+# Config
+
+The Rex configuration is as a json object in a file that Rex is pointed to as a commandline argument.
+
+In that file's json object, there is a field named "config", whose 
+properties define the configuration of Rex.
+
+There are currently 4 parameters that can be configured in the configuration file:
+
+1. `project_root`: The root directory of the project.
+2. `units_path`: The path to the units Library.
+3. `logs_path`: The path to the logs directory.
+4. `config_version`: The version of the configuration file.
+
+## Example
+
+```json
+{
+  "config": {
+    "project_root": "/home/user/project",
+    "units_path": "/home/user/project/units",
+    "logs_path": "/home/user/project/logs",
+    "config_version": 1
+  }
+}
+```
+
+There are some things to be aware of when setting the configuration file:
+
+1. The configuration file must be a valid json object.
+2. The configuration file must have a field named "config", whose properties define the configuration of Rex.
+3. All values for paths in this file are relative to the `project_root` path.
+4. The `logs_path` location will be created if it does not exist when Rex begins to execute.
