@@ -10,17 +10,33 @@ Examples of common used functions are:
  - `sormq(int conn, char *sql, ...)` execute query. Variadic arguments. Works like `printf`. Returns result in CSV format in case of `SELECT`.
  - `sorm_csvd(char *csv_data)` dumps your CSV result data to a nice fixed content width table in the terminal.
 
-## CAUTION
-This project won't compile on your local PC because `rlib.h` is missing. This is my bundle of libraries that I regularely use. I will add this later as 3rd party lib. Maybe I will cherry pick only the functions that SORM uses out of it to keep the source clean, else I will have thousands of lines nothing to do with this project in the source.

-## Thread safety
-I wonder if I have configured sqlite3 the right way for thread safety. It maybe requires a manual compilation of the shared object file. Will look into that. SORM is written with thread safety in mind.

 ## Design choices
 I use mainly native types and not custom structs. For example, the db parameter is an int. This is so it can easily communicate with other languages using a shared object file.
 Same argument is for the result set of `sormq` (the query function) resulting in a `char *` containing CSV data. 
 While the performance is nice, it's not written with performance in mind at all.

+## Building
+
+It has only one build command for the shared object file and the REPL/CLI.
+It has not been compiled with optimizations / warnings enabled. Don't recommend for now.
+```bash
+make build
+```
+### Requirements
+This project has the following dependencies:
+ - sqlite3-dev (`apt install sqlite3-dev`)
+ - readline(-dev?) (no idea how to install)
+ - gcc 
+ - make
+It probably works from C99 to C2X.

 ## Python support
 The Python library is low quality. I made it just for fun and test. This is not a defitive version. But it show very well how to communicate with a shared object file. I'm sure someone will be happy with examples how to use variadic functions trough Python to C. See `sorm.py`
