+<h1>The Ibu programming language</h1>

+[Changelog]() |
+[Docs](docs/docs.md) |

+[![CI](https://github.com/v420v/ibu/actions/workflows/ci.yml/badge.svg)](https://github.com/v420v/ibu/actions/workflows/ci.yml)
+
+- No strict type checker
+- No C-like pointer arithmetic
+- No function-like macros
+- No `break`, `continue` stmt. Use `goto`
+- Allows `13 <= age < 20` instead of `13 <= age && age < 20`
+- Variable length args `func(...)` can be accessed with built-in variables `argc i64` and `argv *i64`
+- The compiler is written in itself
+- Default args don't have to be on the end (WIP)
+
+```go
+#include "std/header.ibu"
+
+func main() i32 {
+    let age i32 = 19;
+
+    if 13 <= age < 20 {
+        printf("Teen-ager\n");
+    }
+
+    return 0;
+}
+```
+
+## Installing the Language
+```zsh
+$ git clone git@github.com:v420v/ibu.git
+$ cd ibu
+$ make up
+$ make ibulang
+$ make init
+```
+
+## How to Use the Compiler
+A simple example compile and run hello world
+```zsh
+$ ./ibuc main.ibu | as - -o main.o
+$ as -o lib/runtime.o lib/runtime.s
+$ ./ibuc lib/linux-syscall/linux-syscall.ibu | as - -o lib/linux-syscall.o
+$ ./ibuc lib/std/std.ibu                     | as - -o lib/std.o
+$ ld -o main main.o lib/runtime.o lib/linux-syscall.o lib/std.o
+$ ./main
+```
