+# SONiC - SAI Redis - sairedis
+
+## Description
+The SAI Redis provides a SAI redis service that built on top of redis database. It contains two major components, 1) a SAI library
+that puts SAI objects into the redis database, 2) a syncd that takes the SAI objects and puts them into the ASIC.
+
+## Getting Started
+
+### Install
+
+Before installing, add key and package sources:
+
+    sudo apt-key adv --keyserver apt-mo.trafficmanager.net --recv-keys 417A0893
+    echo 'deb http://apt-mo.trafficmanager.net/repos/sonic/ trusty main' | sudo tee -a /etc/apt/sources.list.d/sonic.list
+    sudo apt-get update
+
+Install dependencies:
+
+    sudo apt-get install redis-server -t trusty
+    sudo apt-get install libhiredis0.13 -t trusty
+
+There are a few different ways you can install sairedis.
+
+#### Install from Debian Repo
+
+For your convenience, you can install prepared packages on Debian Jessie:
+
+    sudo apt-get install libsairedis syncd
+
+#### Install from Source
+
+Checkout the source: `git clone https://github.com/Azure/sonic-sairedis.git` and install it yourself.
+
+Get SAI header files into /usr/include/sai. Put the SAI header files that you use to compile
+libsairedis into /usr/include/sai
+
+Get ASIC SDK and SAI packages from your ASIC vendor and install them.
+
+Install prerequisite packages:
+
+    sudo apt-get install libswsscommon libswsscommon-dev
+
+You can compile and install from source using:
+
+    ./autogen.sh
+    make && sudo make install
+
+You can also build a debian package using:
+
+    ./autogen.sh
+    fakeroot debian/rules binary

+
+### GitHub Workflow
+
+We're following basic GitHub Flow. If you have no idea what we're talking about, check out [GitHub's official guide](https://guides.github.com/introduction/flow/). Note that merge is only performed by the repository maintainer.
+
+Guide for performing commits:
+
+* Isolate each commit to one component/bugfix/issue/feature
+* Use a standard commit message format:
+
+>     [component/folder touched]: Description intent of your changes
+>
+>     [List of changes]
+>
+> 	  Signed-off-by: Your Name your@email.com
+
+For example:
+
+>     swss-common: Stabilize the ConsumerTable
+>
+>     * Fixing autoreconf
+>     * Fixing unit-tests by adding checkers and initialize the DB before start
+>     * Adding the ability to select from multiple channels
+>     * Health-Monitor - The idea of the patch is that if something went wrong with the notification channel,
+>       we will have the option to know about it (Query the LLEN table length).

+>       Signed-off-by: user@dev.null
