 # machine-learning-general-purpose
-The GitHub repo for a Dockerhub image that will be updated as new technology is required.
+This is my machine learning and general utility Python image
 
-If you are using a Microsoft Dev Container, you may want to add existing extensions. Note the `customizations:` section below:
+## To use the image from Dockerhub
+I do not manage versions of the dockerfile, so I suggest you perform the following steps:
 
-`.devcontainer/devcontainer.json`
+1. In your repo, add the following line:
 ```
-// For format details, see https://aka.ms/devcontainer.json. For config options, see the
-// README at: https://github.com/devcontainers/templates/tree/main/src/docker-existing-dockerfile
-{
-	"name": "Existing Dockerfile",
-	"build": {
-		// Sets the run context to one level up instead of the .devcontainer folder.
-		"context": "..",
-		// Update the 'dockerFile' property if you aren't using the standard 'Dockerfile' filename.
-		"dockerfile": "../Dockerfile"
-	},
-	// Features to add to the dev container. More info: https://containers.dev/features.
-	// "features": {},
-
-	// Use 'forwardPorts' to make a list of ports inside the container available locally.
-	// "forwardPorts": [],
-
-	// Uncomment the next line to run commands after the container is created.
-	// "postCreateCommand": "cat /etc/os-release",
-
-	// Configure tool-specific properties.
-	"customizations": {
-		"vscode": {
-		  "extensions": [
-			"ms-azuretools.vscode-docker",
-			"ms-toolsai.jupyter",
-			"ms-python.python"
-			]
-		}
-	  }
-
-	// Uncomment to connect as an existing user other than the container default. More info: https://aka.ms/dev-containers-non-root.
-	// "remoteUser": "devcontainer"
-}
-```
+FROM billraymond/machine-learning-general-purpose:latest
+```
+2. Copy over the `./devcontainer` folder from this repo and modify the `configure-git.sh` file to use your user.email and user.name.
+3. Note that you can add, remove, or modify the VSC extensions in the `./devcontainer/devcontainer.json file`
+
+## Customize this container
+If you want to customize the container, I recommend you download the code (ex zip file) so you can use the `./devcontainer` folder and tailor that to your needs as well.
+
+While the requirements for this image may change over time, the devcontainer will include:
+
+1. An LTS version of Ubuntu
+2. The latest version of Python 3 from the APT package manager
+3. Other items may include Git, Tensorflow, Git, h5py, SciKitLearn, and more
+4. Check out the Dockerfile contained in this repo for more details of what is or is not installed
+
+## Example customization
+Here is an example Dockerfile for another repo I manage that adds more capabilities, like OpenAI's API, tabulate, pandoc, markdown, and more. Note that it pulls from the base DockerHub container and then adds more packages to it.
+
+`Dockerfile`
+```
+FROM billraymond/machine-learning-general-purpose:latest
+
+# Install pillow qr code and pillow for graphics manipulation
+RUN pip install --no-cache-dir qrcode[pil] && \
+    pip install --no-cache-dir --upgrade pillow
+
+# Install various tools in support of utilities
+    RUN pip install --no-cache-dir python-pptx \
+                openai \
+                tabulate \
+                pandoc \
+                markdown2 \
+                pdfkit \
+                beautifulsoup4
+RUN apt-get update
+RUN apt-get install -y wkhtmltopdf
+
+RUN rm -rf /var/lib/apt/lists/*
+```
