+- Go 1.19+ (for making changes in the Go code)
 - Node 16+ (for making changes in the Admin UI)

 ```
 git clone https://github.com/your_username/pocketbase.git

 > It is recommended to create a new branch from master for each of your bugfixes and features.
 > This is required if you are planning to submit multiple PRs in order to keep the changes separate for review until they eventually get merged.

 ## Making changes in the Go code
 
 PocketBase is distributed as a Go package, which means that in order to run the project you'll have to create a Go `main` program that imports the package.
 
-The repository already includes such program, located in `/examples/base`, that is also used for the prebuilt executables.

 So, let's assume that you already done some changes in the PocketBase Go code and you want now to run them:

 You could open the browser and access the running Admin UI at `http://localhost:3000`.
 
 Since the Admin UI is just a client-side application, you need to have the PocketBase backend server also running in the background (either manually running the `examples/base/main.go` or download a prebuilt executable).
 
+> [!NOTE]
 > By default, the Admin UI is expecting the backend server to be started at `http://localhost:8090`, but you could change that by creating a new `ui/.env.development.local` file with `PB_BACKEND_URL = YOUR_ADDRESS` variable inside it.
 
 Every change you make in the Admin UI should be automatically reflected in the browser at `http://localhost:3000` without reloading the page.
