 The centillion keeps it simple.
 
 
-## quickstart
+## quickstart (with Github auth)
 
-Run the centillion app with a github access token API key set via
-environment variable:
+Start by creating a Github OAuth application.
+Get the public and private application key 
+(client token and client secret token)
+from the Github application's page.
+
+When you create the application, set the callback
+URL to `/login/github/authorized`, as in:
 
 ```
-GITHUB_TOKEN="XXXXXXXX" python centillion.py
+https://<url>/login/github/authorized
+```
+
+Edit the Flask configuration `config_flask.py`
+and set the public and private application keys.
+
+Now run centillion:
+
+```
+python centillion.py
+```
+
+or if you used http instead of https:
+
+```
+OAUTHLIB_INSECURE_TRANSPORT="true" python centillion.py
 ```
 
 This will start a Flask server, and you can view the minimal search engine
-interface in your browser at <http://localhost:5000>.
+interface in your browser at `http://<ip>:5000`.
+
+
+## troubleshooting
+
+If you are having problems with your callback URL being treated
+as HTTP by Github, even though there is an HTTPS address, and
+everything else seems fine, try deleting the Github OAuth app
+and creating a new one.

-current problems:
-- some github issues have no title
-- github issues are just being re-indexed over and over
-- documents not showing up in results
+Main task:
+- hashing and caching
+    - <s>first, working out the logic of how we group items into sets
+        - needs to be deleted
+        - needs to be updated
+        - needs to be added
+        - for docs, issues, and comments</s>
+    - second, when we add or update an item, need to:
+        - go through the motions, download file, extract text
+        - check for existing indexed doc with that id
+        - check if existing indexed doc has same hash
+            - if so, skip
+            - otherwise, delete and re-index
+
+Other bugs:
+- Some github issues have no title (?)
+- <s>Need to combine issues with comments</s>
+- Not able to index markdown files _in a repo_
+- (Longer term) update main index vs update diff index
+
+Needs:
+- <s>control panel</s>
+
+Thursday product:
+- Everything re-indexed nightly
+- Search engine built on all documents in Google Drive, all issues, markdown files
+- Using pandoc to extract Google Drive document contents
+- BRIEF quickstart documentation
+
+Future:
+- Future plans to improve - plugins, improving matching
+- Subdomain plans
+- Folksonomy tagging and integration plans
+
+
+
+
+config options for plugins
+conditional blocks with import github inside
+complicated tho - better to have components split off

+# Centillion Components
+
+Centillion keeps it simple.
+
+There are two components:
+
+* The `Search` object, which uses whoosh and various
+  APIs (Github, Google Drive) to build and manage
+  the search index. The `Search` object also runs all
+  queries against the search index. (See the
+  [Centillion Whoosh](centillion_whoosh.md) page
+  or the `centillion_search`.py` file
+  for details.)
+
+* Flask app, which uses Jinja templates to present the
+  user with a minimal web frontend that allows them
+  to interact with the search engine. (See the
+  [Centillion Flask](centillion_flask.md) page
+  or the `centillion`.py` file
+  for details.)

+
+## What the flask server does
+
+Flask is a web server framework
+that allows developers to define
+behavior for specific endpoints,
+such as `/hello_world`, or
+<http://localhost:5000/hello_world>
+on a web server running locally.
+
+## Flask server routes
+
+- `/home`
+    - if not logged in, this redirects to a "log into github" landing page (not implemented yet)
+    - if logged in, this redirects to the search route
+
+- `/search`
+    - search template
+
+- `/main_index_update`
+    - update main index, all docs period
+
+- `/control_panel`
+    - this is the control panel, where you can trigger
+      the search index to be re-made

+# Centillion Whoosh
+
+The `centillion_search.py` file defines a
+`Search` class that serves as the backend
+for centillion.
+
+## What the Search class does
+
+The `Search` class has two roles:
+- create (and update) the search index
+    - this also requires the `Search` class
+      to define the schema for storing documents
+- run queries against the search index,
+  and package results up for Flask and Jinja
+
+## Search class functions
+
+The `Search` class defines several functions:
+
+- `open_index()` creates the schema
+
+- `add_issue()`, `add_md()`, `add_document()` have three diff method sigs and add diff types
+  of documents to the search index
+
+- `update_all_issues()` or `update_all_md()` or `update_all_documents()` iterates over items
+  and determines whether each item needs to be updated in the search index
+
+- `update_main_index()` - update the entire search index
+    - calls all three update_all methods
+
+- `create_search_results()` - package things up for jinja
+
+- `search()` - run the query, pass results to the jinja-packager

+`config_centillion.json` defines configuration variables

-## work that is planned
+## Control Panel/Rebuilding Search Index
 
-See [plans.md](plans.md)
+To rebuild the search engine, visit the control panel route (`/control_panel`),
+for example at <http://localhost:5000/control_panel>.
+
+This allows you to rebuild the search engine index. The search index
+is stored in the `search_index/` directory, and that directory
+can be configured with centillion's configuration file.
+
+The diff search index is faster to build, as it only
+indexes documents that have been added since the last
+new document was added to the search index.
+
+The main search index is slower to build, as it will
+re-index everything.
+
+(Cron scripts? Threaded task that runs hourly?)

+## Details
+
+More on the details of how centillion works.
+
+Under the hood, centillion uses flask and whoosh.
+Flask builds and runs the web server.
+Whoosh handles search requests and management
+of the search index.
