-Automatically label new pull requests based on the paths of files being changed.
+Automatically label new pull requests based on the paths of files being changed or the branch name.
 
 ## Usage
 
 ### Create `.github/labeler.yml`
 
-Create a `.github/labeler.yml` file with a list of labels and [minimatch](https://github.com/isaacs/minimatch) globs to match to apply the label.
+Create a `.github/labeler.yml` file with a list of labels and config options to match and apply the label.
 
-The key is the name of the label in your repository that you want to add (eg: "merge conflict", "needs-updating") and the value is the path (glob) of the changed files (eg: `src/**/*`, `tests/*.spec.js`) or a match object.
+The key is the name of the label in your repository that you want to add (eg: "merge conflict", "needs-updating") and the value is a match object.
 
 #### Match Object
 
-For more control over matching, you can provide a match object instead of a simple path glob. The match object is defined as:
+The match object allows control over the matching options, you can specify the label to be applied based on the files that have changed or the name of either the base branch or the head branch. For the changed files options you provide a [path glob](https://github.com/isaacs/minimatch#minimatch), and for the branches you provide a regexp to match against the branch name.
 
+The base match object is defined as:
 ```yml
-- any: ['list', 'of', 'globs']
-  all: ['list', 'of', 'globs']
+- changed-files: ['list', 'of', 'globs']
+- base-branch: ['list', 'of', 'regexps']
+- head-branch: ['list', 'of', 'regexps']
 ```
 
-One or both fields can be provided for fine-grained matching. Unlike the top-level list, the list of path globs provided to `any` and `all` must ALL match against a path for the label to be applied.
+There are two top level keys of `any` and `all`, which both accept the same config options:
+```yml
+- any:
+  - changed-files: ['list', 'of', 'globs']
+  - base-branch: ['list', 'of', 'regexps']
+  - head-branch: ['list', 'of', 'regexps']
+- all:
+  - changed-files: ['list', 'of', 'globs']
+  - base-branch: ['list', 'of', 'regexps']
+  - head-branch: ['list', 'of', 'regexps']
+```
 
+One or all fields can be provided for fine-grained matching.
 The fields are defined as follows:
-* `any`: match ALL globs against ANY changed path
-* `all`: match ALL globs against ALL changed paths
+* `all`: all of the provided options must match in order for the label to be applied
+* `any`: if any of the provided options match then a label will be applied
+* `base-branch`: match regexps against the base branch name
+* `changed-files`: match glob patterns against the changed paths
+* `head-branch`: match regexps against the head branch name
 
-A simple path glob is the equivalent to `any: ['glob']`. More specifically, the following two configurations are equivalent:
+If a base option is provided without a top-level key then it will default to `any`. More specifically, the following two configurations are equivalent:
 ```yml
 label1:
-- example1/*
+- changed-files: example1/*
 ```
 and
 ```yml
 label1:
-- any: ['example1/*']
+- any:
+  - changed-files: ['example1/*']
 ```
 
-From a boolean logic perspective, top-level match objects are `OR`-ed together and individual match rules within an object are `AND`-ed. Combined with `!` negation, you can write complex matching rules.
+From a boolean logic perspective, top-level match objects, and options within `all`  are `AND`-ed together and individual match rules within the `any` object are `OR`-ed. If path globs are combined with `!` negation, you can write complex matching rules.
 
 #### Basic Examples
