Disclaimer: I am associated with the initiative (
codelearn.org) & this project has my vested interest. If anybody feels that the project is approved for a lower budget (technically, I have no prior experience of proof reading), feel free to write back to me or the group. We follow 'completely open & receptive' culture on this platform.
The project requires somebody with some level of proof reading skills (good written english). The rest is on the project page itself.
