+# CCExtractor Docker image
+
+This dockerfile prepares a minimalist Docker image with CCExtractor. It compiles CCExtractor from sources following instructions from the [Compilation Guide](https://github.com/CCExtractor/ccextractor/blob/master/docs/COMPILATION.MD).
+
+You can install the latest build of this image by running `docker pull CCExtractor/ccextractor`
+
+## Build
+
+You can build the Docker image directly from the Dockerfile provided in [docker](https://github.com/CCExtractor/ccextractor/tree/master/docker) directory of CCExtractor source
+
+```bash
+$ git clone https://github.com/CCExtractor/ccextractor.git && cd ccextractor
+$ cd docker/
+$ docker build -t ccextractor .
+```
+
+## Usage
+
+The CCExtractor Docker image can be used in several ways, depending on your needs.
+
+```bash
+# General usage
+$ docker run ccextractor:latest <features>
+```
+
+1. Process a local file & use `-o` flag
+
+To process a local video file, mount a directory containing the input file inside the container:
+
+```bash
+# Use `-o` to specifying output file
+$ docker run --rm -v $(pwd):$(pwd) -w $(pwd) ccextractor:latest input.mp4 -o output.srt
+
+# Alternatively use `--stdout` feature
+$ docker run --rm -v $(pwd):$(pwd) -w $(pwd) ccextractor:latest input.mp4 --stdout > output.srt
+```
+
+Run this command from where your input video file is present, and change `input.mp4` & `output.srt` with the actual name of files.
+
+2. Enter an interactive environment
+
+If you need to run CCExtractor with additional options or perform other tasks within the container, you can enter an interactive environment:
+bash
+
+```bash
+$ docker run --rm -it --entrypoint='sh' ccextractor:latest
+```
+
+This will start a Bash shell inside the container, allowing you to run CCExtractor commands manually or perform other operations.
+
+### Example
+
+I run help command in image built from `dockerfile`
+
+```bash
+$ docker build -t ccextractor .
+$ docker run --rm ccextractor:latest --help
+```
+
+This will show the `--help` message of CCExtractor tool
+From there you can see all the features and flags which can be used.
