Markdown - Anki viewer for Pythonista. Obtains a Markdown file from Dropbox, hides *em* and **strong** characters, and reveals when they are pressed. Great for remembering something.

# DROPBOX IMPORT FOR PYTHONISTA 3
#
# SETUP INSTRUCTIONS:
#
# 1. Go to https://www.dropbox.com/developers/apps (log in if necessary)
# 2. Select "Create App"
# 3. Configure your app:
# * Select "Dropbox API"
# * Choose whichever access level you prefer ("Full Dropbox" or "App Folder")
# * Enter the app name you wish to use for this script. It must be unique across all Dropbox apps.
# * Select the account to associate with this app.
# * Agree to the terms and conditions and click "Create app"
# 4. On the newly-created app's summary page, click the "Generate"
# button under "Generated access token"
# 5. Copy the generated token and paste it below (replace "YOUR_TOKEN_HERE").
# 6. (optional) Open the "wrench" (actions) menu in Pythonista and add
# this script, so you can run it from everywhere in Pythonista.
# Notes:
# All selected files are downloaded into the root folder of the Pythonista
# script library. If a file with the same name already exists, a numeric
# suffix is appended automatically.
