 ### Contents ###
 
-This is the fortran source code and GUI of TrimSP Monte-Carlo simulations. 
+This repository contains the [Fortran] source code and an accompanying
+graphical user interface ([GUI]) for TrimSP -
+an application for performing [Monte Carlo] simulations of ion implantation. 
 
-* This code is specifically tuned to simulate implantation of low energy projectiles in materials.
-* The code is maintained by the Low Energy Muons group at PSI. 
-* The GUI is written in Node.js, JavaScript and Electron. 
-* The binary (statically linked) from the fortran code is also included.
-* RPM and DEB packages are also included

 ### Installation ###
+
 ###### Fortran code compilation ######
 
-Install gfortran compiler, then:
+Install the `gfortran` compiler, then:
 
-    cd trimsp/fortran
-	make
-    make install
+```bash
+cd trimsp/fortran
+make
+make install
+```
     
-This will install the `trimspNL` in `/usr/local/bin`, but can be moved to any other directory in your `PATH`.
+This will install the `trimspNL` binary in `/usr/local/bin`,
+but it can be moved to any other directory in your `PATH`.
 
 ###### Running the GUI ######
 
-Install Node.js (nodejs, nodejs-libs and npm), then
+Install [Node.js] (`nodejs`, `nodejs-libs` and `npm`),
+then run:
 
-    cd trimsp
-    npm install
-    npm start
+```bash
+cd trimsp
+npm install
+npm start
+```
 
-You do not need to run `npm install` every time. Next time you can simply run `npm start` only. 
+Note: you do not need to run `npm install` every time.
+Next time you can simply run `npm start` only.
