+# High Ground
+
+High Ground is a programming language based on Ground.
+
+It is the reference language designed to teach you how to build your own Ground-based language.
+
+## Compiling
+
+First, ensure CGround is installed on your system with `sudo make install`. Then, compile with
+
+```
+g++ src/main.cpp -o hg -lgroundvm
+```
+
+## Usage
+
+High Ground files use the `.hg` extension. Run files as you would with any other interpreted language.
+
+## Using High Ground
+
+### Types
+
+* `int`: Ground int (64 bit integer) eg 3, 7, 31432
+* `double`: Ground double (Double precision floating point) eg 3.141, 2.7
+* `string`: Ground string (char*) eg "Hello, World"
+* `char`: Ground char (char) eg 'a'
+* `bool`: Ground bool (either true or false)
+
+### Printing
+
+Prefix an expression with `puts` to print it to the console.
+
+```
+puts "Hello, world!"
+puts 3.141
+puts 7
+puts 'a'
+puts true
+```
+
+### Math
+
+Add numbers with `+` (more operations coming soon)
+
+```
+puts 1 + 1
+puts 3.14 + 2.7
+puts 532 + 314 + 89432
+```
