I highly recommend this magazine when you are ready to start reading. It is aimed at learners and has articles at three different levels of difficult. Definitions for many words are provided right with each article to help with understanding. It is pricey if you are outside Europe, but there is now an app for iOS and Android, and the issues are very inexpensive that way ($1.99 each for me in the US). You can search the forum for “Lingo Newydd”, to learn more, and here are a couple of links if you are interested:
