+    This app, powered by the IEQ-BERT model (sadickam/sdg-classification-bert), is for automating the classification of text concerning 
+    with respect to indoor environmetal quality (IEQ). IEQ refers to the quality of the indoor air, lighting, 
+    temperature, and acoustics within a building, as well as the overall comfort and well-being of its occupants. It encompasses various 
+    factors that can impact the health, productivity, and satisfaction of people who spend time indoors, such as office workers, students, 
+    patients, and residents. This app assigns five labels to any given text and a text may be assigned one or more labels. The five labels include
+    the following:
+    - Acoustic
+    - Indoor air quality (IAQ)
+    - No IEQ (label assigned when no IEQ is defected)
+    - Thermal
+    - Visual
+
+    Because IEQ-BERT is capable of assigning one or more labels to a text, it is possible that the returned prediction like 
+    (Acoustic_No IEQ) or (NO IEQ_Thermal). These multiple predictions that include "No IEQ" may suggest lack of contextual 
+    clarity in the text and need manual review to affirm label. 
+
+    This app has two analysis modules summarised below:
+    - Single-Text-Prediction - Analyses text pasted in a text box and return IEQ prediction.
+    - Multi-Text-Prediction - Analyses multiple rows of texts in an uploaded CSV file and returns a downloadable CSV file with IEQ prediction for each row of text.
+
+    This app runs on a free server and may therefore not be suitable for analysing large CSV files. 
+    If you need assistance with analysing large CSV, do get in touch using the contact information in the Contact section.
