 This plugin integrates a ChatGPT O1 model workflow into Neovim. It allows you to:
 
 1. Generate prompts containing:
-   - An **initial prompt** (from `.chatgpt_config.yaml` or `chatgpt_config.yaml`)
-   - A list of directories (also specified in `.chatgpt_config.yaml` or `chatgpt_config.yaml`) from which it gathers the project structure and file contents
-   - **Interactive file selection** if enabled, so you can pick exactly which directories to include
-   - Any **initial files** you define (e.g., `README.md`, etc.)

 ## New Key Features
 
 - **Step-by-Step Prompting** (`enable_step_by_step: true`):  
-  If the request grows too large (exceeds `token_limit`), the plugin automatically generates a special prompt asking the model to split the task into smaller steps, working through them one by one. This approach helps you stay within the model’s maximum token limit without having to manually break things apart.
+  If the generated prompt grows too large (exceeding the configured `prompt_char_limit`), the plugin automatically produces a special prompt asking the model to split the task into smaller steps. This ensures you remain within the model’s maximum token capacity without manually breaking your task apart.
 
-- **Partial Acceptance**: If `partial_acceptance: true`, you can open a buffer that lists the final changes. Remove or comment out lines you don’t want, then only those changes are applied.
+- **Partial Acceptance**:  
+  If `partial_acceptance: true`, you can open a buffer displaying the proposed changes. Remove or comment out lines you do not wish to apply, and only the remaining changes will be executed.
 
-- **Preview Changes**: If `preview_changes: true`, you get a buffer showing proposed changes before you apply them.
+- **Preview Changes**:  
+  If `preview_changes: true`, a buffer will show the proposed changes before they are applied.
 
-- **Interactive File Selection**: If `interactive_file_selection: true`, you choose which directories from `.chatgpt_config.yaml` or `chatgpt_config.yaml` get included in the prompt, reducing token usage.
+- **Interactive File Selection**:  
+  When `interactive_file_selection: true`, you can choose which directories (from your config file) to include in the prompt, thus managing token usage more effectively.
 
-- **Improved Debug**: If `improved_debug: true`, debug logs go into a dedicated `ChatGPT_Debug_Log` buffer for easier reading.
+- **Include File Contents**:  
+  A new configuration flag `include_file_contents` (default: `false`) lets you include the entire contents of the project files in the prompt. When enabled, the plugin gathers and appends the file contents from the selected directories. It counts the total characters and, if the combined file contents exceed the `prompt_char_limit`, it notifies you to disable this feature to avoid exceeding the model’s capacity.
+
+- **Improved Debug**:  
+  If `improved_debug: true`, detailed debug logs are sent to a dedicated `ChatGPT_Debug_Log` buffer for easier review.

 ## Usage
 
 1. **`:ChatGPT`**  
-   - If `interactive_file_selection` is on, you’ll pick directories to include in a buffer named `ChatGPT_File_Selection`.
-   - Save & close with `:wq`, `:x`, or `:bd` (you don’t have to use `:q`).
-   - If `enable_step_by_step` is on and the prompt might exceed `token_limit`, the plugin will generate instructions prompting the model to address each step separately.
+   - If `interactive_file_selection` is enabled, you will select directories via a buffer (named `ChatGPT_File_Selection`).
+   - Save and close the buffer with `:wq`, `:x`, or `:bd` (no need to use `:q`).
+   - If `enable_step_by_step` is active and the prompt might exceed `prompt_char_limit`, the plugin will generate a step-by-step instruction prompt.
 
 2. **Paste Prompt to ChatGPT**  
-   - If the task is split into steps, simply copy/paste them one by one into ChatGPT.

 3. **`:ChatGPTPaste`**  
-   - The plugin reads the YAML from your clipboard. If it requests more files, it might again suggest a step-by-step approach.  
-   - If final changes are provided:
-     - Optionally preview them (`preview_changes`).  
-     - Optionally partially accept them (`partial_acceptance`).  
-     - Then the plugin writes/deletes files as specified.
+   - The plugin reads the YAML response from your clipboard. If additional files are requested, a step-by-step approach might be suggested.
+   - When final changes are provided:
+     - You can optionally preview them (`preview_changes`).
+     - You can optionally partially accept them (`partial_acceptance`).
+     - Finally, the plugin applies file writes or deletions as specified in the YAML.
 
 ## Troubleshooting & Tips
-- Adjust `token_limit` in `.chatgpt_config.yaml` as needed.
-- If partial acceptance is confusing, remember to remove or prepend `#` to lines you don’t want before saving and closing the buffer.
-- If step-by-step prompting occurs, ensure you follow each prompt the model provides in the correct order.  
-- Check `ChatGPT_Debug_Log` if `improved_debug` is on, or the Neovim messages if `debug` is on, for detailed info.
-- You can close the selection or prompt buffers at any time with commands like `:bd`, `:x`, or `:wq`. No need to rely on `:q`.
