-# autoflake_action
+# GitHub autoflake Action
-Automatically runs the autoflake command against any commit/ pull request created
+
+This GitHub action automatically removes unused imports and variables from your Python code using [autoflake](https://pypi.org/project/autoflake/).
+
+## Usage
+### Parameters
+The following parameters can be used in your custom action configuration.
+
+| Parameter | Required | Default | Description |
+| - | - | - | - |
+| commit_message | :x: | 'Removed unused imports and variables' | Custom git commit message |
+| commit_options | :x: | - | Custom git commit options |
+| file_pattern | :x: | '*' | Custom file pattern for `git add` |
+| checkpath | :x: | '.' | The path autoflake checks |
+| no_commit | :x: | False | Avoid committing, if used in a pipeline |
+| options | :x: | ' ' | Parameters to use with autoflake |
+| dry | :x: | false | Dry-run the action to fail when detecting uncompliant files, instead of automatically fixing them. |
+
+
+### Example
+
+This is a simple usage example of this script:
+
+```yaml
+# This action works with pull requests and pushes
+name: Continuous Integration
+
+on:
+  pull_request:
+  push:
+    branches:
+    - master
+
+jobs:
+  build:
+    runs-on: ubuntu-latest
+
+    steps:
+    - uses: actions/checkout@v3
+    - uses: creyD/action_autoflake@master
+      env:

+```
