 The GO Feature Flag Command Line is a CLI tool to interact with GO Feature Flag in your terminal.  
 For now it supports the following commands:
+
 - `evaluate` to evaluate feature flags directly in your terminal
 - `lint` to validate a configuration file format.
 
 ## How to install the cli
 
 ### Install using Homebrew (mac and linux)
+
 ```shell
 brew tap thomaspoignant/homebrew-tap
 brew install go-feature-flag-cli
 ```
 
 ### Install using docker
+
 ```shell
 docker pull gofeatureflag/go-feature-flag-cli
 ```
-More information about the usage of the container in the [dockerhub page](https://hub.docker.com/r/gofeatureflag/go-feature-flag-cli).

 # How to use the command line
 
 **`go-feature-flag-cli`**  is a command line tool.
 
 ## How to evaluate a flag
+
+The evaluate command allows you to evaluate a feature flag or inspect the configuration of your retriever using
+`--check-mode`
+
+```shell
+go-feature-flag-cli evaluate [OPTIONS]
+```
+
+### Key Flags
+
+| Flag           | Shorthand | Description                                                                                                                     | Default |

+| `--check-mode` |           | Check only mode - when set, the command will not perform any <br/>evaluation and returns the configuration of spanned retriever | false   |
+
+Supported values for `--kind` are:
+
+- `file`
+- `http`
+- `github`
+- `gitlab`
+- `s3`
+- `googleStorage`
+- `configmap` (kubernetes)
+- `mongodb`

+to: https://github.com/thomaspoignant/go-feature-flag/issues/4023.
+
+### Retriever specific flags
+
+The aforementioned `--kind` parameter is used to determine the retriever to use. The semantic meaning of other flags
+depends on that one, for
+example `--path` parameter is used to specify local file when `--kind` being `file` but when `--kind` being `github` it
+is used to specify
+the path to the remote file.

+As mentioned above the `--config` flag is deprecated and we encourage you to use the `--path` flag instead. For example
+the following command:
+
 ```shell
 go-feature-flag-cli evaluate --config="<location_of_your_flag_configuration_file>" --flag="<name_of_your_flag_to_evaluate>" --ctx='<evaluation_ctx_as_json_string>'
 ```
 
+may be replaced by:
+
+```shell
+go-feature-flag-cli evaluate --kind="file" --path="<location_of_your_flag_configuration_file>" --flag="<name_of_your_flag_to_evaluate>" --ctx='<evaluation_ctx_as_json_string>'
+```
+
 ## How to lint a configuration file
+
 ```shell
 go-feature-flag-cli lint <location_of_your_flag_configuration_file> --format="<yaml or json or toml>"
 ```
