 ## Introduction
 This is a PHP library for representing and converting physical units of measure.  The utility of this library is in encapsulating physical quantities in such a way that you don't have to keep track of which unit they're represented in.  For instance:

 ### Project Tags and Versions
-This project follows the guidelines set out in [Semantic Versioning 2.0.0](http://semver.org/spec/v2.0.0.html).  In general, versions are of the form 'X.Y.Z', and increments to X denote backward-incompatible major changes.

 Now any program which uses `Length` will start with the cubits unit already built in.  Note that here we used the more concise linear unit factory method, but the result is equivalent to the expanded form calling the `UnitOfMeasure` constructor, as used above.  Also, notice that the `static` keyword was used instead of the class name, though either would be acceptable in this case.
 
 ### Adding New Physical Quantities
-[Physical quantities](http://en.wikipedia.org/wiki/Physical_quantity) are categories of measurable values, like mass, length, force, etc.
+[Physical quantities](https://en.wikipedia.org/wiki/Physical_quantity) are categories of measurable values, like mass, length, force, etc.
 
 For physical quantities that are not already present in this library, it will be necessary to write a class to support a new one.  All physical quantities implement the `\PhpUnitsOfMeasure\PhysicalQuantityInterface` interface, typically extend the `\PhpUnitsOfMeasure\AbstractPhysicalQuantity` class, and typically have only an `initialize()` method which creates the quantity's units of measure.  See above for typical examples of physical quantity classes and of how to add new units to a quantity class.

 All the tests associated with this project can be manually run with:

 ### CodeSniffer
 Codesniffer verifies that coding standards are being met.  Once the project is built with development dependencies, you can run the checks with:
 
 ``` bash

 ### Continuous Integration
 The above tests are automatically run against Github commits with Travis-CI.
