+
+Github Action for building executables with PyInstaller
+
+To build your application, you need to specify where your source code is via the `path` argument, this defaults to `src`.
+
+The source code directory should have your `.spec` file that PyInstaller generates. If you don't have one, you'll need to run PyInstaller once locally to generate it.
+
+If the `src` folder has a `requirements.txt` file, the packages will be installed into the environment before PyInstaller runs.
+
+## Example usage
+
+Include this in your `.github/workflows/main.yaml`:
+
+```yaml
+- name: PyInstaller Windows
+  uses: JackMcKew/pyinstaller-action-windows@master
+```
+
+## Full Example
+
+Here is an entire workflow for:
+
+- Packaging an application with PyInstaller
+- Uploading the packaged executable as an artifact
+
+``` yaml
+
+name: Package Application with Pyinstaller
+
+on:
+  push:
+    branches: [ master ]
+  pull_request:
+    branches: [ master ]
+
+jobs:
+  build:
+
+    runs-on: ubuntu-latest
+
+    steps:
+    - uses: actions/checkout@v2
+
+    - name: Package Application
+      uses: JackMcKew/pyinstaller-action-windows@master
+      with:
+        path: src
+
+    - uses: actions/upload-artifact@v2
+      with:
+        name: name-of-artifact
+        path: src/dist/windows
+```
