+## FAQ
+
+* Command `cmake ../` stuck at `Cloning into 'eigen'...` or other cloning.
+
+    This may caused by problem of accessing github. Please first try use [SJTU VPN](!https://net.sjtu.edu.cn/wlfw/VPN.htm) and compile. 
+
+    Also, some repos are available on our own server, such as *Eigen*. The download info of libigl dependencies is located at file `libigl/cmake/LibiglDownloadExternal.cmake`. For example, you can change the link at line 70 to `http://dalab.se.sjtu.edu.cn/gitlab/xiaoyuwei/eigen.git` use eigen mirror repo at DALAB server.
+
+    glfw (http://dalab.se.sjtu.edu.cn/gitlab/xiaoyuwei/glfw.git) and imgui (http://dalab.se.sjtu.edu.cn/gitlab/xiaoyuwei/imgui.git) are also available on our server.
