 Clone the repository in your chosen directory. In a new terminal:
 
-```
+```bash
 cd <your/path>
 git clone <repo-link>
 ```
 
 Clone the RTKLIB lib as a sub-module:
-```
+```bash
 git submodule update --init
 ```
 
 Create a directory to build all the source files:
-```
-$ mkdir build
-$ cd build
+```bash
+mkdir build
+cd build
 ```
 
 Compile the source files:
 
+```bash
+cmake ..
+make
+```
+
+Install the library:
+
+```bash
+make install
+```
+
+## Installation in local folder
+
+With the previous steps, the library will be stored in `CMAKE_PREFIX_PATH` that usually is `/usr/local`. If you want to install the library in a local folder (avoiding sudo permissions), you can add these lines in your `.bashrc` file:
+
+```bash
+export WOLF_PREFIX=/your/local/installation/path # To be substituted by your desired installation path
+export LD_LIBRARY_PATH=$WOLF_PREFIX/lib:$LD_LIBRARY_PATH
+export CMAKE_PREFIX_PATH=$WOLF_PREFIX:$CMAKE_PREFIX_PATH
+```
+
+And compile with:
+```bash
+cmake .. -DCMAKE_INSTALL_PREFIX=$WOLF_PREFIX
+make
+make install
 ```
-$ cmake ..
-$ make
-```
