 We use v0.23.4 because v0.24 sucks
 
 ```shell
-$ wget https://github.com/libgit2/libgit2/archive/v0.23.4.zip
-$ unzip v0.23.4.zip
-```
-Install dependencies: `libssh2`, `http-parser`, `cmake`, `libcurl`.
-
-```shell
-On Mac OSX:
-$ brew install libssh2 http-parser cmake libcurl
-
-On CentOS:
-$ yum install libssh2-devel http-parser cmake libcurl-devel
-```
-Then install libgit2.
-
-```shell
-$ cmake .  -DCMAKE_VERBOSE_MAKEFILE=ON -Wno-dev -DUSE_SSH=YES
-$ make && make install
-```
-Note on Mac OSX may need to set CFLAGS="-std=c99".
-Now libgit2 is installed under `/usr/local/lib` as default. We still need to set pkg-config and link dynamic libraries.

-```shell
-On Mac OSX:
-$ cd /usr/local/lib/pkgconfig
-$ ln -s /path/to/libgit2/pkgconfig/libgit2.pc  libgit2.pc
-$ cd /usr/local/lib
