 ## Bot trigger and entry-point
 
-TODO: doc
+This bot is generally triggered by a GitHub workflow listening for new issues
+on the dart-lang/sdk repo.
+
+See https://github.com/dart-lang/sdk/blob/main/.github/workflows/issue-triage.yml.
 
 ## Overview
 
-TODO: doc
+The general workflow of the tool is:
+
+- download the issue information (existing labels, title, first comment)
+- ask Gemini to summarize the issue (see [prompts](lib/src/prompts.dart))
+- ask Gemini to classify the issue (see [prompts](lib/src/prompts.dart))
+- create a comment on the issue ( `@dart-github-bot`) with the summary;
+  apply any labels produced as part of the classification
 
 ## Tuning
 
-TODO: doc
+We create a tuned Gemini model in order to improve the performance of
+classification. This involves:
+
+- downloading recent, already triaged issues (~800 issues)
+- writing them in a format suitable for tuning (either .csv or .jsonl)
+- tuning via the Gemini APIs; this gives us a new model name to use when
+  calling Gemini (e.g., `model: 'tunedModels/sdk-triage-tuned-prompt-1l96e2n'`)
+
+See [tool/create_tuning_data.dart](tool/create_tuning_data.dart).
