 To run fine tuning for any user specific dataset, prepare the dataset using the following steps:
 
-    1) Create a  directory named 'dataset' inside efficient-transformers. 
+    1) Create a directory named 'dataset' inside efficient-transformers. 
     2) Inside this directory, create a file named 'custom_dataset.py'. This is different than the custom_dataset.py present at efficient-transformers/QEfficient/finetune/dataset.
     3) Inside the newly created efficient-transformers/dataset/custom_dataset.py, define a function named 'get_custom_dataset'. 
     4) get_custom_dataset() should have following 4 parameters:  dataset_config, tokenizer, split, context_length. This function gets called twice through Qefficient/cloud/finetune.py with the name get_preprocessed_dataset.
