-- Fixed the issue when a voice is selected, the voice mixer tries to pre-select that voice and ignores existing profiles.
-- Fixed the error while renaming the default "New profile" in the voice mixer.
-- Prevented using special characters in the profile name to avoid conflicts.
-- Improved invalid profile handling in the voice mixer.
+- Better approach for detemining the correct configuration folder for Linux and MacOS, using platformdirs.

 With voice mixer, you can create custom voices by mixing different voice models. You can adjust the weight of each voice and save your custom voice as a profile for future use. The voice mixer allows you to create unique and personalized voices. (Huge thanks to [@jborza](https://github.com/jborza) for making this possible through his contributions in [#5](https://github.com/denizsafak/abogen/pull/5))
 
+## `About Chapter Markers`
+When you process ePUB or PDF files, abogen converts them into text files stored in your temporary directory. When you click "Edit," you're actually modifying these converted text files. In these text files, you'll notice tags that look like this:
+
+```
+<CHAPTER_MARKER:Chapter Title>
+```
+These are chapter markers. They are automatically added when you process ePUB or PDF files, based on the chapters you select. They serve an important purpose:
+-  Allow you to split the text into separate audio files for each chapter
+-  Save time by letting you reprocess only specific chapters if errors occur, rather than the entire file
+
+You can manually add these markers to plain text files for the same benefits. Simply include them in your text like this:
+
+```
+<CHAPTER_MARKER:Introduction>  
+This is the beginning of my text...  
+
+<CHAPTER_MARKER:Main Content>  
+Here's another part...  
+```
+When you process the text file, abogen will detect these markers automatically and ask if you want to save each chapter separately and create a merged version.

+## `Docker Guide`
+If you want to run Abogen in a Docker container:
+1) [Download the repository](https://github.com/denizsafak/abogen/archive/refs/heads/main.zip) and extract, or clone it using git.
+2) Go to `abogen` folder. You should see `Dockerfile` there.
+3) Open your termminal in that directory and run the following commands:
+
+```bash
+# Build the Docker image:
+docker build --progress plain -t abogen .
+
+# Note that building the image may take a while.
+# After building is complete, run the Docker container:
+
+# Windows
+docker run --name abogen -v %cd%:/shared -p 5800:5800 -p 5900:5900 --gpus all abogen
+
+# Linux
+docker run --name abogen -v $(pwd):/shared -p 5800:5800 -p 5900:5900 --gpus all abogen
+
+# MacOS
+docker run --name abogen -v $(pwd):/shared -p 5800:5800 -p 5900:5900 abogen
+
+# We expose port 5800 for use by a web browser, 5900 if you want to connect with a VNC client.
+```
+
+Abogen launches automatically inside the container. 
+- You can access it via a web browser at `http://localhost:5800` or connect to it using a VNC client at `localhost:5900`.
+- You can use `/shared` directory to share files between your host and the container.
+- For later use, start it with `docker start abogen` and stop it with `docker stop abogen`.
