+## System Data
+
+System data is anything in the following locations:
+- `/Library`
+- `/System`
+- `~Library`
+- `/usr`
+- `.hidden_files`
+
+## Memory
+
+- Physical Memory - Total system memory
+- Memory Used
+    - App Memory - Memory used for apps
+    - Wired Memory - System memory
+    - Compressed - Memory used by apps, but compressed as it is not immediately needed
+- Cached Files - Files saved in memory for faster launching
+- Swap Used - Memory stored in the SSD
+
+### Memory Pressure
+
+A measurement of how well macOS is managing the available memory.
+- Green/Low: Normal function; No tricks needed.
+- Yellow/Medium: There is not enough memory as-is, so macOS is actively compressing and decompressing memory as needed.
+- Red/High: Aside from compression, macOS is using the swap heavily.
+
