 # About
 TAB aims to be a superior all-in-one minecraft plugin for displaying information that outperforms all 
-similar plugins in terms of features, performance, compatibility and support.  
+similar plugins in terms of features, performance and compatibility.  
 More information can be found at [Why TAB?](https://github.com/NEZNAMY/TAB/wiki/Why-TAB%3F) wiki page.
 
-# Distribution
-As of TAB 3.0.0, released with MC 1.18 (November 30th, 2021), there is no free / premium
-version anymore. Only one version of the plugin exists now, which contains all implemented features
-and is available to everyone for free. However, customer support is only provided to 
-customers who have purchased the plugin (see [Customer support](#customer-support)).  
+# Download
+### Releases
+You can download full releases from [GitHub releases](https://github.com/NEZNAMY/TAB/releases), 
+[SpigotMC](https://www.spigotmc.org/resources/57806/), [Modrinth](https://modrinth.com/plugin/tab-was-taken) or [BuiltByBit](https://builtbybit.com/resources/20631).
+
+### Dev builds
+Plugin's development is continuous and contains lots of small changes/fixes not worthy of being called a full
+update, therefore development builds are being created and eventually a full update is released when enough changes are made.  
+If you want to benefit from a recent change in the code before official release, you can download development builds
+from [GitHub actions](https://github.com/NEZNAMY/TAB/actions) (you must be logged into GitHub to be able to download it).  
 
 # Compiling
-Compilation requires JDK 17 and up.  
+Compilation requires JDK 21 and up.  
 To compile the plugin, run `./gradlew build` from the terminal.  
 Once the plugin compiles, grab the jar from `/jar/build/libs/` folder.  
 The universal jar contains all modules for all supported platforms.
 
-# Customer support
-Unlike with other projects where requirements and level of support provided are unclear,
-we provide a clear answer to what kind of service you will or will not receive. Some projects don't
-even clearly state if they are free or paid. While they are listed as paid on spigot, they have
-a free download link in description, which can be confusing.  
-Support is also quite often "we have a discord server, but don't ping devs for support", suggesting
-there is no official support, just the community.
-
-In TAB, everything is clearly defined. **Downloads are free, but services are paid.**  
-The plugin is free to download for everyone. The only exception might be occasional update delays
-for free users once a year.  
-Customer support, however, is only provided to customers who have formally purchased a copy 
-of the plugin on any of the websites the plugin is being sold on:  
-* [BuiltByBit](https://builtbybit.com/resources/14009/)
-* [Polymart](https://polymart.org/resource/484)
-  
-After purchasing, you can request assistance via either private messages on the website where you
-have purchased it, or using [TAB's Discord server](https://discord.gg/EaSvdk6) (which is highly 
-preferred, since the communication will be much faster thanks to notifications and more).  
-* We use a ticket system, which allows us to effectively track any amount of unresolved problems.
-No more questions getting lost in the sea of messages from other people asking. Tickets are only closed
-after user confirmed all of their questions were answered and then receive a transcript of the ticket
-from the bot after ticket is closed into private messages (unless user is blocking them).
-* We do not rely on the community helping, which often makes things even worse. We know people have
-better things to do than helping random people with a random plugin, especially when most people only
-have a very basic knowledge of the plugin, not being able to answer more complicated problems.
-* We have notifications enabled and reply as soon as possible. We do not have the server muted unlike
-most mods on most servers who only check it when they are really bored, give a wiki link and 
-disappear again.
-* As the developer, I do not rely on helpers providing support instead of me. They are handy as
-I am obviously not available 24/7, but I do not intentionally leave anything to them. I reply
-whenever I am available without any intentional delays.

+You can find everything about the plugin on the [Wiki](https://github.com/NEZNAMY/TAB/wiki). This includes a detailed description
+of all features, as well as information regarding compatibility or limitations of each feature.  
 
 # Issues
-The [Issues](https://github.com/NEZNAMY/TAB/issues) section is **only** available for cases included in templates.
-In other words, they **are not available for**:  
-* **Support** - support is provided on discord for buyers, where roles are given to verified users
-allowing us to know who bought it and who didn't. It also serves as a much faster way of communication.
-* **Feature requests** - closed indefinitely.
-  
-**If you're a customer, please use discord for reporting bugs, especially if you aren't good at making bug reports. 
-You will be provided with a much faster and higher quality service.**
+The [Issues](https://github.com/NEZNAMY/TAB/issues) section is an issue tracker for all the kind of problems covered in issue templates.
+Please refrain from attempting to use it to receive help with your server, such issues will be closed immediately.  
+When opening an issue, provide as much information as possible. The difference between a bug getting fixed in 1 week vs 1 hour
+is in quality of the report. Bug reports where steps to reproduce are "idk" have no value and will not help to get the bug fixed at all.

+# Provided services
+The plugin is being used by a large amount of servers, which also means the demand for my attention is high. Unfortunately, 
+I am no longer able to keep up with the demand since I don't want to dedicate my whole existence to a free plugin. 
+In order to provide the best quality of all provided services, the amount of services provided may vary over time. 
+Here is the full list of potential services and their status:
+
+| Service type                  | Availability |
+|-------------------------------|--------------|
+| Updates for new MC versions   | ✔            |
+| Bug fixes                     | ✔            |
+| Wiki updates<sup>1</sup>      | ✔            |
+| Feature requests              | ❌            |
+| Customer support<sup>2</sup>  | ✔            |
+| Free user support<sup>3</sup> | ❌*           |
+| Optimization<sup>4</sup>      | ✔            |
+
+<sup>1</sup> - Adding new examples, guides and other kind of useful information people ask about.  
+<sup>2</sup> - Unrestricted assistance with the plugin for those, who bought a copy of the plugin when it was purchasable.  
+<sup>3</sup> - Unlimited access to my free time for everyone in the world.  
+<sup>4</sup> - Improving plugin's performance while not losing out on any features. This was done 
+proactively a lot in the past, so there isn't much to do anymore, only if someone actually finds and reports something.  
+  
+*Instead, you can use [this fresh new community discord](https://discord.gg/YPqXt63YQj) made by a nice person who will provide this service.

-/**
- * Scoreboard implementation for Bukkit, which uses packets
- * to send scoreboards. While md_5 keeps saying that you don't
- * need packets for scoreboards in every single spigot update,
- * this is not true. It may seem that way at first, but after
- * investigating, fatal problems are found:<p>
- * #1 - Limitations on legacy versions are forced in the API.
- *      While this may not seem like a problem, it enforces those
- *      limits even for 1.13+ players (if using ViaVersion).<p>
- * #2 - Modern versions no longer have any limits, but md_5
- *      decided to add some random limits for absolutely no reason
- *      at all. Scoreboard title received a random 128 characters
- *      limit including color codes. Together with the almighty bukkit
- *      RGB format using 14 characters for 1 color code, this makes
- *      gradients just impossible to use. Team prefix/suffix also
- *      received a 64 characters limit (excluding color codes at least),
- *      however that might not be enough for displaying a line of text
- *      in sidebar, which would require splitting the text into prefix
- *      and suffix, which is just begging for bugs to be introduced.<p>
- * #3 - Other plugins can decide to put players into their own
- *      scoreboard, automatically destroying all visuals made by the
- *      plugin. They might also put all players into the same scoreboard,
