+
+## Invoke Tool
+
+InvenTree uses the [invoke](https://www.pyinvoke.org/) tool to manage various system administration tasks. Invoke is a powerful python-based task execution tool, which allows for the creation of custom tasks and command-line utilities.
+
+### Installation
+
+InvenTree setup and administration requires that the invoke tool is installed. This is usually installed automatically as part of the InvenTree installation process - however (if you are configuring InvenTree from source) you may need to install it manually.
+
+To install the invoke tool, run the following command:
+
+```
+pip install -U invoke
+```
+
+### Minimum Version
+
+The minimum required version of the invoke tool is `{{ config.extra.min_invoke_version }}`.
+
+To determine the version of invoke you have installed, run either:
+
+```
+invoke --version
+```
+```
+python -m invoke --version
+```
+
+If you are running an older version of invoke, ensure it is updated to the latest version:
+
+```
+pip install -U invoke
+```
+
+### Running from Command Line
+
+To run the `invoke` tool from the command line, you must be in the top-level InvenTree source directory. This is the directory that contains the [tasks.py]({{ sourcefile("tasks.py") }}) file.
+
+### Running in Docker Mode
+
+If you have installed InvenTree via [docker](./docker_install.md), then you need to ensure that the `invoke` commands are called from within the docker container context.
+
+For example, to run the `update` task, you might use the following command to run the `invoke` command - using the `docker compose` tool.
+
+```
+docker compose run --rm inventree-server invoke update
+```
+
+!!! note "Docker Compose Directory"
+    The `docker compose` command should be run from the directory where the `docker-compose.yml` file is located.
+
+Alternatively, to manually run the command within the environment of the running docker container:
+
+```
+docker exec -it inventree-server invoke update
+```
+
+!!! note "Container Name"
+    The container name may be different depending on how you have configured the docker environment.
+
+### Running in Installer Mode
+
+If you have installed InvenTree using the [package installer](./installer.md), then you need to prefix all `invoke` commands with `inventree run`.
+
+For example, to run the `update` task, use:
+
+```
+inventree run invoke update
+```
+
+## Available Tasks
+
+To display a list of the available InvenTree administration actions, run the following commands from the top level source directory:
+
+```
+invoke --list
+```
+
+This provides a list of the available invoke commands - also displayed below:
+
+```
+{{ invoke_commands() }}
+```
+
+### Task Information
+
+Each task has a brief description of its purpose, which is displayed when running the `invoke --list` command. To find more detailed information about a specific task, run the command with the `--help` flag.
+
+For example, to find more information about the `update` task, run:
+
+```
+invoke update --help
+```
+
+### Internal Tasks
+
+Tasks with the `int.` prefix are internal tasks, and are not intended for general use. These are called by other tasks, and should generally not be called directly.
+
+### Developer Tasks
+
+Tasks with the `dev.` prefix are tasks intended for InvenTree developers, and are also not intended for general use.
+
+## Common Issues
+
+Below are some common issues that users may encounter when using the `invoke` tool, and how to resolve them.
+
+### Command 'invoke' not found
+
+If the `invoke` command does not work, it means that the invoke tool has not been [installed correctly](#installation).
+
+### Invoke Version
+
+If the installed version of invoke is too old, users may see error messages during the installation procedure, such as:
+
+- *'update' did not receive all required positional arguments!*
+- *Function has keyword-only arguments or annotations*
+
+Ensure that the installed version of invoke is [up to date](#minimum-version).
+
+### Can't find any collection named 'tasks'
+
+It means that the `invoke` tool is not able to locate the InvenTree task collection.
+
+- If running in docker, ensure that you are running the `invoke` command from within the [docker container](#running-in-docker-mode)
+- If running in installer mode, ensure that you are running the `invoke` command with the [correct prefix](#running-in-installer-mode)
+- If running via command line, ensure that you are running the `invoke` command from the [correct directory](#running-from-command-line)
