Prerequisites

1. Install Docker Desktop

Docker Desktop is a free application that installs Docker on Windows with a graphical interface. It includes everything Questbee needs.

1. Go to the official Docker Desktop download page:
   docs.docker.com/desktop/install/windows-install/ ↗
2. Click Docker Desktop for Windows to download the installer (Docker Desktop Installer.exe).
3. Run the installer. When asked, leave the default options selected and click Next through each step.
4. When the installer asks about WSL 2, click OK — this is the recommended backend and installs automatically.
5. After installation, click Close and restart. Your computer will restart.
6. After restarting, Docker Desktop will open automatically. Wait for the whale icon 🐋 in the taskbar to stop animating — that means Docker is ready.

2. Install Git

Git is a tool for downloading and managing code. You will use it once to download Questbee.

1. Go to the official Git for Windows download page:
   git-scm.com/download/win ↗
2. The download starts automatically. Run the installer (Git-x.x.x-64-bit.exe).
3. Click Next through all steps — the default options are correct for most users.
4. On the step "Choosing the default editor" you can pick any editor. If unsure, leave the default and continue.
5. Click Install, then Finish.

1. Install Docker Desktop

Docker Desktop is a free application that installs Docker on macOS with a graphical interface.

1. Go to the official Docker Desktop download page:
   docs.docker.com/desktop/install/mac-install/ ↗
2. Download the correct version for your chip (Apple Silicon or Intel).
3. Open the downloaded .dmg file. Drag the Docker icon to your Applications folder.
4. Open Docker from Applications. macOS will ask if you want to open it — click Open.
5. Docker will ask for your Mac password to install its components. Enter your password and click Install Helper.
6. Wait for the whale icon 🐋 in the menu bar to stop animating — Docker is ready when it's still.

2. Install Git

Most Macs already have Git. Open Terminal (search for "Terminal" in Spotlight with ⌘ Space) and run:

git --version

If you see a version number (e.g. git version 2.39.3), Git is already installed — skip to the Verify section below.

If a dialog pops up asking to install Command Line Developer Tools, click Install and wait for it to finish. Git will be included.

If neither happens, install Git via Homebrew. First install Homebrew if you don't have it:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Then install Git:

brew install git

1. Install Docker Engine

On Linux, Docker runs as a background service (no graphical interface needed). The commands below are for Ubuntu / Debian. For other distributions, see the official guide linked at the end.

Step 1 — Remove any old versions:

sudo apt-get remove docker docker-engine docker.io containerd runc

Step 2 — Install using the official convenience script (easiest method):

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

Step 3 — Allow your user to run Docker without sudo:

sudo usermod -aG docker $USER
newgrp docker

Step 4 — Install Docker Compose v2 (included with recent Docker installs, but just in case):

sudo apt-get install docker-compose-plugin

2. Install Git

Ubuntu / Debian:

sudo apt-get update && sudo apt-get install -y git

Fedora / RHEL / CentOS:

sudo dnf install -y git
