+Log2Array processes all logs through a list of regex patterns. If a log matches a pattern successfully, it's grouped and variables are inserted into DuckDB. If a log doesn't match any patterns, it's buffered. These buffered logs are used to detect log communities via a text embedding model. Samples from each community are then sent to GPT-4 to extract their regex patterns.
+
+The pattern flow isn't part of the main processing, which means that after an initial bootstrap, the processing speed increases significantly. Thus, the longer Log2Array runs, the higher the logs/sec rate it has.
+
 ## How to install it?
-`pip install git@https://github.com/ethe/log2array.git`
+```
+  ↳pip install git@https://github.com/ethe/log2array.git
+
+  ↳ python3 -m log2array
+Usage: python -m log2array [OPTIONS] COMMAND [ARGS]...
+
+Options:
+  --help  Show this message and exit.
+
+Commands:
+  clean
+  run
+```
+
+*Logs2Array requires Python3.9+*
+
+## How much I pay?
+Log2Array uses GPT-4 to extract the regex of log community, each extraction would cost hundreds to thousands tokens of GPT-4. This means each log community detection would costs 0.01$ to 0.1$.
+
+## What is the next?
