 ## HW1 for gensec
+This is a RAG LLM application for asking questions about Kerbal Space Program (KSP). KSP and KSP 2 are very technical games relying on orbital physics and players often want to quickly learn more about celestial body characteristics, common orbital manuevers, delta-v requirnments, and so-on. The player maintined [wiki](https://wiki.kerbalspaceprogram.com/) contains almost all of this information, so my application uses this as a primary source 
 
 ### Enviornment
-pip install -r requirements.txt
\ No newline at end of file
+Install python3, then run the following:
+```
+pip install -r requirements.txt
+touch .env
+```
+After, populate .env with your OPENAI_API_KEY and FIREWALL_API_KEY
+
+### Loading
+This will take some time (2 minutes for ~75), so be patient. Firewall does have support to query for the status of a long running API call, so I will add status feedback later
+```
+python3 loader.py
+```
+
+### Testing
+The loaded documents can be tested at this point with the search script
+```
+python3 search.py
+```
+
+### Running
+```
+python3 app.py
+```
+
+### Example Questions
+```
+llm>> How much delta-V is required to exit Kerbin?
+llm>> How many moons does Jool have?
+llm>> How large is Gilly's sphere of influence?
+llm>> Describe Eve's physical characteristics
+llm>> Does the game support multiplayer?
+llm>> Which engines are good for deep space travel?
+
+```
+
+Enjoy!
