+# Snowcast
+
+## Description
+
+A music streaming server consisting of three programs: the server, the client controller, & the client listener.
+
+## Getting Started
+
+### Making the executables
+
+* Ensure you have gcc installed, as that is what the Makefile uses.
+* Run `make` in your terminal to make the 3 executables `./snowcast_server`, `./snowcast_control`, & `./snowcast_listener`!
+
+### Executing program
+
+Running the 3 executables without arguments will tell you the necessary arguments to get going.
+
+* To run the server, type in `./snowcast_server` into your terminal.
+* To run the controller, type `./snowcast_control` into your terminal.
+* To run the listener, type `./snowcast_listener` into your terminal.
+
+### Program Design
+
+I did not implement origonal design doc, due to random malloc errors with the autograder. I rewrote the server, with the the design...
+
+* A "select_thread" controls accepting new clients and responding to commands from clients. It redirects the logic to separate helper functions to send replies.
+* The station information is held by an array. Each station has a thread that broadcasts to the listeners every half-second (at half the rate per second). At the bottom of this half-second, the station file is read into a buffer and threads are created off of this buffer, waiting to be released. At the top of this half-second, the station thread then bradcasts a `cond` variable to start all threads that send the station.
+* The `users` pointer containing the user data (along with the separate stations pointer) has a mutex `users_mutex` that allows safe-thread write and deletion. This pointer is also dynamic, using realloc when more memory is needed. There are a few memory optimizations implemented (see `init_user(...)`).
+* The code is well documented, so many smaller design choices can be read there :)
