 This checker module is used to verify and validate cloud
 after the deployment using number of routines to create reports
 
-# Local run
+# Background.
+Many of our deployments comes with the monitoring solutions, but none of them keeps track of the package versions that is included in release.
+nd it is very important to have proper package versions. That is critical for cloud stability.
+here is more, it is critical to keep track of configuration values for networks (and others too..) in Runtime, in Configuration and at Reclass.
+Also, it is important to keep track of the changes in reclass and be able to have tool that gives clear report on what has been changed.
+
+So, this tool here that can do some checks on the cloud that will be handy for:
+- Engineers that deployed the clouds and need to be sure that proper versions installed on every node
+- Services Team to check cloud at deploy time
+- ProdCare engineers that is supporting client environments
+- Support team
+
+Main use cases for the MCP-checker is:
+- Generate a package versions report that will show which package versions must be payed attention on: Installed vs Candidates vs Release Notes. This will really help on understanding if some node has some strangely versioned package
+- Generate network check against running nodes to collect IPs, mach them into subnets and check MTUs in Runtime (ip a) vs reclass configuration
+- Compare two reclass models recursively (folder1 vs folder2) and generate differences report.
+
+# Installation
 It is pretty simple: 
 - deploy on cfg node, using root creds, on /root/
 ```bash
-git clone https://github.com/savex/salt-cfg-checker
-cd salt-cfg-checker
+git clone http://gerrit.mcp.mirantis.com/mcp/cfg-checker
+cd cfg-checker
 virtualenv .cfgcheck
 source .cfgcheck/bin/activate
 pip install -r requirements.txt
 ```
 - you can check your local.env file for parameters (no need to update for running on cfg node)

-- packages report (CSV): `mcp_check packages report --csv cloud-packages.csv`

+# Running
+- Packages report (HTML): `mcp_check packages report --html __packages_html_filename.html__`
+- Packages report (CSV): `mcp_check packages report --csv __packages_csv_filename.csv__`
+- Network check (CLI output): `mcp-checker network check`
+- [Work in progress] Network check (HTML report): `mcp-checker network report --html __network_html_filename.html__`
+- List folders that can be used for Reclass Compare: `mcp-checker reclass list -p __models_path__`
+- Compare two Reclass models (file and parameter wise): `mcp-checker reclass diff --model1 __model1_path__ --model2 __model2_path__ --html __reclass_html_filename.html__`
 
 # External cloud
 You can also create your env file to connect to env
