+By default the action will fail on any pull request that contains a
+vulnerable dependency, regardless of the severity level. You can override this behavior by
+using the `fail-on-severity` option, which will cause a failure on any pull requests that introduce vulnerabilities of the specified severity level or higher. The possible values are: `critical`, `high`, `moderate`, or `low`. The
+action defaults to `low`.
 
-#### Example
-
-Start by specifying that you will be using an external configuration file:
+This example will only fail on pull requests with `critical` and `high` vulnerabilities:
 
 ```yaml
 - name: Dependency Review
   uses: actions/dependency-review-action@v2
   with:
-    config-file: './.github/dependency-review-config.yml'
+    fail-on-severity: high
 ```
 
-And then create the file in the path you just specified:
+### Licenses
+
+You can set the action to fail on pull requests based on the licenses of the dependencies
+they introduce. With `allow-licenses` you can define the list of licenses
+your repository will accept. Alternatively, you can use `deny-licenses` to only
+forbid a subset of licenses. These options are not supported on GHES.
+
+You can use the [Licenses
+API](https://docs.github.com/en/rest/licenses) to see the full list of
+supported licenses. Use the `spdx_id` field for every license you want
+to filter. A couple of examples:
 
 ```yaml
-fail-on-severity: 'critical'
-allow-licenses:
-  - 'GPL-3.0'
-  - 'BSD-3-Clause'
-  - 'MIT'
+# only allow MIT-licensed dependents
+- name: Dependency Review
+  uses: actions/dependency-review-action@v2
+  with:
+    allow-licenses: MIT
 ```
 
-### Considerations
+```yaml
+# Block Apache 1.1 and 2.0 licensed dependents
+- name: Dependency Review
+  uses: actions/dependency-review-action@v2
+  with:
+    deny-licenses: Apache-1.1, Apache-2.0
+```
 
-- Checking for licenses is not supported on Enterprise Server.
-- The action will only accept one of the two `license` parameters; an error will be raised if you provide both.
-- We don't have license information for all of your dependents. If we can't detect the license for a dependency **we will inform you, but the action won't fail**.
+**Important**
+
+- The action will only accept one of the two parameters; an error will
+  be raised if you provide both.
+- By default both parameters are empty (no license checking is
+  performed).
+- We don't have license information for all of your dependents. If we
+  can't detect the license for a dependency **we will inform you, but the
