-`pixi add mojo_csv`
 
-##### Basic Usage
+```sh
+pixi add mojo_csv
+```
 
-```mojo
-from mojo_csv import CsvReader
-from pathlib import Path
+## Usage
 
-fn main():
-    var csv_path = Path("path/to/csv/file.csv")
-    var reader = CsvReader(csv_path)
-    for i in range(len(reader)):
-        print(reader[i])
-```
 
-##### Optional Usage
+By default uses all logical cores - 2
+```mojo
+ CsvReader(       
+    in_csv: Path,
+    delimiter: String = ",",
+    quotation_mark: String = '"',
+    num_threads: Int = 0, # default = 0 = use all available cores - 2
+ )
+```
 
 ```mojo
 from mojo_csv import CsvReader
 from pathlib import Path
+from sys import exit
 
-fn main():
+fn main() raises:
     var csv_path = Path("path/to/csv/file.csv")
-    var reader = CsvReader(csv_path, delimiter="|", quotation_mark='*')
+    try:
+        var reader = CsvReader(csv_path)
+    except:
+        exit()
     for i in range(len(reader)):
         print(reader[i])
 ```
 
-#### BETA
-1.4.0 will be the last version where this isn't the default

-ThreadedCsvReader(
-    file_path: Path,
-    delimiter: String = ",",
-    quotation_mark: String = '"',
-    num_threads: Int = 0 # 0 = use all available cores
-)

-### Example 1: Default (All Cores)
+### Delimiters
 
 ```mojo
-var reader = ThreadedCsvReader(Path("large_file.csv"))
-// Uses all 16 cores on a 16-core system
+    CsvReader(csv_path, delimiter=";", quotation_mark='|')
 ```
 
-### Example 2: Custom Thread Count
-
+### Threads
+__force single threaded__
 ```mojo
-var reader = ThreadedCsvReader(Path("data.csv"), num_threads=4)
-// Uses exactly 4 threads
+CsvReader(csv_pash, num_threads = 1)
 ```
-
-### Example 3: Single-threaded
-
+__use all the threads__
 ```mojo
-var reader = ThreadedCsvReader(Path("data.csv"), num_threads=1)
-// Forces single-threaded execution (same as CsvReader)
-```
