 Exact version  | `1.0.2`                                                            | You can specify the exact version of a package.
-Range          | `>=1.0` `>=1.0,<2.0` <code>&gt;=1.0,&lt;1.1 &#124; &gt;=1.2</code> | By using comparison operators you can specify ranges of valid versions. Valid operators are `>`, `>=`, `<`, `<=`, `!=`. <br />You can define multiple ranges. Ranges separated by a space (` `) or comma (`,`) will be treated as a **logical AND**. A pipe (<code>&#124;</code>) or double pipe will be treated as a **logical OR**. AND has higher precedence than OR.
+Range          | `>=1.0` `>=1.0 <2.0` <code>&gt;=1.0 &lt;1.1 &#124;&#124; &gt;=1.2</code> | By using comparison operators you can specify ranges of valid versions. Valid operators are `>`, `>=`, `<`, `<=`, `!=`. <br />You can define multiple ranges. Ranges separated by a space (` `) or comma (`,`) will be treated as a **logical AND**. A double pipe (<code>&#124;&#124;</code>) will be treated as a **logical OR**. AND has higher precedence than OR.
+Hyphen Range   | `1.0 - 2.0` | Inclusive set of versions. Partial versions on the right include are completed with a wildcard. For example `1.0 - 2.0` is equivalent to `>=1.0.0 <2.1` as the `2.0` becomes `2.0.*`. On the other hand `1.0.0 - 2.1.0` is equivalent to `>=1.0.0 <=2.1.0`.
 Wildcard       | `1.0.*`                                                            | You can specify a pattern with a `*` wildcard. `1.0.*` is the equivalent of `>=1.0,<1.1`.
 Tilde Operator | `~1.2`                                                             | Very useful for projects that follow semantic versioning. `~1.2` is equivalent to `>=1.2,<2.0`. For more details, read the next section below.
