+# catsh
+
+A small (ish) shell written in ( \*hopefully ) modern C++.
+
+Made while doing the codecrafters' shell implementation challenge -- but let's see I'll add stuff that I find interesting.
+Given it's at ~1000 LOC the goal is still to keep it as small as possible, as part of that
+
+- Almost no error handling on POSIX apis or otherwise
+- Linux only
+- Edge cases are intended to be unhandled wherever they are
+- focus on "terse" modern cpp code and practices, even if they are not the most efficient
+
+what we DO have is
+
+- no external dependencies ( not even GNU readline ), except POSIX and C++ standard library
+- support for pipelines, redirection, and background processes
+
+## Running
+
+`make` wrapper over `cmake`
+
+```sh
+make build
+make run
+make clean
