-Adds VBA language support to VSCode via LSP compliant Language Server.
+# VBA Pro Extension for VScode
+
+Provides Visual Basic for Applications (VBA) language support in Visual Studio Code using a Language Server Protocol (LSP) compliant backend. We all know that VBA is a dinosaur from the '90s, but it doesn't have to feel like one.

+
+### Syntax Highlighting
+
+The most complete and bug-free TextMate grammar for VBA out there.
+
+### Semantic Highlighting
+
+TextMate does a great job with syntax highlighting but there are some things it can't know. Semantic highlighting is resolved by the language server and helps support where context is required.
+
+### Folding Ranges
+
+Folding ranges help organise code, collapsing things out of the way when you don't need to be looking at them.
+
+### Code Snippets
+
+A small but growing collection of highly useful code snippets. The idea is to keep these to a "rememberable" level, but if there's something you use all the time and you think it's missing, I'd love to hear from you.
+
+### Document Symbols
+
+Document Symbols allow you to view a structured outline of your code in the VSCode Outline view and breadcrumbs. These make it easy to understand and navigate files.
+
+### Document Diagnostics
+
+Displays warnings and errors in the Problems panel, as well as underlining the relevant sections in your code. Only a few diagnostics have been implemented to date, however these will be fleshed out over time.
+
+## Document Formatting
+
+Whole of document formatting is supported with `Shift+Alt+F`. Keeps your code properly indented and easy to read. Also supports half indentation for conditional compilation logic and the complexities that come with it.
 
-\*Currently full document `Shift+Alt+F` formatting only.
+```vba
+#If VBA7 then
+  Public Property Get Foo() As LongPtr
+#Else
+  Public Property Get Foo() As Long
+#End If
+	Foo = 0
+End Property
+```
