-The recommended way to use `tracexec` is to create an alias with your favorite options in your bashrc:
+## Profile
 
-```bash
-alias tracex='tracexec log --show-cmdline --show-interpreter --show-children --show-filename --'
-alias txtui='tracexec tui -t --'
-# Now you can use
-tracex <command>
-txtui <command>
-```
+`tracexec` can be configured with a profile file. The profile file is a toml file that can be used to set fallback options.
+
+The profile file should be placed at `$XDG_CONFIG_HOME/tracexec/` or `$HOME/.config/tracexec/` and named `config.toml`.
+
+A template profile file can be found at https://github.com/kxxt/tracexec/blob/main/config.toml
+
+As a warning, the profile format is not stable yet and may change in the future. You may need to update your profile file when upgrading tracexec.
