 -----------------------
 
 Install dependencies. Here's an example for Debian/Ubuntu:
-$ apt-get install build-essential libirrlicht-dev cmake libbz2-dev libpng12-dev libjpeg8-dev libxxf86vm-dev libgl1-mesa-dev libsqlite3-dev
+$ sudo apt install build-essential libirrlicht-dev cmake libbz2-dev libpng-dev libjpeg8-dev libxxf86vm-dev libgl1-mesa-dev libsqlite3-dev git
 
 Download source, extract (this is the URL to the latest of source repository, which might not work at all times):
-$ wget https://github.com/celeron55/minetest/tarball/master -O master.tar.gz
-$ tar xf master.tar.gz
-$ cd celeron55-minetest-286edd4 (or similar)
+$ git clone https://git.minetest.land/oerkki/minetest.git
+$ cd minetest
+or (without git):
+$ wget https://git.minetest.land/oerkki/minetest/archive/stable-0.3.tar.gz -O minetest.tar.gz
+$ tar xf minetest.tar.gz
+$ cd minetest
 
 Build a version that runs directly from the source directory:
 $ cmake . -DRUN_IN_PLACE=1
-$ make -j2
+$ make -j($nproc)
 
 Run it:
-$ cd bin
-$ ./minetest
+$ ./bin/minetest
 
 - Use cmake . -LH to see all CMake options and their current state
 - If you want to install it system-wide (or are making a distribution package), you will want to use -DRUN_IN_PLACE=0
