 getting started: https://github.com/ipfs/community/issues/177 <br> 
 libp2p: https://github.com/libp2p/specs <br>
+<br>
+Prerequisites: To compile the C version you will need:<br>
+lmdb https://github.com/jmjatlanta/lmdb<br>
+c-protobuf https://github.com/kenCode/c-protobuf<br>
+c-multihash https://github.com/kenCode/c-multihash<br>
+c-multiaddr https://github.com/kenCode/c-multiaddr<br>
+c-libp2p https://github.com/kenCode/c-libp2p<br>
+<br>
+And of course this project at https://github.com/kenCode/c-ipfs<br>
+<br>
+The compilation at this point is simple, but not very flexible. Place all of these projects in a directory. Compile all (the order above is recommended) by going into each one and running "make all".
