 ### Quick Installation (Recommended)
 
-The installation script automatically detects your CPU and configures optimal build settings:
+Step 0: Create and activate a conda environment (recommended):
 
 ```bash
-# Simple one-command installation (auto-detects CPU)
-./install.sh
+conda create -n kt-kernel python=3.11 -y
+conda activate kt-kernel
 ```
 
-The installation script will:
+You can now install in two clear steps using the same script.
+
+Option A: Two-step (explicit)
+
+```bash
+# 1) Install system prerequisites (cmake, hwloc, pkg-config)
+./install.sh deps
+
+# 2) Build and install kt-kernel (auto-detects CPU)
+#    By default, the script cleans the local ./build directory before compiling.
+./install.sh build
+```
+
+Option B: One-step (deps + build)
+
+```bash
+# Simple one-command installation
+./install.sh            # same as: ./install.sh all
+# Skip deps step if you already installed them
+./install.sh all --skip-deps
+```

+The install script will:
 - Auto-detect CPU capabilities (AMX support)
-- Install `cmake` via conda (for the latest version)
+- Install `cmake` via conda (if available)
 - Install system dependencies (`libhwloc-dev`, `pkg-config`) based on your OS
