+#+title: FreshRSS2Pocket
+
+One-Way-Synchronization of your starred FreshRSS items to Pocket.
+
+* Requirements
+
+- Pocket application.
+- [[https://www.freshrss.org/][FreshRSS]] instance
+- Python 3
+
+* Features
+
+- Adds starred FreshRSS items to your Pocket account (including title and categories)
+- Removes starred items from FreshRSS
+
+* Shortcomings
+
+- None that I'm currently aware of.
+
+* Setup
+
+- Create a new Pocket application in the [[https://getpocket.com/developer/apps/][Pocket developer portal]] of type "Desktop (other)" (not sure if the type really matters)
+- Copy =config.example.json= to =config.json= and fill it out
+- (optional) Create a Python virtual environment with =python3 -m venv venv= and activate it
+- Install Python requirements with =pip install -r requirements.txt=
+- Execute the program with =python youtube2freshrss.py=
+- (optional) Set up a Cron job for running the =run.sh= (requires virtual environment) once a day with the working directory as first argument
