 ### Compiling
 
-This program compiles like any other ordinary Go project, simply **run** `go build .` in the project directory.
+You need to have Go toolchain installed:
+```shell
+# Debian
+sudo apt install golang
+
+# Fedora
+sudo dnf install golang
+```
+
+Then, just **clone the repo** and run **`go build .`** to compile an executable.
