+⚠️ Protobuf classes are generated, do NOT modify the classes manually ⚠️
+
+## Setup

 ```sh
+sudo apt install protobuf-compiler
+```
+

+
+```sh
+sudo pecl install protobuf

+
+- Edit the *.proto file
+
+>Reference: [protocol-buffers/docs/proto3](https://developers.google.com/protocol-buffers/docs/proto3)
+
+- Run the following cli command:
+
+```bash
 protoc --proto_path=app/Protobuf/ --php_out=. app/Protobuf/GoogleAuth.proto
 ```
+
+Protoc will generate the files in `app/Protobuf` while we want them to be in `App/protobuf`.
+
+- Moves the files from `app/Protobuf` to `App/protobuf`
+- Update the namespace of the moved files to match their new location
