+To install Keyper, ensure you have Go installed on your machine.
+If you haven't installed Go yet, you can follow the [official Go installation instructions](https://go.dev/doc/install).
 
 ```
 go install github.com/SameerJadav/keyper@latest
 ```
 
 This will install a Go binary that automatically binds to your `$GOPATH`.
 
-## Usage Example
+## Usage
 
 Keyper is designed for simplicity. It's a [grug brain tool](https://grugbrain.dev/#grug-on-tools).
 
-### Save Environment Variables
-
-**Command:**
+### Save environment variables
 
 ```
-keyper set <project> <key=value> ...
+keyper set todo-list -e prod -f .env
 ```
 
-**Example:**
-
-```
-keyper set my-project DATABASE_URL=postgresql://localhost/mydb DATABASE_AUTH_TOKEN=42069
-```
-
-Saves the specified key-value pairs as environment variables for the given project, overwriting existing variables with the same keys.
-
-### Retrieve Environment Variables
+This command sets environment variables for the "todo-list" project.
+It uses the production environment (-e prod) and loads variables from .env file (-f .env).
+You can also add `key=value` pairs directly in the command instead of using a file.
+Run `keyper set --help` for more information.
 
-**Command:**
+### Retrieve environment variables
 
 ```
-keyper get <project>
+keyper get todo-list -e dev -o .env
 ```
 
-**Example:**
+This command retrieves environment variables for the "todo-list" project.
+It fetches variables from the development environment (-e dev) and saves them to a file named .env (-o .env).
+If -e is not specified, it retrieves variables for all environments.
+If -o is not specified, variables are printed to the console.
+Run `keyper get --help` for more information.
 
-```
-keyper get my-project
-```
-
-Displays the saved environment variables for the specified project.
+### Remove environment variables
 
 ```
-DATABASE_URL=postgresql://localhost/mydb
-DATABASE_AUTH_TOKEN=42069
+keyper remove todo-list -force -e prod API_KEY SECRET_TOKEN
 ```
 
-### Remove Environment Variables
+This command removes specified environment variables (API_KEY and SECRET_TOKEN) from the "todo-list" project in the production environment (-e prod).
+The -force flag skips the confirmation prompt.
+If -e is omitted, it removes the variables from all environments.
+Run `keyper remove --help` for more information.
 
-**Command:**
+**Note: Use with caution as this action cannot be undone.**
 
-```
-keyper remove <project> <key> ...
-```
-
-**Example:**
+### Purge project or environment
 
 ```
-keyper remove my-project DATABASE_URL
+keyper purge todo-list -force -e prod
 ```
 
-Permanently removes the specified environment variables from the given project.
-
-### Purge Project and its Variables
+This command purges the "todo-list" project's production environment (-e prod).
+The -force flag skips the confirmation prompt.
+If -e is omitted, it purges the entire project and all its environments.
+Run `keyper purge --help` for more information.
 
-**Command:**
-
-```
-keyper purge <project> ...
-```
-
-**Example:**
-
-```
-keyper purge my-project
-```
-
-Permanently removes the entire project and all its associated environment variables. Use this command with caution.
-
-### Pro-Tip
-
-You can easily export environment variables to a `.env` file by just redirecting the result of the `keyper get` command to an `.env` file.
-
-```
-keyper get my-project > .env
-```
+**Note: Use with caution as this action cannot be undone.**
