+## Activating CLI Autocomplete
+
+### Using CLI Autocomplete
+Using the following sequence of commands for each shell will activate the autocompletion feature for the CLI. 
+#### Bash
+1. Install openai if not installed yet.
+```shell
+pip install openai
+```
+
+2. Configure your shell to support global auto completion for python scripts by running:
+```shell
+activate-global-python-argcomplete
+```
+3. Restart your terminal
+
+4. Register ‘openai’ command for argument completion by running:
+```shell
+eval "$(register-python-argcomplete openai)"
+```
+
+Alternatively, run this command to enable argcomplete persistently, eliminating the need to run the eval command every time the terminal is restarted or reloaded. Restart your terminal after using this command.
+```shell
+register-python-argcomplete openai >> ~/.bashrc
+```
+
+5. Try on CLI
+```shell
+openai <TAB>
+```
+
+#### Powershell
+1. Install openai if not installed already.
+```shell
+pip install openai
+```
+2. Create new completion file: 
+```shell
+register-python-argcomplete --shell powershell openai > ~/openai.psm1
+```
+
+3. Open the [``$PROFILE``](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_profiles?view=powershell-7.4&viewFallbackFrom=powershell-7.3#how-to-create-a-profile) by running ``notepad $PROFILE`` and add this following line:
+```shell
+Import-Module  "~/openai.psm1"
+```
+
+4. Restart the terminal and try:
+```shell
+openai <TAB>
+```
