 Would you rather re-define the same functions or types over and over as you work with different binaries?
 
-## Usage (IDA Pro, 7.2+ recommended)
+## Usage (IDA Pro 8+)
+1. Copy `IDA.til` to `til` folder inside IDA application directory.
+2. In IDA Pro, open `Type Libraries` window via `View > Open subviews > Type libraries` or press `Shift + F11`.
+3. Right-click the type list and select `Load type library...`.
+4. Select `IDA` and click `OK` button.

+```bash
+tilib -c -hIDA.h IDA.til -D__EA64__ -P

+
+## Usage (IDA Pro 7)
 Go to `File > Load file > Parse C header file` then choose `IDA.h` to import everything at once.
 
 Or, run this IDA command: `idaapi.idc_parse_types("/path/to/IDAObjcTypes/IDA.h", idc.PT_FILE)`
