Luke Stein d4ae108d9b Docs: Add instructions for file management via curl (#282)
Per a [reddit
thread](https://www.reddit.com/r/xteinkereader/comments/1q0fk9r/if_using_crosspoint_firmware_you_can_upload_using/),
the file manager can be accessed via curl.

Given file upload or deletion via curl may be useful for advanced users,
I've added instructions.

# CrossPoint User Guide
Welcome to the **CrossPoint** firmware. This guide outlines the hardware controls, navigation, and reading features of the device.
## 1. Hardware Overview
The device utilises the standard buttons on the Xtink X4 (in the same layout as the manufacturer firmware, by default):
### Button Layout
| Location | Buttons |
| --------------- | ---------------------------------------------------- |
| **Bottom Edge** | **Back**, **Confirm**, **Left**, **Right** |
| **Right Side** | **Power**, **Volume Up**, **Volume Down**, **Reset** |
Button layout can be customized in **[Settings](#35-settings)**.
---
## 2. Power & Startup
### Power On / Off
To turn the device on or off, **press and hold the Power button for half a second**. In **[Settings](#35-settings)** you can configure the power button to trigger on a short press instead of a long one.
To reboot the device (for example if it's frozen, or after a firmware update), press and release the Reset button, and then hold the Power button for a few seconds.
### First Launch
Upon turning the device on for the first time, you will be placed on the **[Home](#31-home-screen)** screen.
> [!NOTE]
> On subsequent restarts, the firmware will automatically reopen the last book you were reading.
---
## 3. Screens
### 3.1 Home Screen
The Home Screen is the main entry point to the firmware. From here you can navigate to **[Reading Mode](#4-reading-mode)** with the most recently read book, **[Book Selection](#32-book-selection)**, **[Settings](#35-settings)**, or the **[File Upload](#34-file-upload-screen)** screen.
### 3.2 Book Selection
The Book Selection acts as a folder and file browser.
* **Navigate List:** Use **Left** (or **Volume Up**), or **Right** (or **Volume Down**) to move the selection cursor up and down through folders and books. You can also long-press these buttons to scroll a full page up or down.
* **Open Selection:** Press **Confirm** to open a folder or read a selected book.
### 3.3 Reading Mode
See [Reading Mode](#4-reading-mode) below for more information.
### 3.4 File Upload Screen
The File Upload screen allows you to upload new e-books to the device. When you enter the screen, you'll be prompted with a WiFi selection dialog and then your X4 will start hosting a web server.
See the [webserver docs](./docs/webserver.md) for more information on how to connect to the web server and upload files.
> [!TIP]
> Advanced users can also manage files programmatically or via the command line using `curl`. See the [webserver docs](./docs/webserver.md) for details.
### 3.5 Settings
The Settings screen allows you to configure the device's behavior. There are a few settings you can adjust:
- **Sleep Screen**: Which sleep screen to display when the device sleeps:
- "Dark" (default) - The default dark sleep screen
- "Light" - The same default sleep screen, on a white background
- "Custom" - Custom images from the SD card, see [Sleep Screen](#36-sleep-screen) below for more information
- "Cover" - The book cover image (Note: this is experimental and may not work as expected)
- **Status Bar**: Configure the status bar displayed while reading:
- "None" - No status bar
- "No Progress" - Show status bar without reading progress
- "Full" - Show status bar with reading progress
- **Extra Paragraph Spacing**: If enabled, vertical space will be added between paragraphs in the book. If disabled, paragraphs will not have vertical space between them, but will have first-line indentation.
- **Short Power Button Click**: Whether to trigger the power button on a short press or a long press.
- **Reading Orientation**: Set the screen orientation for reading:
- "Portrait" (default) - Standard portrait orientation
- "Landscape CW" - Landscape, rotated clockwise
- "Inverted" - Portrait, upside down
- "Landscape CCW" - Landscape, rotated counter-clockwise
- **Front Button Layout**: Configure the order of the bottom edge buttons:
- Back, Confirm, Left, Right (default)
- Left, Right, Back, Confirm
- Left, Back, Confirm, Right
- **Side Button Layout**: Swap the order of the up and down volume buttons from Previous/Next to Next/Previous. This change is only in effect when reading.
- **Reader Font Family**: Choose the font used for reading:
- "Bookerly" (default) - Amazon's reading font
- "Noto Sans" - Google's sans-serif font
- "Open Dyslexic" - Font designed for readers with dyslexia
- **Reader Font Size**: Adjust the text size for reading; options are "Small", "Medium", "Large", or "X Large".
- **Reader Line Spacing**: Adjust the spacing between lines; options are "Tight", "Normal", or "Wide".
- **Reader Paragraph Alignment**: Set the alignment of paragraphs; options are "Justified" (default), "Left", "Center", or "Right".
- **Time to Sleep**: Set the duration of inactivity before the device automatically goes to sleep.
- **Refresh Frequency**: Set how often the screen does a full refresh while reading to reduce ghosting.
- **Check for updates**: Check for firmware updates over WiFi.
### 3.6 Sleep Screen
You can customize the sleep screen by placing custom images in specific locations on the SD card:
- **Single Image:** Place a file named `sleep.bmp` in the root directory.
- **Multiple Images:** Create a `sleep` directory in the root of the SD card and place any number of `.bmp` images inside. If images are found in this directory, they will take priority over the `sleep.bmp` file, and one will be randomly selected each time the device sleeps.
> [!NOTE]
> You'll need to set the **Sleep Screen** setting to **Custom** in order to use these images.
> [!TIP]
> For best results:
> - Use uncompressed BMP files with 24-bit color depth
> - Use a resolution of 480x800 pixels to match the device's screen resolution.
