+# GETTING STARTED
+
+Ontime consists of 3 distinct parts
+- __client__: A React app for Ontime's UI and web clients 
+- __electron__: An electron app which facilitates the cross-platform distribution of Ontime
+- __server__: A node application which handles the domains services and integrations
+
+The steps below will assume you have locally installed the necessary dependencies. 
+Other dependencies will be installed as part of the setup
+- __node__ (>=16.16)
+- __pnpm__ (>=7)
+- __docker__ (only necessary to run and build docker images)
+
+## LOCAL DEVELOPMENT
+
+The electron app is only necessary to distribute an installable version of the app and is not required for local development.
+Locally, we would need to run both the React client and the node.js server in development mode
+
+From the project root, run the following commands
+- __Install the project dependencies__ by running `pnpm i`
+- __Run dev mode__ by running `turbo dev`
+
+## CREATE AN INSTALLABLE FILE (Windows | MacOS | Linux)
+
+Ontime uses Electron to distribute the application.
+You can generate a distribution for your OS by running the following steps.
+
+From the project root, run the following commands
+- __Install the project dependencies__ by running `pnpm i`
+- __Build the UI and server__ by running `turbo build`
+- __Create the package__ by running `turbo dist-win`, `turbo dist-mac` or `turbo dist-linux`
+
+The build distribution assets will be at `.apps/electron/dist`
+
+## DOCKER
+
+Ontime provides a docker-compose file to aid with building and running docker images.
+While it should allow for a generic setup, it might need to be modified to fit your infrastructure.
+
+From the project root, run the following commands
+- __Install the project dependencies__ by running `pnpm i`
+- __Build docker image from__ by running `docker build -t getontime/ontime`
+- __Run docker image from compose__ by running `docker-compose up -d`
+
+Other useful commands
+- __List running processes__ by running `docker ps`
+- __Kill running process__ by running `docker kill <process-id>`
