+
+ pfaltgall [options] <configuration file path>
+
+[[[ DESCRIPTION ]]]
+
+ This is pfaltgall v0.1, a CLI PHP script that can generate an html file with
+a gallery from your Pixelfed profile.
+ In order to create it, you just need to login to your Pixelfed account and
+get an app token (Settings -> Applications -> Create new token), then create
+a configuration file for pfaltgall like this (don’t write the «---» lines):
+
+---
+host=your_instance_host
+token=your_token
+---
+
+ For example:
+
+---
+host=pixelfed.social
+token=as7f8a7s0d89f7as97df09a8s7d90f81jkl2h34lkj12h3jkl4
+---
+
+ Then run pfaltgall with the path of the configuration file you have
+created. This will create an «index.html» file that will be ready to be put
+where you want (you can also see it locally, obviously).
