 When you are done building, you need to do a few things in the [Configuration](https://github.com/zcash/zcash/wiki/1.0-User-Guide#configuration) section of the Zcash User Guide differently because we are on the Mac. All instances of `~/.zcash` need to be replaced by `~/Library/Application\ Support/Zcash`

+## VerusCoin version 0.3.10-beta
+VerusCoin is a new, mineable and stakeable cryptocurrency. It is a live fork of Komodo that retains its Zcash lineage and improves it. VerusCoin will leverage the Komodo platform and dPoW notarization for enhanced security and cross-chain interoperability. We have added a variation of a zawy12, lwma difficulty algorithm, a new CPU-optimized hash algorithm and a new algorithm for fair proof of stake. We describe these changes and vision going forward in a [our Phase I white paper](http://185.25.51.16/papers/VerusPhaseI.pdf) and [our Vision](http://185.25.51.16/papers/VerusVision.pdf).

 ## Komodo with Bitcore
 This version of Komodo contains Bitcore support for komodo and all its assetchains.

 ## Komodod
-This software is Komodo client, generally you will use this if you want to mine KMD or setup a full node.
-It downloads and stores the entire history of Komodo transactions; depending on the speed of your computer and network connection, the synchronization process could take a day or more once the blockchain has reached a significant size.
+This software is the VerusCoin enhanced Komodo client. Generally, you will use this if you want to mine VRSC or setup a full node. When you run the wallet it launches komodod automatically. On first launch it downloads Zcash parameters, roughly 1GB, which is mildly slow.
+The wallet downloads and stores the block chain or asset chain of the coin you select.

-We have a release process that goes through several stages before it reaches master. This allows the most conservative users just use the master branch, which is only updated after the other branches have signed off on a release.
+We develop on dev and some other branches and produce releases of of the master branch, using pull requests to manage what goes into master.

-99% of the activity is in the dev branch, this is where I am testing each change one by one and there are literally thousands of updates. Only use this branch if you really want to be on the bleeding edge. I try to keep things stable, but there are times where necessarily there are bugs in the dev branch, since I am actively developing and debugging here. A good rule is to wait for at least 4 hours from the last update before using the dev branch (unless you know what you are doing)
-
-After things look good in the dev branch, it is propagated to the beta branch, this is the version the notary nodes use. They are knowledegable command line server guys and so they have a keen eye for anything that wasnt caught during the dev cycle.
-
-After the notary nodes verify things are working and the latest release is deemed stable, it is propagated to the dPoW branch. From here an automated Jenkins process builds it for all OS, and since the notary nodes are all unix, it is possible for some issues to be caught at this stage. The dPoW branch is what goes into the GUI installers.
-
-After the GUI are updated and released and it is verified that no significant support issues were created, the master branch is finally updated.
-
-Master branch: exchanges and users that build from the repo without changing branches
-dPoW branch: autobuild into GUI installers, unix, osx, windows
-beta branch: notary nodes, command line unix
-dev branch: bleeding edge, possibly wont even compile, multiple updates per hour

 And make sure to delete all traces of this when the JUMBLR is finished. You will end up with 100 addresses that have an average of 1000 KMD each. So as long as you are careful and dont do a 10,000 KMD transaction (that will link 10 of your secret addresses together), you can appear as 100 different people each with 1000 KMD.

+VerusCoin Command Line Tools v0.3.9-beta
+Contents:
+komodod - VerusCoin's enhanced Komodo daemon.
+komodo-cli - VerusCoin's enhanced Komodo command line utility.
+verus - wrapper for komodo-cli that applies the command to the VRSC coin
+verusd - wrapper for komodod that sets the VerusCoin parameters to defaults properly
+fetch_params.sh - utility to download the zcash parameters needed to start the VerusCoin command line tools and scripts
+lib*.dylib - assorted dynamic libraries, dependencies needed by fetch-params.sh, komodod and/or komodo-cli
+
+Command line tools are run from the terminal. You can launch the terminal on a Mac by using the Finder, selecting Applications and from that select Utilities, finally selecting Terminal from the Utilities folder.
+You will need to switch to the directory you extracted the verus-cl into. If you extracted it in the Download folder then the change directory command is
+cd ~/Downloads/verus-cli
+The first time on a new system you will need to run ./fetch-params before using komodod or verusd.
+
+Run ./verusd to launch komodod, and use verus to run commands such as:
+./verus stop
+Which signals komodod (if it is running) to stop running.

+VerusCoin Command Line Tools v0.3.10-beta
+Contents:
+komodod.exe - VerusCoin's enhanced Komodo daemon
+komodo-cli.exe - VerusCoin's Komodo command line utility
+verus.bat - wrapper for komodo-cli that applies the command to the VRSC coin
+verusd.bat - wrapper for komodod that sets the VerusCoin parameters to defaults properly
+
+You need to run a command prompt, for example hit <Ctrl><Esc> and type cmd<Enter>
+From the command prompt change to the directory where you installed verus-cli. If you downloaded the file to your Downloads directory and extracted it there then the change directory command is
+cd \Users\MyName\Downloads\verus-cli
+From this directory you can run the Verus command line utilities.
+The first time on a new system you will need to run fetch-params before using komodod.exe or verusd.
+Many anti-virus products interfere with the VerusCoin tool's ability to open ports and will need to be configured to allow what the scanner says is unsafe behavior.
+Extreme cases can result in the virus scanner deleting Agama.exe or moving it to "protect" the system. You will to add the executables to a whitelist and re-extract the verus-cli-windows.zip file if that happens.
+Run verusd.bat to launch komodod, and use verus.bat to run commands such as:
+verus.bat stop
+Which signals komodod.exe (if it is running) to stop running.
+
+Note that if you pass in command line options to verus.bat or verusd.bat that include an = like -ac_veruspos=50 you must surround it with double quotes like this:
+verusd.bat "-ac_veruspos=50"
+Otherwise Windows will drop the = and pass the two values in as separate command line options.
