If you want to get started with Tech correctly, then you should join a Tech community. Advancing in Tech is not a one man thing. You need people.

Where do you find people that can help you become who you want to be in Tech?
In a community 

Here are three reasons you should join a tech community

1. To meet like-minded peers, and make friends in the space.
Association is iimportant if you want to accelerate in any industry. A community makes it easy to meet people who you can build quality friendships with.
2. To access opportunities easily
Details and information about Hackathons, job openings, and free training sessions are shared in Tech communities. You will be doing yourself a lot of disservices if you are not part of one.

3. To access quality mentorship
You will find a lot of experienced mentors in communities. Mentors who know the way, have gone the way and can show you the way are found in communities, There, they offer expert counsel, and help. It's possible that you may not be able to reach them ordinarily, but because of the community, you can reach them.

Community is a cheat sheet. You don't need to make one million mistakes as a beginner in Tech.

Important Information
You get out of a community what you put into it. To leverage community for career growth, you have to be active.

Being active means commenting when need be, engaging with the community's social media content, participating in community activities and attending community events. This is necessary because that's how you get noticed and you differentiate yourself from the crowd.

Some Tech communities have about 30,000 members but majority are not active. Don't join the inactive crew.
