+# Banks & Patterns
+
+Cagire organizes all your patterns and data following a strict hierarchy:
+
+- **Projects** contain **Banks**.
+- **Banks** contain **Patterns**.
+- **Patterns** contain **Steps**.
+
+## Structure
+
+```
+Project
+└── 32 Banks
+    └── 32 Patterns (per bank)
+        └── 128 Steps (per pattern)
+```
+
+A single project gives you 32 banks, each holding 32 patterns. You get 1024 patterns in each project, ~131.000 steps.
+
+## Patterns
+
+Each pattern is an independent sequence of steps with its own properties:
+
+| Property | Description | Default |
+|----------|-------------|---------|
+| Length | Steps before the pattern loops (`1`-`128`) | `16` |
+| Speed | Playback rate (`1/8x` to `8x`) | `1x` |
+| Quantization | When the pattern launches | `Bar` |
+| Sync Mode | Reset or Phase-Lock on re-trigger | `Reset` |
+
+Press `e` in the patterns view to edit these settings.
+
+## Patterns View
+
+Access the patterns view with `Ctrl+Up` from the sequencer. The view shows all banks and patterns in a grid. Indicators show pattern state:
+
+- `>` Currently playing
+- `+` Staged to play
+- `-` Staged to stop
+
