 #### Building the project
 In the project directory, run the following commands: `./autogen.sh` then run `./configure`. If autogen complains that it couldn't find a directory named "m4", run: `mkdir m4` and then `./autogen.sh`.
 
+- note: Running configure with a prefix like: `./configure --prefix=/some/custom/path` will cause `make install` to install the library to that directory instead of the default one.
+
 At this point we should be able to build the project by running:
 ```
 make
 ```
+By default `make` builds a shared library. To build a static library, run make with "static" flag on: `make CFLAGS=-static`. 
+
+
+Installing the library:
+```
+make install
+```
+
 The tests can be run by:
 ```
 make check
 ```
+#### Compiling and linking a simple program
+- hello.c
+```c
+#include <stdio.h>
+#include <array.h>
+
+int main(int argc, char **argv) {
+ Array *ar = array_new();
+ array_add(ar, "Hello World!\n");
+ 
+ printf("%s", (char*) array_get(ar, 0));
+ 
+ return 0;
+}
+```
+We can now build and staticly link the library to our program:
+```
+gcc hello.c -I/path/to/library/include/ -static -L/path/to/library/lib/ -lcollectc -o hello
+```
