+# How to build
+I wish I could say all you need is Qt and Firebird library... But it's not true, he-he... Unfortunately ACE Lab (R) uses too old Firebird 2.x engine for their database and this engine is 32-bit only. This means Firebird library must be 32-bit too. And this also means your Qt application also must be 32-bit. And this also means you have to use old 32-bit MinGW available in Qt5 only. Yes, you can forget about Qt6. I recommend Qt 5.15.2 + MinGW 8.1 32-bit.
+
+## Requirements
+1. Last available Qt5 + MinGW 32-bit. Don't forget about Qt sources, you'll need them too.
+2. Firebird 2.x sources, for example from [there](https://www.firebirdsql.org/en/firebird-2-5-4/#Win32). All you need is `Firebird-2.5.4.26856_0_Win32.exe`, just install it with default options.
+3. QHexEdit2 widget from [there](https://github.com/simsys/qhexedit2).
+
+## Adding Firebird support to Qt
+To add Firebird (IBASE) support to Qt use `make-qt-ibase.cmd` command file. Do not forget to run this file from MinGW 32-bit environment.
+
+## QHexEdit2 widget compilation
+To compile QHexEdit2 widget type following commands from MinGW 32-bit environment:
+```
+qmake qhexedit.pro
+mingw32-make
+```
+
+## Known troubleshooting
+If you see error message - "driver not loaded" - try to copy `fbclient.dll` from the Firebird binaries to the folder of your application.
