@@ -127,6 +127,47 @@ To run an example or the assigment, simply run the command, e.g. **./shapes.exe*
 in the same directory. (Note: it is important that you run the executables in the
 **window_build** directory.)
 
+## Linux
+
+For Linux you need to first install the packages
+
+```bash
+sudo apt install libsdl2-dev
+sudo apt install libsdl2-image-dev
+sudo apt install libsdl2-ttf-dev
+sudo apt install libfreetype6-dev
+sudo apt install libtiff-dev
+sudo apt install libbz2-dev
+```
+
+To make it slightly easier to build both the examples and the assigment itself a Makefile is provided:
+
+- **Makefile_linux**
+
+To build run the command:
+
+```bash
+make -f Makefile_linux
+```
+
+in the root directory. This will build the resulting 
+executables in the directory **build**. **build** will
+contain the example executables:
+
+```bash
+./build/shapes
+./build/splat
+./build/sprite
+```
+
+and for the assigment:
+
+```bash
+./build/assignment
+```
+
+To run an example or the assigment, simply run the executable from the root directory, e.g. **./build/shapes**.
