+# Overview of processes in MOP3
+
+## What is a process?
+
+A process is a structure defined to represent an internal state of a user application's environment. This includes
+the necessary stacks, code, data and other resources. A process (usually) has it's own address, but in certain
+circumstances may share it with another process.
+
+## Only processes vs. processes-threads model
+
+### Overview
+
+MOP3 doesn't have a process-thread separation. Ususally in operating systems you'd have a "process", which consists
+of multiple worker threads. For eg. a single-threaded application is a process, which consists of one worker. In MOP3
+we do things a little differently. We only have processes, but some processes may work within the same pool of (generally speaking)
+"resources", such as a shared address space, shared memory allocations, mutexes and so on. An application then consists of
+not threads, but processes, which are loosely tied together via shared data.

+
+## Scheduling
+
+MOP3 uses a round-robin based scheduler. For now priorities are left unimplemented, ie. every processes has
+equal priority, but this may change in the future.
+
+A good explaination of round-robin scheduling can be found on the OSDev wiki: [the article](https://wiki.osdev.org/Scheduling_Algorithms#Round_Robin)
