+Installation:
+-------------
+Step 1: Configure
+./configure --prefix=<installation_path> or ./configure to install the library
+in the default directory (default prefix: /usr/local/lib)
+
+Step 2: Build
+Enter the libgliar source directory and run:
+make
+
+Step 3: Install
+Inside the source directory type:
+make install (or sudo make install if you used the default prefix)
+
+Uninstall:
+----------
+Enter the source directory and type:
+make uninstall (or sudo make uninstall if you used the default prefix)
