 ## How to build and run examples
 
 The easiest way to start with Mongoose is to try to build and run examples.
-The required tools are: a C/C++ compiler, the `make` utility, and `git`.
+Follow the [Development Environment](/tutorials/tools) tutorial to setup your
-
+development environment: a C compiler, a `make` utility, and a `git` utility.
-You can follow these links for tutorials on how to install these tools on your platform of choice
+Start a terminal / command prompt and execute the following commands:
-
-- [GCC](http://mongoose.ws/tutorials/tools/#gcc), the GNU C/C++ compiler collection
-  - On Windows, you might want to use "[Build Tools for Visual Studio](https://visualstudio.microsoft.com/downloads)" instead
-- [GNU make](http://mongoose.ws/tutorials/tools/#gnu-make)
-- [Git](http://mongoose.ws/tutorials/tools/#git)
-
-Now, when all required tools are installed, start a terminal/command prompt,
-and download the Mongoose repository, go to the HTTP server example, build it, and run it:
 
 ```sh
 git clone https://github.com/cesanta/mongoose

+The above commands download Mongoose Library source code, then go into the
+HTTP server example directory, and execute `make` command. It uses a

+It builds an example executable and runs it.

-> When done, you can build baremetal embedded examples:

-cd examples/stm32/nucleo-h743zi-baremetal
-make build
