 ## Tcl compilation
 Extract the Tcl sources and then go to the unix folder:
 
-`cd <extracted-folder>/unix`  
-`./configure --prefix=/usr/local/opt/tcl-tk`  
-`make`
-`make install`  
+```
+cd <extracted-folder>/unix
+./configure --prefix=/usr/local/opt/tcl-tk  
+make
+make install
+```
 
 ## Tk compilation
 Same procedure as Tcl, but we need to specificy the Tcl and X libraries paths. XQuartz is installed on
 /opt/X11 , so we do:  
 
-`cd <extracted-folder>/unix`  
-`./configure --prefix=/usr/local/opt/tcl-tk \
+```
+cd <extracted-folder>/unix
+./configure --prefix=/usr/local/opt/tcl-tk \
 --with-tcl=/usr/local/opt/tcl-tk/lib --with-x \
---x-includes=/opt/X11/include --x-libraries=/opt/X11/lib`  
-`make`  
-`make install`  
+--x-includes=/opt/X11/include --x-libraries=/opt/X11/lib  
+make
+make install  
+```
 
 ## xschem compilation
 Besides referencing the X libraries, we need to also point to the Tcl/Tk installation path. Let's use a recent
 xschem repository and install it on ~/xschem-macos (adapt this to your username):  
 
-`git clone https://github.com/StefanSchippers/xschem.git`  
-`cd xschem`  
-`./configure --prefix=/Users/$(whoami)/xschem-macos`  
+```
+git clone https://github.com/StefanSchippers/xschem.git  
+cd xschem  
+./configure --prefix=/Users/$(whoami)/xschem-macos
+```
 
 Before building the application, we need to adjust `Makefile.conf` because the current configure
 script doesn't support custom flags. So we need to replace the CFLAGS and LDFLAGS variables in that file
 as below:  
-`CFLAGS=-I/opt/X11/include -I/opt/X11/include/cairo \
+
+```
+CFLAGS=-I/opt/X11/include -I/opt/X11/include/cairo \
 -I/usr/local/opt/tcl-tk/include -O2
 LDFLAGS=-L/opt/X11/lib -L/usr/local/opt/tcl-tk/lib -lm -lcairo \
--lX11 -lXrender -lxcb -lxcb-render -lX11-xcb -lXpm -ltcl8.6 -ltk8.6`  
+-lX11 -lXrender -lxcb -lxcb-render -lX11-xcb -lXpm -ltcl8.6 -ltk8.6
+```
 
 Finally, we compile and install the application.  
 
-`make
-make install`  
+```
+make
+make install
+```
 
 The application will be placed in /Users/$(whoami)/xschem-macos/bin and can be started with
 ./xschem in that folder.
