-<h2>Installation</h2>
-<p>The mod supports <a href="https://files.minecraftforge.net/">Forge</a> and <a href="https://fabricmc.net/">Fabric</a> (*) mod loaders. Follow either mod loader's installation guide, then <a href="https://www.curseforge.com/minecraft/mc-mods/custom-window-title/files">download the mod file</a> for your Minecraft version and mod loader, and install it into the <strong>.minecraft/mods</strong> folder.</p>
-<p>(*) Fabric API is <strong>not</strong> required.</p>
-<h2>Configuration</h2>
-<p>Run the game once to create the configuration file. By default, the window title will be set to <strong>Minecraft <em>&lt;version&gt;</em></strong>. Unlike in vanilla 1.15.2 onwards, the title will not change when you enter a world/server.</p>
-<p>To change the title or icon, navigate to the <strong>.minecraft/config</strong> folder, and open <strong>customwindowtitle-client.toml</strong> in a text editor. You will see the following entries:</p>
-<p><span style="font-family: courier new,courier,monospace;">title = '<span style="color: #808000;">Minecraft {mcversion}</span>'</span><br /> <span style="font-family: courier new,courier,monospace;">icon16 = ''</span><br /> <span style="font-family: courier new,courier,monospace;">icon32 = ''</span></p>
-<p>Only edit text inside quotes or apostrophes.</p>
-<h3>Changing the Title</h3>
-<p>You can use the following special tokens in the <em>title</em> configuration entry:</p>
-<ul>
-  <li><strong>{mcversion}</strong> - current Minecraft version</li>
-  <li><strong>{modversion:<span style="text-decoration: underline;">modid</span>}</strong> - version of installed mod with the identifier <em>modid</em></li>
-</ul>
-<p>If any of the tokens aren't working, search the game log for <strong>CustomWindowTitle</strong> and you should see the reason, otherwise please file an issue on the <a href="https://github.com/chylex/Minecraft-Window-Title/issues">issue tracker</a> with as many details as possible.</p>
-<h3>Changing the Icon</h3>
-<p>You must create two PNG images with sizes 16x16 and 32x32 pixels. The images <strong>must be saved with transparency</strong> even if they don't use it, <strong>otherwise the icons will appear corrupted</strong>. In Krita for example, you must check <em>Store alpha channel (transparency)</em> when saving the image.</p>
-<p>The <em>icon16</em> and <em>icon32</em> configuration entries point to the PNG files relative to the <strong>.minecraft/config</strong> folder. For example, if you place the two icons in a folder named <em>customwindowtitle</em> as follows:</p>
-<ul>
-  <li><span style="font-family: courier new, courier, monospace;">.minecraft/config/<span style="color: #008080;">customwindowtitle-client.toml</span></span></li>
-  <li><span style="font-family: courier new, courier, monospace;">.minecraft/config/<span style="color: #808000;">customwindowtitle/icon16.png</span></span></li>
-  <li><span style="font-family: courier new, courier, monospace;">.minecraft/config/<span style="color: #808000;">customwindowtitle/icon32.png</span></span></li>
-</ul>
-<p>Then, the two icon entries should look like this:</p>
-<p><span style="font-family: courier new,courier,monospace;">icon16 = '<span style="color: #808000;">customwindowtitle/icon16.png</span>'</span><br /> <span style="font-family: courier new,courier,monospace;">icon32 = '<span style="color: #808000;">customwindowtitle/icon32.png</span>'</span></p>
-<p><strong>Custom icons require Custom Window Title 1.1.0 or newer.</strong></p>
-<h2>Screenshots</h2>
-<p>These screenshots were taken using the following example configuration:</p>
-<p><span style="font-family: courier new,courier,monospace;">title = "<span style="color: #808000;">Minecraft {mcversion} - Custom Window Title {modversion:customwindowtitle}</span>"</span></p>

 You can use the following special tokens in the _title_ configuration entry:

 ### Changing the Icon
 
-You must create two PNG images with sizes 16x16 and 32x32 pixels. The images **must be saved with transparency** even if they don't use it, **otherwise the icons will appear corrupted**. In Krita for example, you must check _Store alpha channel (transparency)_ when saving the image.

+## Installation
+
+The mod supports [NeoForge](https://neoforged.net/) and [Fabric](https://fabricmc.net/) (*) mod loaders. Follow either mod loader's installation guide, then [download the mod file](https://www.curseforge.com/minecraft/mc-mods/custom-window-title/files) for your Minecraft version, and install it into the `.minecraft/mods` folder.
+
+(*) Fabric API is **not** required.
+
+## Configuration
+
+Run the game once to create the configuration file. By default, the window title will be set to **Minecraft _<version>_**. Unlike in vanilla 1.15.2 onwards, the title will not change when you enter a world/server.
+
+To change the title or icon, navigate to the `.minecraft/config` folder, and open `customwindowtitle-client.toml` in a text editor. You will see the following entries:
+
+```toml
+title = 'Minecraft {mcversion}'  
+icon16 = ''  
+icon32 = ''
+```
+
+Only edit text inside quotes or apostrophes.
+
+### Changing the Title
+
+You can use the following special tokens in the _title_ configuration entry:
+
+* `{mcversion}` - current Minecraft version
+* `{modversion:mod_id}` - version of installed mod with the identifier `mod_id`
+* `{username}` - current username
+
+If any of the tokens aren't working, search the game log for **CustomWindowTitle** and you should see the reason, otherwise please file an issue on the [issue tracker](https://github.com/chylex/Minecraft-Window-Title/issues) with as many details as possible.
+
+### Changing the Icon
+
+#### Minecraft 1.21+
+
+**This feature is only available in Custom Window Title 1.4.0 and newer.**
+
+Create a square PNG image whose dimensions are a power of two, such as 32x32 or 48x48. Put the PNG file into the `.minecraft/config` folder, either directly or into a subfolder.
+
+The icon **must be saved with transparency** even if it doesn't use it, otherwise the icon may be corrupted or not appear at all. In Krita, for example, you must check _Store alpha channel (transparency)_ when saving.
+
+The _icon_ configuration entry points to the PNG file relative to `.minecraft/config`.
+
+For example, if you placed the icon into `.minecraft/config/customwindowtitle/icon.png`, then the configuration entry should look like this:
+
+```toml
+icon = 'customwindowtitle/icon.png'
+```
+
+#### Minecraft 1.20
+
+This feature is not available in Minecraft 1.20.
+
+#### Minecraft 1.19 and older
+
+Instead of one `icon` configuration entry, there are two configuration entries `icon16` and `icon32` for icons with dimensions 16x16 and 32x32.
+
+## Screenshots
+
+These screenshots were taken using the following example configuration:
+
+```toml
+title = "Minecraft {mcversion} - Custom Window Title {modversion:customwindowtitle}"
+```

+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
