+## Wat?
+This is a Telegram-bot that collects all the stickers sent to it in one (almost) infinite pack. No more, no less.
+
+**Benefits:**
+- Does not require creation of a set with a unique URL and/or name;
+- Indeed (almost) unlimited pack size;
+- Keeps stickers belonging to their original sets;
+- Fully support the standard functionality of Telegram stickers (for example "add to favorites");
+- Avaliable anywhere in Telegram by typing `@MyPackBot ` in the input field;
+- Supports filtering of results by emoji: `@MyPackBot 😀`;
+- Fast as f\*\*\*king Sonic;
+- Worked with uploadable WebP stickers;
+- Worked with blocked by rightholders sets (but this is not exact);
+
+**Disadvantages:**
+- Requires type `@MyPackBot ` in the input field;
+- Availability depends on the internet connection and bot uptime;
+- Supports search/filtering only for first emoji associated with sticker;
+- Does not support synchronization of the updated original set contents with the saved set contents in the bot.
+
+## Why?
+Because Telegram native tools for managing stickers are somewhat limited:
+- User can have only **up to 200 active stickers sets**;
+- In one set can be uploaded **up to 120 stickers**;
+- User can have only **up to 5 favorites stickers**;
+
+Having done simple mathematical calculations, we can assume that the **maximum user capacity** (when he has the maximum number of sets, each of which contains the maximum number of stickers) **is equal 24,000 stickers**.
+
+But, as usual, there are problems:
+- **Most of the sets are incomplete** and contain less than 120 stickers (sometimes - only 1-3 stickers on whole set);
+- **Some sets contains junk, duplicated and promotional stickers**;
+- **Sometimes user want use own stickers** by uploading WebP files, but without creating new sticker set;
+- Anyway, **user just want have as many stickers as he want**;
+
+To solve these problems, this bot was designed.
+
+## How?
+### tl;dr
+- Telegram API [supports stickers as results](https://core.telegram.org/bots/api#inlinequeryresultcachedsticker) in inline query;
+- Telegram API allows to use someone else's FileID for results;
+- It is not necessary to [create a new set](https://core.telegram.org/bots/api#createnewstickerset) using Telegram, since it only "references" existing files;
+- Bot saves only [user](https://core.telegram.org/bots/api#user) info, [sticker and name of his set](https://core.telegram.org/bots/api#sticker) in the database if user upload custom sticker or send/forward already existing;
+- Database architecture allows to filter keys by user ID and sort them by set name and emoji value;
+- When requesting inline query, bot simply create results from filtered database keys;
+- ???????
+- PROFIT!!1

+I'm too lazy to write, so just check the source code for the comments. 👀
+
+### Dependencies
+Bot uses the following dependencies:
+- Written on [Go](https://github.com/golang/go) language, because I <3 Go;
+- I ventured to migrate to my own [telegram](https://github.com/toby3d/telegram) package to win in convenience and productivity;
+- I use [dlog](https://github.com/kirillDanshin/dlog) for debugging without spamming on production server by use only one build flag;
+- Data of users and stickers save thanks to [BuntDB](https://github.com/tidwall/buntdb);
