 ## Setup your development environment
+### Container based development flow (recommended and the easiest)
+All you need is to intall [Docker Engine 20.11+](https://docs.docker.com/engine/install/) on your local machine and run `pnpm dev:container`. It will build the base image for Coolify and start the development server inside Docker. All required ports (3000, 3001) will be exposed to your host.
+
 ### Github codespaces
 
 If you have github codespaces enabled then you can just create a codespace and run `pnpm dev` to run your the dev environment. All the required dependencies and packages has been configured for you already.
 
 ### Gitpod
+1. Use [container based development flow](#container-based-development-flow-easiest)
+2. Or setup your workspace manually:
 
-If you have a [Gitpod](https://gitpod.io), you can just create a workspace from this repository, run `pnpm install && pnpm db:push && pnpm db:seed` and then `pnpm dev`. All the required dependencies and packages has been configured for you already.

+> Some packages, just `pack` are not installed in this way. You cannot test all the features. Please use the [container based development flow](#container-based-development-flow-easiest).
 
 ### Local Machine
 > At the moment, Coolify `doesn't support Windows`. You must use `Linux` or `MacOS` or consider using Gitpod or Github Codespaces.
 
-- Due to the lock file, this repository is best with [pnpm](https://pnpm.io). I recommend you try and use `pnpm` because it is cool and efficient!
