 # Perfmon
 Perfmon is a TUI that shows essential performance monitoring commands in one place. It uses a tabbed approach for showing the results, making it quick to find stats in one place.
 
+
+![Perfmon Screenshot](assets/screenshot.png)
+
 ## Features
 - Tabbed command output with keyboard navigation
 - Summary strip with sparklines (load, CPU, memory, network)
 - Disabled tab detection with install hints
 - Configurable tabs via TOML
 - Theme toggle (`t`)

 - Memory: `free -m` (Linux)
 - Net: `/proc/net/dev` (Linux) or `netstat -ib` (macOS)
 
+If no configuration file is found, Perfmon falls back to a sensible set of defaults (uptime, vmstat, mpstat, iostat, free, sar, top, neofetch).
+
 If a command is missing, the tab is disabled and a hint is shown.
 
-## Config
-Perfmon can load a custom tab list from a TOML file. Search order:
-1. `PERFMON_CONFIG` env var (full path)
-2. `$XDG_CONFIG_HOME/perfmon/config.toml` (or `~/.config/perfmon/config.toml`)
-3. `./perfmon.toml`
 
-Example `perfmon.toml`:
-```toml
-[[tab]]
-title = "uptime"
-cmd = ["uptime"]
+## Development
+
+See [CONTRIBUTING.md](CONTRIBUTING.md) for instructions on how to set up your development environment and contribute to the project.
