 A daemon to mirror remote Git repositories and serve them over HTTP, automatically updating the mirror as needed.
 
-It was developed to be used in CI environments to improve the performance of Git clone operations.
+It was developed to be used in CI environments to improve the performance of Git clone and fetch operations.
 
 The project is a C++ clone of jonasmalacofilho's [git-cache-http-server](https://github.com/jonasmalacofilho/git-cache-http-server).
+However, there are these differences and improvements:
+* The repository cache is updated sequentially and for each git fetch or clone operation to avoid race conditions when the remote is updated while some request is updating the cache.
+* The authentication works by fetching or cloning the remote instead of testing if the remote is accessible using the credentials.
+* It can easily be configured to run as a systemd daemon.
 
 ## Build Instructions
 
-* Clone the repository and initialize submodules.
-* Build the project with `cmake`.
-* You can build a `deb` package using the target `package` in CMake.
+It was developed on Debian-based platforms, it can probably also be compiled on other platforms, but don't ask me how.
+
+* Clone the Git repository and initialize submodules.
+* Install zlib1g-dev `sudo apt-get install zlib1g-dev`
+* Build the project with CMake.
+* You can build a *deb* package using the target *package* in CMake.
 
 ## Server Setup
 
-* Install `git`.
-* Install `gchsd` from the `deb` package.
-* Configure a cache directory (default is `/tmp/gchsd`) and listen port (default is `80`) in `/etc/gchsd.conf`.
-* Start the `gchsd` daemon with `sudo systemctl start gchsd`.
+* Install *git*.
+* Install *gchsd* from the *deb* package.
+* Configure a cache directory (default is */tmp/gchsd*) and listen port (default is *80*) in */etc/gchsd.conf*.
+* Start the *gchsd* daemon with `sudo systemctl start gchsd`.
   * You can use `sudo systemctl enable gchsd` to start the daemon automatically after a system restart.
 
 ## Client Setup
 
-* Run `git config --global url."http://<mirror_server_addr>/".insteadOf https://` to use the mirror instead of the original source.
+* Run `git config --global url."http://<mirror_server_addr>/https://".insteadOf https://` to use the mirror instead of the original source.
