Introducing HackMD Enterprise Edition
Dear Markdown hackers,
We are introducing **HackMD Enterprise Edition (EE)**, a new HackMD service with features specifically designed for knowledge sharing and collaboration. We are releasing these features to a new service for try out: Demo.hackmd.io. More importantly, we want to take this chance to thank you.
### Thank You
We've seen significant growth in HackMD.io in the past six months. Our hosted notes increased from 100,000 in March to more than 220,000 today. Our registered users had doubled from 16,000 to more than 33,000. We've been blown away by how quickly our project went viral and humbled by all the support HackMD had received. We want to say thank you and assure you that we are committed to keep making HackMD the best tool for knowledge management and collaboration with Markdown syntax. We've heard all your questions, comments, suggestions, and complaints. We deeply appreciate all of them.
### HackMD Enterprise Edition (EE)
HackMD(EE) is our response to your requests. We added two long-awaited features so you could have better control over your private information:
* HackMD(EE) comes with **Advanced Permission Controls** for each note. You can now invite registered users to your note and set individually read, write, or admin priviledge for each invitee.
* With HackMD(EE), you can now keep all your images private with our **Private Images Hosting** service.
To improve your experience organizaing knowledge, HackMD(EE) now comes with a new **Overview Page** to aid notes organization and knowledge discovery. With the **Book Mode** released earlier, your notes could now be viewed and found the way your think of them in your mind.
To free our users from the overhead of managing their own instances, HackMD(EE) would be a hosted **Software-as-a-Service (SaaS)** offering. We now provide service manager a **Dashboard** for notes management and users access monitoring. Customer supports and other customizable options are also available. Leave the maintenance and other hassles to us, so you can focus on making great things and sharing valuable insights.
### New Playground: Demo.HackMD.io
Features available in HackMD(EE) would be available in demo.hackmd.io, an instance with ephemeral storage. User of this instance would have access to dashboard and advanced permission controls, among other new enterprise features of HackMD(EE). However, notes created on demo.hackmd.io would be deleted weekly. These make demo.hackmd.io a playground great for feature try-outs, disposable notes, or other creative usages.
### HackMD.io Remains Free
For the past two years, we've run HackMD.io as a free service providing real-time collaboration and knowledge management across the globe. HackMD.io hosted shared notes for countless tech conferences, meetups, seminars, and hackathons. We are so grateful to be part of the exchange of so many great ideas. We are therefore committed to **keep HackMD.io free and open to everyone**, as it always was. It is our privilege to have the opportunity to contribute to the greater community. We will keep it that way.
The past two years were quite an adventure. We would like to thank you for all your supports. As always, please don't hesitate to [like us on Facebook](https://www.facebook.com/hackmdio/), join the [chat on twitter](https://twitter.com/hackmdio) or [drop us a mail](mailto:email@example.com) if you have any questions or comments.
