+# Proposal: Add Official CLI for Harbor
+
+Author: Akshat/[akshatdalton](https://github.com/akshatdalton)
+
+## Abstract
+
+This proposal aims to add the official CLI for Harbor. It will have basic features like user login and other CRUD operations like create project, get project, list projects, etc.
+
+## Background
+
+There are some unofficial CLI projects to interact with Harbor API, and now Harbor wants to provide official support for CLI.
+
+## Goals
+
+- Implement official CLI for Harbor.
+- Support basic CRUD operations like create project, get project, list projects, etc.
+
+## Implementation
+
+### Directory structure
+
+```
+cli/
+├── main.go
+├── go.sum
+├── go.mod
+├── README.md
+├── .gitignore
+└── cmd/
+    ├── root.go
+    ├── create_project.go
+    ├── delete_project.go
+    ├── login.go
+    ├── logout.go
+    ├── util.go
+    ├── .
+    ├── .
+    └── .
+```
+
+I will be using [cobra](https://github.com/spf13/cobra) to make this CLI tool and it will have the directory structure as shown above. For each of the commands, either we can have a single file or an individual sub-package for them.
+
+E.g.:<br>
+
+- for a single file -
+
+    ```
+    cmd/
+    ├── create_project.go
+    ├── create_project_test.go
+    ├── delete_project.go
+    ├── delete_project_test.go
+    ├── .
+    ├── .
+    ├── .
+    ```
+
+- for an individual sub-package -
+
+    ```
+    cmd/
+    ├── project
+        ├── project.go
+        ├── create_project.go
+        ├── create_project_test.go
+        ├── delete_project.go
+        ├── delete_project_test.go
+        ├── .
+        ├── .
+        ├── .
+    ```
+
+<br>
+
+User credentials will be stored in `~/.harbor/auth.yaml` upon sign in and the same will be used to read the credentials to make the API calls.
+
+<br>
+
+[harbor/go-client](https://github.com/goharbor/go-client) will be used to make any API calls for any given server address.
