 # Build it
 
-*lead* uses [clang](http://clang.llvm.org/) as compiler, [g++](https://gcc.gnu.org/) as linker and [make](https://www.gnu.org/software/make/) as build-tool. 
+*lead* uses [make](https://www.gnu.org/software/make/) as the build-tool, but the makefile is generated with [qmake](https://wiki.qt.io/Qmake).
+
+*qmake* offers flexibility in compiler and linker choice, but [gcc](https://gcc.gnu.org/) and [g++](https://gcc.gnu.org/) have been proven to work.
 
 To build *lead* open a terminal in the root folder of the repository and:
 
-    $ make
+    $ qmake && make
+
+or alternatively (depending on distribution):
+
+    $ qmake-qt5 && make
 
 ### Dependencies
+
 - Qt5Widgets 
 - Qt5Gui 
 - Qt5Core
 
+Instructions on installing the dependencies:
+|OS|Command|
+|---|---|
+|Ubuntu 20.04|`$ sudo apt install -y qt5-default qt5-qmake`|
+|Fedora 34|`$ sudo dnf install -y qmake-qt5-devel`|
