-A modern implementation of the [BUGS](https://en.wikipedia.org/wiki/WinBUGS) probabilistic programming language in Julia. 
+**JuliaBUGS.jl** is a modern, high-performance implementation of the [BUGS](https://en.wikipedia.org/wiki/WinBUGS) probabilistic programming language in [Julia](https://julialang.org/). It brings the familiar BUGS modelling syntax into the Julia ecosystem, enabling Bayesian inference with speed, flexibility, and seamless integration with the scientific computing ecosystem in Julia.
 
-For a working example, follow this [link](https://turinglang.org/JuliaBUGS.jl/stable/example).

+## Why JuliaBUGS?
 
-See also, [JAGS](https://sourceforge.net/p/mcmc-jags/code-0/ci/default/tree/) and [Nimble](https://r-nimble.org/). 
+-   **BUGS syntax** — write models using standard BUGS notation.
+    
+-   **Julia performance** — leverage Julia’s speed and just-in-time (JIT) compilation.
+    
+-   **Interoperability with Julia ecosystem** — works smoothly with MCMC algrorithms from [Turing.jl](https://turinglang.org/) and the broader Julia PPL ecosystem.   
+
+---
+
+## Quick Start
+
+A simple example model:
+
+```julia
+using JuliaBUGS, Random, AbstractMCMC
+
+model = JuliaBUGS.@bugs"""
+model {
+  for (i in 1:N) {
+    y[i] ~ dnorm(mu, tau)
+  }
+  mu ~ dnorm(0, 0.001)
+  tau ~ dgamma(0.1, 0.1)
+}
+"""
+
+posterior = compile(model, (; N = 10, y = randn(10)))
+
+chain = AbstractMCMC.sample(rng, posterior, JuliaBUGS.IndependentMH(), 1000)
+```
+
+For a complete walkthrough, see the [example](https://turinglang.org/JuliaBUGS.jl/stable/example).
