# Be a part of Wikipedia (Mathematics, Research & Writing)

**Here is how you can help:**

**Click on one of the links** in the list on the left hand side ("List of short mathematics articles that need to be expanded"). This will bring you directly to the article that needs attention.

Read the article and start **researching** the topic. Consider visiting a university or public library to identify and study the best sources.

Once you've completed your research, get back to the article and **click on "Edit"** at the top of the screen (next to the search field):

**Expand** the article. Please keep in mind that all information you had has to be based on verifiable sources. Add the works that you have used to the *References* section.

Finally, enter a description of what you have done in the "**Edit summary**" field and click on the "**Save**" button. Wasn't that easy? Thanks for helping to improve Wikipedia!
