+
+## Docker Development Setup
+
+You can also use docker to launch and manage a development server, in a similar fashion to managing a production server.
+
+There are some key differences compared to the docker production setup:
+
+- The docker image is built locally, rather than being downloaded from DockerHub
+- The docker image points to the source code on your local machine, instead of cloning from GitHub
+- The django webserver is used, instead of running behind Gunicorn
+- The server will automatically reload when code changes are detected
+
+The [InvenTree docker image](https://github.com/inventree/InvenTree/blob/master/docker/Dockerfile) uses a [multi-stage build](https://docs.docker.com/develop/develop-images/multistage-build/) process to allow both production and development setups from the same image. The key difference is that the production image is pre-built using InvenTree source code from GitHub, while the development image uses the source code from your local machine (allowing live code updates).
+
+### Docker Compose
+
+A docker compose script for running a development server is provided at `docker/docker-compose.dev.yml`:
+
+### Setup
+
+#### Download Source Code
+
+First download the source code from GitHub:
+
+```
+git clone git@github.com:inventree/InvenTree.git
+cd inventree/docker
+```
+
+#### Edit docker-compose File
+
+Now, edit the `docker-compose.dev.yml` file (in the `docker` subdirectory), ensuring that the `src` volume points to the directory on your local machine where you have just cloned the source code.
+
+#### Launch Development Server
+
+Launch the development server with the following command:
+
+```
+docker-compose -f docker-compose.dev.yml up -d inventree-server
+```
+
+This launches the InvenTree server (in development mode) and also performs the following tasks:
+
+- Creates an sqlite database
+- Creates a `config.yaml` file
+- Creates a `secret_key.txt` file
+- Creates `inventree_media` directory for uploaded media files
+- Creates `inventree_static` directory for storing static files
+
+!!! info "Wait for Install"
+    The first time the server is launched, it will take a few minutes to install the required python packages.
+
+Check that the server is running at [http://localhost:8000](http://localhost:8000)
+
+#### Create Superuser
+
+Once the development server is running, create a superuser (admin) account:
+
+```
+docker-compose -f docker-compose.dev.yml run inventree-server bash
+```
+
+Inside the docker shell, run the following commands:
+
+```
+source ./inventree-docker-dev/bin/activate
+invoke superuser
+```
+
+#### Start Background Worker
+
+To launch the backround worker process:
+
+```
+docker-compose -f docker-compose.dev.yml up -d inventree-worker
+```
