  The main idea behind uashield on Azure is the following: uashield is able to dynamically update proxies and target IPs. So you, as a user, only have to follow the instructions below and as a result you will add a few servers to something like a botnet. Everything else will be done by guys from the uashield community.
  Link to the project: [https://github.com/opengs/uashield](https://github.com/opengs/uashield).

-* Size – Standart\_D2s\_v3 – 2 vcpus, 8 GiB memory. (As you can see, the price for the server is something like 0.129$/hr. With a free 200$ for "Free account" we're able to use 200/0.129 = 1550 hrs of server time for free. For example, 5 servers will work for free for 1550/5 = 310 hrs. If you are not allowed to choose this one, try to find one available with 2 vCPUs and choose it.
+* Size – Standart\_D4s\_v4 – 4 vcpus, 16 GiB memory. (As you can see, the price for the server is something like 0.026$/hr. With a free 200$ for "Free account" we're able to use 200/0.026 = 7692 hrs of server time for free. For example, 10 servers will work for free for 7692/10 = 769 hrs, its about 32 days! If Standart\_D4s\_v4 is not available, try to select other 4 vcpus and 16 GiB memory, but if it is much more expencive, then try other region.

 You have successfully created one server. You can repeat steps 5-11 until you exceed the limit of vCPUs available for your free account (Azure won't let you create one more server).
 
-**Also mention that If you exceed the limit in one region, you can choose another one and you will be able to launch servers there.**
+### IMPORTANT If you exceed the limit in one region, you can try another one and you will be able to launch servers there
+### WARNING Don`t use Australia region. Network traffic is every expensive from there.
