 The Docker image currently works on Windows and Linux, optionally supporting NVIDIA GPUs.
 
 ## General Remarks
-- The resulting Docker image is 22 GB in size. Building might require even more disk space temporarily.
-- Build time depends on your hardware and internet connection. Expect at least 10min to be normal.

+- The resulting Docker image is 21 GB in size. Building might require even more disk space temporarily.
+    - Another 15 GB is required for building DeepSpeed
+- Build time depends on your hardware and internet connection. Expect at least 20-30min to be normal for a full build.
+  - This includes building the conda environment as well as DeepSpeed, which is the basis for the alltalk Docker image.
+- The Docker build for alltalk:
   - Downloads XTTS as default TTS engine
   - Enables RVC by default
   - Downloads all supported RVC models

   - Example: `docker-build.sh --tts_model piper`

 ### Arguments for `docker-start.sh`
 - `--config` lets you choose a config JSON file which can subset of `confignew.json`. This allows you to change only 
   few values and leave the rest as defined in the default `confignew.json` file.
-  - Example: `docker-build.sh --config /my/config/file.json` with content `{"branding": "My Brand "}` will just change

     the branding in `confignew.json`.
 - `--voices` lets you add voices for the TTS engine in WAV format. You have to specify the folder containing all
   voice files.

+  - Example: `docker-start.sh --voices /my/voices/dir`
 - `--rvc_voices` similar to voices, this option lets you pick the folder containing the RVC models.

+- `--tag` allows to choose the docker tag of the image to run. Defaults to `latest`.

 - Since the above commands only address the most important options, you might pass additional arbitrary docker commands
     to the `docker-start.sh`.
