 a large, complex pre-existing codebase.
 To modify such code, GPT needs to understand the dependencies and APIs
 which interconnect all of its subsystems.
-Depending on the coding task, it may be hard
- to determine which parts of the codebase are relevent to solving the task.
-Even assuming we can identify all the needed context, we must
-ensure that it fits within GPT-4's 8k-token
-context window.
+Somehow we need to provide this "code context" to GPT
+when we ask it to accomplish some coding task. Specifically, we need to:
+
+  - Help GPT understand the overall codebase, so that it
+can decifer the meaning of code with complex dependencies and generate
+new code that respects existing abstractions.
+  - Convey all of this "code context" to GPT in an
+efficient manner that fits within the 8k-token context window.
 
 To address these issues, `aider` has
 a new experimental feature that utilizes `ctags` to provide
-GPT with a **concise map of your whole git repository** including
+GPT with a **concise map of your whole git repository** that includes
 all declared variables and functions with call signatures.
 This *repo map* enables GPT to better comprehend, navigate
 and edit the code in larger repos.
