+**Settings** screen, or **File Upload** screen.
+
+### 3.2 Book Selection (Read)
+
+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.
 * **Open Selection:** Press **Confirm** to open a folder or read a selected book.
 
+### 3.3 Reading Screen
+
+See [4. 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.
+
+### 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, options are:
+  - "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 [3.6 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, options are:
+  - "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 word 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, options are:
+  - "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, options are:
+  - "Bck, Cnfrm, Lft, Rght" (default) - Back, Confirm, Left, Right
+  - "Lft, Rght, Bck, Cnfrm" - Left, Right, Back, Confirm
+  - "Lft, Bck, Cnfrm, Rght" - Left, Back, Confirm, Right
+- **Side Button Layout**: Swap the order of the 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, options are:
+  - "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".
+- **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.png` 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.

+# Web Server Guide
+
+This guide explains how to connect your CrossPoint Reader to WiFi and use the built-in web server to upload EPUB files from your computer or phone.
+
+## Overview
+
+CrossPoint Reader includes a built-in web server that allows you to:
+
+- Upload EPUB files wirelessly from any device on the same WiFi network
+- Browse and manage files on your device's SD card
+- Create folders to organize your ebooks
+- Delete files and folders
+
+## Prerequisites
+
+- Your CrossPoint Reader device
+- A WiFi network
+- A computer, phone, or tablet connected to the **same WiFi network**
+
+---
+
+## Step 1: Accessing the WiFi Screen

+2. Select the **WiFi** option
+3. The device will automatically start scanning for available networks
+
+---
+
+## Step 2: Connecting to WiFi
+
+### Viewing Available Networks
+
+Once the scan completes, you'll see a list of available WiFi networks with the following indicators:
+
+- **Signal strength bars** (`||||`, `|||`, `||`, `|`) - Shows connection quality
+- **`*` symbol** - Indicates the network is password-protected (encrypted)

+
+---
+
+## Troubleshooting
+
+### Cannot See the Device on the Network
+
+**Problem:** Browser shows "Cannot connect" or "Site can't be reached"
+
+**Solutions:**
+
+1. Verify both devices are on the **same WiFi network**
+   - Check your computer/phone WiFi settings
+   - Confirm the CrossPoint Reader shows "Connected" status
+2. Double-check the IP address
+   - Make sure you typed it correctly
+   - Include `http://` at the beginning
+3. Try disabling VPN if you're using one
+4. Some networks have "client isolation" enabled - check with your network administrator
+
+### Connection Drops or Times Out
+
+**Problem:** WiFi connection is unstable
+
+**Solutions:**
+
+1. Move closer to the WiFi router
+2. Check signal strength on the device (should be at least `||` or better)
+3. Avoid interference from other devices
+4. Try a different WiFi network if available
+
+### Upload Fails
+
+**Problem:** File upload doesn't complete or shows an error
+
+**Solutions:**
+
+1. Ensure the file is a valid `.epub` file
+2. Check that the SD card has enough free space
+3. Try uploading a smaller file first to test
+4. Refresh the browser page and try again
+
+### Saved Password Not Working
+
+**Problem:** Device fails to connect with saved credentials
+
+**Solutions:**
+
+1. When connection fails, you'll be prompted to "Forget Network"
+2. Select **Yes** to remove the saved password
+3. Reconnect and enter the password again
+4. Choose to save the new password
+
+---
+
+## Security Notes
+
+- The web server runs on port 80 (standard HTTP)
+- **No authentication is required** - anyone on the same network can access the interface
+- The web server is only accessible while the WiFi screen shows "Connected"
+- The web server automatically stops when you exit the WiFi screen
+- For security, only use on trusted private networks
+
+---
+
+## Technical Details
+
+- **Supported WiFi:** 2.4GHz networks (802.11 b/g/n)
+- **Web Server Port:** 80 (HTTP)
+- **Maximum Upload Size:** Limited by available SD card space
+- **Supported File Format:** `.epub` only
+- **Browser Compatibility:** All modern browsers (Chrome, Firefox, Safari, Edge)
+
+---
+
+## Tips and Best Practices
+
+1. **Organize with folders** - Create folders before uploading to keep your library organized
+2. **Check signal strength** - Stronger signals (`|||` or `||||`) provide faster, more reliable uploads
+3. **Upload multiple files** - You can upload files one at a time; the page refreshes after each upload
+4. **Use descriptive names** - Name your folders clearly (e.g., "SciFi", "Mystery", "Non-Fiction")
+5. **Keep credentials saved** - Save your WiFi password for quick reconnection in the future
+6. **Exit when done** - Press **Back** to exit the WiFi screen and save battery
+
+---
+
+## Exiting WiFi Mode
+
+When you're finished uploading files:
+
+1. Press the **Back** button on your CrossPoint Reader
+2. The web server will automatically stop
+3. WiFi will disconnect to conserve battery
+4. You'll return to the previous screen
+
+Your uploaded files will be immediately available in the file browser!

+-----------------------------------------------------------
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS

+"Reserved Font Name" refers to any names specified as such after the
+copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as

+binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font
+Name(s) unless explicit written permission is granted by the corresponding
+Copyright Holder. This restriction only applies to the primary font name as
+presented to the users.

+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded,
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS

+Holder(s) under this license and clearly marked as such. This may
+include source files, build scripts and documentation.

+"Reserved Font Name" refers to any names specified as such after the
+copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as

+Software, subject to the following conditions:
+
+1) Neither the Font Software nor any of its individual components,
+in Original or Modified Versions, may be sold by itself.
+
+2) Original or Modified Versions of the Font Software may be bundled,

+UBUNTU FONT LICENCE Version 1.0
+-------------------------------
+
+PREAMBLE
+This licence allows the licensed fonts to be used, studied, modified and
+redistributed freely. The fonts, including any derivative works, can be
+bundled, embedded, and redistributed provided the terms of this licence
+are met. The fonts and derivatives, however, cannot be released under
+any other licence. The requirement for fonts to remain under this
+licence does not require any document created using the fonts or their
+derivatives to be published under this licence, as long as the primary
+purpose of the document is not to be a vehicle for the distribution of
+the fonts.
+
+DEFINITIONS
+"Font Software" refers to the set of files released by the Copyright
+Holder(s) under this licence and clearly marked as such. This may
+include source files, build scripts and documentation.
+
+"Original Version" refers to the collection of Font Software components
+as received under this licence.
+
+"Modified Version" refers to any derivative made by adding to, deleting,
+or substituting -- in part or in whole -- any of the components of the
+Original Version, by changing formats or by porting the Font Software to
+a new environment.
+
+"Copyright Holder(s)" refers to all individuals and companies who have a
+copyright ownership of the Font Software.
+
+"Substantially Changed" refers to Modified Versions which can be easily
+identified as dissimilar to the Font Software by users of the Font
+Software comparing the Original Version with the Modified Version.
+
+To "Propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification and with or without charging
+a redistribution fee), making available to the public, and in some
+countries other activities as well.
+
+PERMISSION & CONDITIONS
+This licence does not grant any rights under trademark law and all such
+rights are reserved.
+
+Permission is hereby granted, free of charge, to any person obtaining a
+copy of the Font Software, to propagate the Font Software, subject to
+the below conditions:
+
+1) Each copy of the Font Software must contain the above copyright
+notice and this licence. These can be included either as stand-alone
+text files, human-readable headers or in the appropriate machine-
+readable metadata fields within text or binary files as long as those
+fields can be easily viewed by the user.
+
+2) The font name complies with the following:
+(a) The Original Version must retain its name, unmodified.
+(b) Modified Versions which are Substantially Changed must be renamed to
+avoid use of the name of the Original Version or similar names entirely.
+(c) Modified Versions which are not Substantially Changed must be
+renamed to both (i) retain the name of the Original Version and (ii) add
+additional naming elements to distinguish the Modified Version from the
+Original Version. The name of such Modified Versions must be the name of
+the Original Version, with "derivative X" where X represents the name of
+the new work, appended to that name.
+
+3) The name(s) of the Copyright Holder(s) and any contributor to the
+Font Software shall not be used to promote, endorse or advertise any
+Modified Version, except (i) as required by this licence, (ii) to
+acknowledge the contribution(s) of the Copyright Holder(s) or (iii) with
+their explicit written permission.
+
+4) The Font Software, modified or unmodified, in part or in whole, must
+be distributed entirely under this licence, and must not be distributed
+under any other licence. The requirement for fonts to remain under this
+licence does not affect any document created using the Font Software,
+except any version of the Font Software extracted from a document
+created using the Font Software may only be distributed under this
+licence.
+
+TERMINATION
+This licence becomes null and void if any of the above conditions are
+not met.
+
+DISCLAIMER
+THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
