+# i2v (Image to Video)
+
+## Get set up with stability.ai
+
+Set up an account with stability.ai add credits and set up an API key here: https://platform.stability.ai/account/keys
+
+Once you've created an API key you should set it as an environment variable on your system. Specific instructions for each platform can be found below.
+
+## How to install
+
+### Windows
+
+Download the file `i2v-windows-amd64.exe` or `i2v-windows-arm64.exe`. Place the file somewhere on your path. I usually change the name of the file to `i2v.exe`.
+
+I usually have a folder named 'bin' in my user's home folder. I then make sure that folder is on my path by adding it to the path system environment variable. Here is a link with instructions on how to do that: https://learn.microsoft.com/en-us/previous-versions/office/developer/sharepoint-2010/ee537574(v=office.14)
+
+To set the API key in your environment you can follow the above linked instructions for updating your PATH variable but instead of changing your PATH, you can create a new variable.
+
+It should be called `STABILITY_API_KEY` and should have the value of the API key you created when you set up your stability.ai account.
+
+### Mac
+
+Download the file `i2v-darwin-amd64` or `i2v-darwin-arm64`. Place the file somewhere on your path. I usually change the name of the file to `i2v`.
+
+Set an environment variable named `STABILITY_API_KEY` with the value of the API key created when you set up your stability.ai account.
+
+### Linux
+
+Download the file `i2v-linux-amd64` or `i2v-linux-arm64`. Place the file somewhere on your path. I usually change the name of the file to `i2v`.
+
+Set an environment variable named `STABILITY_API_KEY` with the value of the API key created when you set up your stability.ai account.
+
+## Usage
