-# codimd_note_overview
+# CodiMD note overview
+
+a searchable list of existing markdown files from CodiMD, i.e., [https://hackmd.wiai.de/](https://hackmd.wiai.de/), featuring sortable columns and fancy emojis where applicable.
+
+![demo.jpg](demo.jpg)
+
+## Testing locally
+
+
+Execute `docker build . --tag codimd; docker run -p 5000:5000 --env TESTING=True codimd` to run the app in testing mode locally. No database credentials are required for test
+
+### Open issues
+
+* make the layout responsive
+* either read the DB credentials and URL from the environment or the config file
+* load test data from a local file when run in testing mode 
+* add more/real testing data
+* the up and down arrows in the table head fields are not invisible
+* add more emojis ヘ( ^o^)ノ＼(^_^ )
