## See it in Action (click to expand)

#### Explain Code

Visually select a block of text in your buffer, and have ChatGPT tell you what it does! Optionally customize the prompt included in your request.

#### Summarize a Block of Text

Sick of reading documents? Have ChatGPT summarize what your buffer says.

#### Explain Code ex. 2

Have questions on the full buffer? Shortcut to include everything in your request, no visual selection necessary.

## ☄ Getting started

1. Sign up for paid account at https://platform.openai.com/signup
1. Be sure to note pricing! It is recommended to use something like privacy.com to make sure that you do not accidentally exceed your price limit. Note that there is a separate charge for _ChatGPT_ usage and _API_ usage. We're after _API_.
1. After adding payment info, copy your API key and set it as an environment variable in your shell. Here is a command that will add this to your `.zshrc` file:
```
echo 'export CHAT_GPT_API_KEY=' >> ~/.zshrc
```
1. Install the Plugin using your favorite package manager as described above

## ⚙ Configuration

* Sensible default config values have been set. Customize values using the the standard `setup` function.
* See `M.options` [here]([url](https://github.com/tdfacer/explain-it.nvim/blob/main/lua/explain-it/config.lua#L5)) for a full list of options.
