-## 🔧 Key Features
+## Key Features
 
 - **Dynamic Config Reloads** — Upstreams can be updated live via API, no restart required.
-- **TLS Termination** — Built-in OpenSSL support.
+- **Yes loading of certificates** — Auto load certificates from a folder, without a restart.
-    - **Automatic load of certificates** — Automatically reads and loads certificates from a folder, without a restart.
+- **Let’s Encrypt Certificates** — Yes ordering and renewal of SSL/TLS certificates via the HTTP-01 challenge
 - **Upstreams TLS detection** — Aralez will automatically detect if upstreams uses secure connection.
-- **Built in rate limiter** — Limit requests to server, by setting up upper limit for requests per seconds, per virtualhost.
+- **Built in rate limiter** — Globar or route limit requests to upstreams.
-    - **Global rate limiter** — Set rate limit for all virtualhosts.
-    - **Per path rate limiter** — Set rate limit for specific paths. Path limits will override global limits.
 - **Authentication** — Supports Basic Auth, API tokens, and JWT verification.
     - **Basic Auth**
     - **API Key** via `x-api-key` header
     - **JWT Auth**, with tokens issued by Aralez itself via `/jwt` API
-        - ⬇️ See below for examples and implementation details.
+    - **Forward Auth**, Sends requests to an authentication server.
-- **Load Balancing Strategies**
+- **Load Balancing** Round-robin, health checks, optional sticky sessions.
-    - Round-robin
-    - Failover with health checks
-    - Sticky sessions via cookies
-- **Unified Port** — Serve HTTP and WebSocket traffic over the same connection.
 - **Built in file server** — Build in minimalistic file server for serving static files, should be added as upstreams for public access.
-- **Memory Safe** — Created purely on Rust.
+- **Upstream Providers:**
-- **High Performance** — Built with [Pingora](https://github.com/cloudflare/pingora) and tokio for async I/O.
-
-## 🌍 Highlights
-
-- ⚙️ **Upstream Providers:**
     - `file` Upstreams are declared in config file.
     - `consul` Upstreams are dynamically updated from Hashicorp Consul.
-- 🔁 **Hot Reloading:** Modify upstreams on the fly via `upstreams.yaml` — no restart needed.
+    - `kubernetes` Upstreams are dynamically updated from kubernetes api server.
-- 🔮 **Automatic WebSocket Support:** Zero config — connection upgrades are handled seamlessly.
+- **Yes WebSocket Support:** WS connection upgrades are handled automatically.
-- 🔮 **Automatic GRPC Support:** Zero config, Requires `ssl` to proxy, gRPC handled seamlessly.
+- **Yes gRPC Support:** gRPC detected and handled automatically.
-- 🔮 **Upstreams Session Stickiness:** Enable/Disable Sticky sessions globally.
+- **Header Injection:** Global and per-route server/client headers injection.
-- 🔐 **TLS Termination:** Fully supports TLS for upstreams and downstreams.
+- **Remote Config Push:** Lightweight HTTP API to update configs from CI/CD or other systems.
-- 🛡️ **Built-in Authentication** Basic Auth, JWT, API key.
+- **Memory Safe** — 100% Rust.
-- 🧠 **Header Injection:** Global and per-route header configuration.
+- **High Performance** — Built with [Pingora](https://github.com/cloudflare/pingora) and tokio for async I/O.
-- 🧪 **Health Checks:** Pluggable health check methods for upstreams.
-- 🛰️ **Remote Config Push:** Lightweight HTTP API to update configs from CI/CD or other systems.

+## About binaries
+
+**glibc** builds are in general faster, but have few, basic, Glibc dependencies:
+
+**musl** builds are 100% portable, static compiled binaries and have zero system dependencies.
+In general musl builds have a little less performance.
+
+The most intensive tests shows 107k-110k requests per second on **Glibc** binaries against 97k-100k **Musl** ones.
+
+For running **Aralez** on very old hardware, CPUs prior Haswell, (launched before 2013) use `aralez-x86_64-compat-*.gz`
+For getting the best performance on newer hardware use `aralez-x86_64-*.gz`.
