-A docker container for [gifify](https://github.com/vvo/gifify)
+A docker container for [gifify](https://github.com/vvo/gifify). Based on the work of [maxogden](https://github.com/maxogden/gifify-docker) and [STRML](https://github.com/STRML/gifify-docker).
 
-![docker-badge](http://dockeri.co/image/maxogden/gifify)
+![docker-badge](http://dockeri.co/image/dersimn/gifify)
 
-## installation
+# Installation
 
 1. install docker
-2. run `docker run -it --rm -v $(pwd):/data maxogden/gifify source.mov -o output.gif`
+2. run `docker run -it --rm -v $(pwd):/data dersimn/gifify source.mov -o output.gif`
 
-When you run `docker run maxogden/gifify` it executes the `gifify` command in `/data` inside the docker ubuntu VM, so in order for this to work you must mount your current working directory as `/data` in the volume. This is what `-v $(pwd):/data` does in the command above.
+When you run `docker run dersimn/gifify` it executes the `gifify` command in `/data` inside the docker ubuntu VM, so in order for this to work you must mount your current working directory as `/data` in the volume. This is what `-v $(pwd):/data` does in the command above.  
+You could also specify this command as an alias in your `.bashrc` file, for e.g.:
+
+    alias gifify='docker run -it --rm -v $(pwd):/data dersimn/gifify'
+
+and use it like
+
+    gifify source.mov -o output.gif
+
+
+## Usage Examples
+
+    docker run -it --rm -v "$(pwd)":/data dersimn/gifify source.mov -o output.gif
+
+Fit video in a 350x350 rectangle and don't scale up if it's smaller:
+
+    docker run -it --rm -v "$(pwd)":/data dersimn/gifify source.mov -o output.gif --resize w=350:h=350:force_original_aspect_ratio=decrease
+
