Minify
 2 | HTML Minify is a plugin for WordPress that compresses the HTML output to reduce file size and improve performance. It's forked from a [script by DVS](http://www.intert3chmedia.net/2011/12/minify-html-javascript-css-without.html).
 3 | 
 4 | [Download HTML Minify](https://github.com/cferdinandi/html-minify/archive/master.zip)
 5 | 
 6 | 
 7 | 
 8 | ## Getting Started
 9 | 
10 | Getting started with HTML Minify is as simple as installing a plugin:
11 | 
12 | 1. Upload the `html-minify` folder to the `/wp-content/plugins/` directory.
13 | 2. Activate the plugin through the Plugins menu in WordPress.
14 | 
15 | And that's it, you're done. Nice work! You change what gets minified under "Settings" in the Admin Dashboard.
16 | 
17 | It's recommended that you also install the [GitHub Updater plugin](https://github.com/afragen/github-updater) to get automattic updates.
18 | 
19 | 
20 | 
21 | ## Known Issues
22 | 
23 | It's been reported that [data URIs](https://developer.mozilla.org/en-US/docs/Web/HTTP/data_URIs) may [break the minifier](https://github.com/cferdinandi/html-minify/issues/2). This has not been consistently duplicated, nor is their a fix available, but is something to be aware of.
