+
+# Installation objectives
+
+Ideally, yes, if the installation script is well-designed, users should be able to simply type "zhankai" in their terminal to run the app after using the curl command. However, there are a few important considerations:
+
+1. Path addition: The installation script would need to add the zhankai executable to the user's PATH. This typically involves:
+   - Placing the executable in a standard location (e.g., /usr/local/bin on Unix-like systems)
+   - Or adding the installation directory to the user's PATH environment variable
+
+2. Shell configuration: If the PATH is modified, the script might need to update the user's shell configuration file (e.g., .bashrc, .zshrc) and prompt them to restart their terminal or source the updated configuration.
+
+3. Permissions: The script would need to ensure that the installed executable has the correct permissions to be run by the user.
+
+4. Multiple shells: If the user uses multiple shells, the script should ideally configure zhankai for all of them.
+
+5. System vs. user installation: The script should handle both system-wide installations (requiring sudo) and user-specific installations appropriately.
+
+6. Dependencies: If zhankai has any runtime dependencies, the script should check for and possibly install them.
+
+To ensure this smooth experience, the installation script should:
+
+1. Detect the user's environment (OS, shell, etc.)
+2. Install zhankai in an appropriate location
+3. Update PATH if necessary
+4. Set correct permissions
+5. Provide clear output about what it's doing and any next steps required
+
+With a well-implemented installation script, users should indeed be able to simply type "zhankai" to run the app immediately after installation. However, in some cases, they might need to open a new terminal window or source their updated shell configuration first.
+
+It's also good practice for the script to output instructions at the end, such as:
+
+```
+Installation complete! You can now run zhankai by typing 'zhankai' in your terminal.
+If it doesn't work immediately, try opening a new terminal window or running 'source ~/.bashrc' (or your appropriate shell config file).
+```
+
+This approach provides a smooth, user-friendly installation experience across different systems and shells.
