ShowDoc is an IT tool for sharing documents online. ShowDoc makes it easy to share documents between the members of a team for a more effective communication during group projects. In this step by step guide I will show you how to install ShowDoc on your Synology NAS with Docker.

💡Note: This guide works perfectly with the latest version of ShowDoc v3.3.1

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.
