-## Project Structure
+## Global Data Block Support
+
+The plugin automatically scans for `.db` files in the workspace and provides auto-completion for global data blocks and their members.
+
+### How it works
+
+1. **Workspace Scanning**: When opening a `.scl` file, the plugin scans the project for `.db` files
+2. **DB Parsing**: Parses `DATA_BLOCK` definitions and extracts members from `VAR` sections
+3. **Auto-completion**: Provides smart completion for DB names and members
+
+### Usage
+
+- Type a space or `#` to trigger completion - global DB names appear alongside local variables
+- Type `"` followed by a DB name to get member completions
+- Access nested members: `"MyDB".member.submember`
+
+### Example
+
+```scl
+// Access global DB members
+"HmiData".units
+"Parameter".machine.unit100.paramTimeStampApplied
+
+// Inside FB call parameter
+#instParameterManager(hmiInterface:="HmiData".units, ...)
+```
