 [cms-meta-tools](https://github.com/Cray-HPE/cms-meta-tools) repo. See that repo for more details.
 
 ## Local Builds
 If you wish to perform a local build, you will first need to clone or copy the contents of the

+cms-meta-tools repo to `./cms_meta_tools` in the same directory as the `Makefile`. When building
+on github, the cloneCMSMetaTools() function clones the cms-meta-tools repo into that directory.
 
-### Versioning
-Use [SemVer](http://semver.org/). The version is located in the [.version](.version) file.
+For a local build, you will also need to manually write the .version, .docker_version (if this repo
+builds a docker image), and .chart_version (if this repo builds a helm chart) files. When building
+on github, this is done by the setVersionFiles() function.
+
+## Versioning
+The version of this repo is generated dynamically at build time by running the version.py script in 
+cms-meta-tools. The version is included near the very beginning of the github build output. 
+
+In order to make it easier to go from an artifact back to the source code that produced that artifact,
+a text file named gitInfo.txt is added to Docker images built from this repo. For Docker images,
+it can be found in the / folder. This file contains the branch from which it was built and the most
+recent commits to that branch. 
+
+For helm charts, a few annotation metadata fields are appended which contain similar information.
+
+For RPMs, a changelog entry is added with similar information.
