 Automated time lapse photography using gphoto2.
 
 ## Installation
 
-1. Install gphoto2
+1. Install gphoto2 and ffmpeg
 
-  * macOS: `brew install gphoto2`
-  * Debian/Ubuntu: `sudo apt install gphoto2`
+  * macOS: `brew install gphoto2 ffmpeg`
+  * Debian/Ubuntu: `sudo apt install gphoto2 ffmpeg`
 
 2. `gem install tlapse`
 
 ## Example: Integrate with cron
 
-* From 9 AM to sunset, capture one image every 10 minutes
+* From 9 AM to 1 PM, capture one image every 10 minutes
 
 ```
-0 9 * * * cd $HOME && eval "$(tlapse until_sunset --interval 10)" >> capture.log
+0 9 * * * cd $HOME && tlapse alpha capture --until 1pm --interval 10
 ```
 
+* From 3 PM to sunset, capture an image every minute. Compile the result into a video.
+  * You should [configure](#configuration) your coordinates to accurately
+    determine sunset in your location
+
+```
+0 15 * * * cd $HOME && tlapse alpha capture --until sunset --interval 10 --compile
+```
+
 ## CLI
 
 Find better documentation by running `tlapse help` or `tlapse help SUBCOMMAND`
 
 * `tlapse capture_single` - Capture an image using the tethered camera
 * `tlapse until_sunset` - Generate a gphoto2 command which captures images until sunset
+  * You should [configure](#configuration) your coordinates to accurately
+    determine sunset in your location
 
+#### Alpha CLI
+
+These are early-stage features which are likely to change quite a bit before they're ready for prime time.
+
+* `tlapse alpha capture` - Capture a series of timelapse images (see `tlapse alpha capture --help` for options)
+
 ## API
 
 Mostly useful for cronjobs and the like.
 
 * Capture images between given hours

 * Capture images from sunset to sunrise
   ```ruby
   Tlapse::Capture.timelapse_command_while_sun_is_up(interval: 30.minutes)
   # => "gphoto2 --capture-image-and-download -I 1800 -F 11 --filename '%Y-%m-%d_%H-%M-%S.jpg'"
   ```
+
+## Configuration <a name="configuration"/>
+
+So sunrise and sunset calculations are correct for your location, it is
+advisable to configure your (approximate) coordintes using the CLI. Defaults are
+for Raleigh, NC, which is probably not where you live.
+
+You can get rough coordinates from https://www.iplocation.net/
+
+```
+tlapse config set lat YOUR_LATITUDE
+tlapse config set lon YOUR_LONGITUDE
+
+# Optionally also configure your timezone to make date formatting nicer
+tlapze config set tz YOUR_TIMEZONE (e.g. America/New_York)
+```
