 This project was initiated to create a compiled client from PHP sources that can be configured with an ini file to perform needed checks. Such a binary is independent from any programming language.
 
-### Requirements
+### The result
 
-#### For usage of the client
+A single binary without dependencies can be put on a Linux target host.
+It can perform all checks that the current Appmonitor client as Php client can execute.
+
+With command line parameter `--ini=<INIFILE>` it processes the checks that are defined there.

 💡 **Idea**: For non PHP systems we prepare a compiled binary containing all written PHP checks. Then those non PHP systems do not need to implement the checks again.

-## Installation
-
-How to bring up this project to live:
-
-Clone this repository.
-
-You get this initial structure:
-
-```txt
-.
-├── build.php
-├── inc_functions.php
-├── inc_vars.php
-├── installer.php
-├── readme.md
-└── src
-    └── amcli.php
-```
-
-Run the `./installer.php` to download spc and prepare the micro build.
-
-The newly created dirs:
-
-```txt
-.
-├── build            << working directory for builds
-│   
-├── external
-│   ├── appmonitor   << cloned IML appmonitor project
-│   └── bin
-│       └── spc      << downloaded spc binary
-:
-```
-
-## Update
-
-Run the installer again.
-
-if you want to install a newer version of spc: remove the external/bin/ directory and run the installer again.
-
-## Start over
-
-Remove the dirs
-
-- built_packages
-- build
-- external
-
-And this file
-
-- src/include_checks.php
-
-Then start `./installer.php` and `./build.php`
-
-## Compile
-
-To compile `src/amcli.php`to `built_packages/amcli` start the `./build.php`
+The binary has parameter support. It parses an ini file that containes metadata and all checks.
