+  </a>
+</p>
+
+Based on the npm package [generate-licence-file](https://www.npmjs.com/package/generate-license-file).
+
+## Usage
+
+To run the Action, supply your package.json path as `input`, and your desired output file as `output`.
+
+```yaml
+jobs:
+  myJob:
+    steps:
+      - uses: actions/checkout@v2
+
+      - uses: generate-licence-file@latest
+        name: Generate License File
+        with:
+          input: "./package.json"
+          output: "./third-party-licenses.txt"
+```
+
+You can also specify which line ending you would like it to use, either `windows` for ` crlf` or `posix` for `lf`. If you don't supply one it will use the build agents default.
+
+```yaml
+jobs:
+  myJob:
+    steps:
+      - uses: actions/checkout@v2
+
+      - uses: generate-licence-file@latest
+        name: Generate License File
+        with:
+          input: "./package.json"
+          output: "./third-party-licenses.txt"
+          lineEnding: posix
+```
+
+## Building the action yourself
+
+```bash
+npm install
+npm run build
+```
+
+A Husky pre-commit hook will automatically build and commit the dist directory on each commit to ensure that the committed JavaScript code is always up to date.
