 ## Usage
 
 ### Default End-of-Line Sequence
-The workflow uses `LF` as the fallback end-of-line sequence. The default end-of-line sequence can be configured either through [`.gitattributes`](https://www.git-scm.com/docs/gitattributes) or through the parameter `default-eol`. The following example sets the fallback end-of-line sequence to `CRLF`.
+The workflow enforces `LF` for all files in the index. `autocrlf=true` modifies files in the working tree rather than the index and thus does not affect the workflow. The following example configures the workflow to enforce `CRLF` instead.

 ### Steps
 1. Create the following files,
-    - `lf-lf.txt` - A file containing one LF.
-    - `lf-crlf.txt` - A file containing one CRLF.
-    - `lf-mixed.txt` - A file containing one LF and one CRLF.
-    - `crlf-lf.txt` - A file containing one LF.
-    - `crlf-crlf.txt` - A file containing one CRLF.

+    - `lf.txt` - A file containing one LF.
+    - `crlf.txt` - A file containing one CRLF.
+    - `mixed.txt` - A file containing one LF and one CRLF.
 1. Create or copy a binary file, such as an image or an archive.
 1. Run the command `git config core.autocrlf false`
-1. Create a file named `.gitattributes` with the following contents,
-    ```ini
-    lf-*.txt text eol=lf
-    crlf-*.txt text eol=crlf
-    ```
-1. All other files created such as `.gitattributes` and workflow files must be using the LF end-of-line sequence.

 1. Commit and push to GitHub.
 
 ### Outputs
 1. Workflow triggers.
 1. Workflow fails.
 1. The workflow should flag the following files,
-    - `lf-crlf.txt`.
-    - `lf-mixed.txt`.
-    - `crlf-lf.txt`.
-    - `crlf-mixed.txt`.
+    - `crlf.txt`.
+    - `mixed.txt`.
 1. The workflow should not flag the following files,
-    - `lf-lf.txt`.
-    - `crlf-crlf.txt`.
+    - `lf.txt`.

-### Steps
-1. Replace the contents of the file named `.gitattributes` with the following,
-    ```ini
-    *-lf.txt text eol=lf
-    *-crlf.txt text eol=crlf
-    ```
-1. Remove the files ending in `mixed`.
-1. Commit and push to GitHub.

-### Outputs
-1. Workflow triggers.
-1. Workflow succeeds.

 ## Action succeeds when non-compliant files are fixed
 
 ### Steps
-1. Replace the contents of the file named `.gitattributes` with the following,
-    ```ini
-    lf-*.txt text eol=lf
-    crlf-*.txt text eol=crlf
