 # open
 
-A Rust reimplementation of `xdg-open` command. It's written to be quickly and easily customizable, features separate local and global configs, and a zero-operand command allowing the user to specify how files should be opened differently, and for opening a project, etc.
+An opinionated, friendly alternative to `xdg-open` focused on opening files from a
+terminal. Easily understandable and configurable with a simple toml file.
 
-For example, for
-
-```ini
-[open]
-# zero-operand command
-command = atom .
-# use $EDITOR to edit files without specified commands?
-use_editor = true
-
-[.md]
-command = typora
-
-[.rs]
-command = atom
-
-[filename:.gitignore]
-command = vim
-shell = true
-```
-
-I can use `open` to open the directory in Atom, or I could use `open src/main.rs` to open `main.rs` in Atom, and I can specify these on a per-project basis.
-
-For directories with a local config, any missing values will be filled in by the global config (`~/.config/open.conf`), which means local configs can be shorter.
