 **Required** The environment variable name to export, ex. `CURRENT_BRANCH`, `GIT_BRANCH`. Default `"GIT_BRANCH_NAME"`.
 
+On `pull_request` event, two additional environment variables are exported for `HEAD` and `BASE`. The env names are suffixed with `_HEAD` and `_BASE`. By default, they are `GIT_BRANCH_NAME_HEAD` and `GIT_BRANCH_NAME_BASE`.
+
 ## Outputs
 
 ### `git_branch_name`
 
 The current Git branch name.
 
+On `pull_request` event, it is the same as `git_branch_name_head`.
+
+### `git_branch_name_head`
+
+The current Git branch name at `HEAD`. Only available on `pull_request` event.
+
+### `git_branch_name_base`
+
+The current Git branch name at `BASE`. Only available on `pull_request` event.

 ```yaml
-uses: petehouston/github-actions-query-branch-name@v1.1
+uses: petehouston/github-actions-query-branch-name@v1.2
 ```
 
 Export to custom environment variable, ex. `MY_BRANCH`
 ```yaml
-uses: petehouston/github-actions-query-branch-name@v1.1
+uses: petehouston/github-actions-query-branch-name@v1.2
