+File ACTivity is a file integrity monitoring tool designed to help with PCI DSS
+compliance, which requires a change detection mechanism. It's implemented as a
+BPF agent, which coordinates a set of BPF programs attached to LSM hooks,
+receives events from the kernel, does basic enrichment and pushes them for
+further processing.

 ## Prerequisites
 
 1. stable rust toolchains.

 Cargo build scripts are used to automatically build the eBPF correctly
 and include it in the program.
 
+For more details about available options, check out the

 ## Running eBPF unit tests
 
 There is some specific unit tests that execute just the eBPF code and

+## Configuration options
+
+### Environment variables
+
+* `FACT_PATHS`: List of file paths to monitor.
+
+* `FACT_LOGLEVEL`: At which level produce log messages.
+
+### Commandline options
+
+* `--skip-pre-flight`: Do not perform pre-flight checks. Before starting up
+  Fact tries to verify if needed LSM hooks are available, but in some
+  environments this might not be robust enough. In such cases one can disable
+  those checks.
+
+* `-p, --paths`: List of file paths to monitor. This option could be used
+  multiple times, instructing Fact to monitor multiple files.
