+As build dependencies change over time, you have to synchronize your development environment with the current specification. In order to pull in all required UI dependencies (NPM packages), issue:
 
 * `make dep-ui` or `make dep-ui-local`
 
+These commands run `pnpm install --frozen-lockfile` command, which only brings package versions that are defined in the `pnpm-lock.yaml` file without trying to resolve and download new package versions.
+
+### Updating UI build dependencies
+
+If you need to add new UI dependencies or update existing ones you need 
+to run a `pnpm` command in the ./ui directory to resolve and download new packages. 
+
+You can run it in the docker container using the `make run-pnpm` make target.
+
+For example, to add new dependency `newpackage` you may run command like
+
+```shell
+make run-pnpm PNPM_COMMAND="add newpackage --ignore-scripts"
+```
+
+To upgrade an existing package:
+
+```shell
+make run-pnpm PNPM_COMMAND="update existingpackage@1.0.2 --ignore-scripts"
+```
+
+Please consider using best security practices when adding or upgrading
+NPM dependencies, such as this
+[guide](https://github.com/lirantal/npm-security-best-practices/blob/main/README.md).

 ### Generate API glue code and other assets
 
 Argo CD relies on Google's [Protocol Buffers](https://developers.google.com/protocol-buffers) for its API, and this makes heavy use of auto-generated glue code and stubs. Whenever you touched parts of the API code, you must re-generate the auto generated code.
