+# AutoMarker
+
+AutoMarker is a Python-based GUI application that allows users to place markers on a Premiere Pro active sequence based on a music file's tempo. The application uses the librosa library to detect beats in the audio file and the pymiere library to interact with Adobe Premiere Pro.
+
+## Features
+
+- Detects beats in an audio file and places markers on a Premiere Pro active sequence.
+- Supports audio files in formats such as .wav, .mp3, .flac, .ogg, and .aiff.
+- Allows users to specify the frequency of markers and an offset for the first beat.
+- Checks if Adobe Premiere Pro is running and provides feedback to the user.
+
+## Installation
+
+AutoMarker is packaged as a standalone executable using PyInstaller. This means that the user does not need to install Python or any dependencies to run the application.
+
+To install AutoMarker, follow these steps:
+
+1. Download the executable file for your operating system from the provided source.
+2. Run the downloaded file to install AutoMarker.
+
+## Usage
+
+After installing AutoMarker, you can launch it from your system's application menu. The application will open in a new window.
+
+To use AutoMarker, follow these steps:
+
+1. Click the "Select audio file" button to choose an audio file.
+2. If Adobe Premiere Pro is running, click the "Create markers" button to place markers on the active sequence based on the audio file's tempo.
+3. You can adjust the frequency of markers and the offset for the first beat using the sliders.
+
+## Troubleshooting
+
+If you encounter any issues while using AutoMarker, ensure that Adobe Premiere Pro is installed and running. If the problem persists, please get in touch for further assistance.
+
+## Contributing
+
+We welcome contributions to AutoMarker. If you have a feature request, bug report, or want to improve the documentation, please submit an issue or pull request on our GitHub repository.
