+# Using as crate
+
+This article describes how to use the client as rust crate
+
+## Installation
+
+To use exact version:
+
+```toml
+[dependencies.bRAC]
+git = "https://github.com/MeexReay/bRAC"
+tag = "0.1.2+2.0"
+default-features = false
+```
+
+To use with latest changes:
+
+```toml
+[dependencies.bRAC]
+git = "https://github.com/MeexReay/bRAC"
+default-features = false
+```
+
+`default-features = false` here removes GTK4 gui from installation.
+
+## Usage
+
+As the code structure was changed like about gazillion times, 
+you need to explore it yourself, if you are using an old version. 
+Here is example of usage on commit [80e7b8c](https://github.com/MeexReay/bRAC/commit/80e7b8c50642f9b76be06980305ed03253858d0c)
+
+```rust
+use bRAC::proto::*;
+use std::error::Error;
+
+fn main() -> Result<(), Box<dyn Error>> {
+    let mut conn = connect("rac://meex.lol", None)?; // read docs/url.md
+
+    send_message(&mut conn, "<dude> hi RAC-loving kikes!")?;
+    register_user(&mut conn, "dude", "password")?;
+    send_message_auth(&mut conn, "dude", "password", "my auth message")?;
+    send_message_spoof_auth(&mut conn, "<dude> this message totally fucks auth system")?;
+
+    let (mut all_messages, last_size) = read_messages(&mut conn, 10, 0, false)?.unwrap(); // limits with 10 messages
+
+    /* imagine that new messages were written here */
+
+    let (mut new_messages, last_size) = read_messages(&mut conn, 10, last_size, true)?.unwrap(); // chunked reading!
+
+    all_messages.append(&mut new_messages);
+
+    println!("all_messages: {all_messages:?}. last_size: {last_size}");
+
+    Ok(())
+}
+```
