 Look for meetups and conferences that are relevant to your work.

 If you're [new to public speaking](http://speaking.io/), start by finding a local meetup that's related to the language or ecosystem of your project. If you've never spoken at an event before, it's perfectly normal to feel nervous! Remember that your audience is there because they genuinely want to hear about your work. As you design your talk, remember to focus on what your audience will find interesting and get value out of. Keep your language friendly and approachable. Smile, breathe, and have fun.

 A casual contributor may not have time to get fully up to speed with your project. Nearly half of contributors on popular GitHub projects, for example, [only made one contribution](http://gustavopinto.org/lost+found/saner2016.pdf). This level of noise can be overwhelming at first. But [the more people feel ownership](https://medium.com/node-js-javascript/building-a-better-node-community-3f8f45b45cb5) of your project, the more work can be distributed. It will be less stressful than trying to do everything yourself.
