+#### Installation Directory
+
+The install script respects the following priority order for the installation path:
+
+1. `$OPENCODE_INSTALL_DIR` - Custom installation directory
+2. `$XDG_BIN_DIR` - XDG Base Directory Specification compliant path
+3. `$HOME/bin` - Standard user binary directory (if exists or can be created)
+4. `$HOME/.opencode/bin` - Default fallback
+
+```bash
+# Examples
+OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
+XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
+```
+
