# TO CIRCUMVENT YOUR GOVERNMENT'S FIREWALL RESTRICTION

Because SoftEther VPN is overly strong tool to build a VPN tunnel,
some censorship governments want to block your access to the source code
of SoftEther VPN, by abusing their censorship firewalls.

To circumvent your censor's unjust restriction,
SoftEther VPN Project distributes the up-to-date source-code
on all the following open-source repositories:

  - GitHub
    https://github.com/SoftEtherVPN/SoftEtherVPN/

```
$ git clone https://github.com/SoftEtherVPN/SoftEtherVPN.git
```

  - GitLab (mirrored from GitHub)
    https://gitlab.com/SoftEther/SoftEtherVPN/

```
$ git clone https://gitlab.com/SoftEther/SoftEtherVPN.git
```

We hope that you can reach one of the above URLs at least!
