-As a research student, a proportion of your time will be devoted to writing science in a formal academic style. There are many resources that will help you to write your thesis, such as [Writing your thesis](https://www.mpls.ox.ac.uk/training/resources-for-researcher-and-career-development/ ompleting-your-dphil/writing-up-your-thesis), [Completing your doctorate](https://www.vitae.ac.uk/doing-research/doing-a-doctorate/completing-your-doctorate), [Essay and dissertation writing skills](https://www.ox.ac.uk/students/academic/guidance/skills/essay) and also other [resources for new students](https://cameralab.eng.ox.ac.uk/resources_new_students.html).

-My students have found very helpful to use the LaTeX typesetting system to write reports, theses, journal papers or other academic documents. You can write your LaTeX documents from scratch, however, it is often easier to start with an already written class template. This way you can focus on (as your supervisor expects) writing about your exciting research contributions, rather than spending time formatting your document or applying other cosmetic changes that just distract the reader.

 The OxEngThesis class is based on the [memoir](https://ctan.org/pkg/memoir) package, with the addition of several other packages and extra features useful to format a typical academic document. The main class file is [oxengthesis.cls](oxengthesis.cls). One sample source file is provided: [sample_dphil_thesis.tex](sample_dphil_thesis.tex) to get you started writing your thesis. You can check the [sample_dphil_thesis-sample_output.pdf](sample_dphil_thesis-sample_output.pdf) file to view an example of the output PDF document for a doctoral thesis.
 
-This tutorial summarises some of the features available in the OxEngThesis class. Take a look at the [oxengthesis.cls](oxengthesis.cls) file and the [sample_dphil_thesis.tex](sample_dphil_thesis.tex) source file for a more complete overview. Additionally, this tutorial is replicated as "Chapter 0 The OxEngThesis LaTeX class" in the [sample_dphil_thesis-sample_output.pdf](sample_dphil_thesis-sample_output.pdf), so you can view examples of the LaTeX syntax to write your document.

 ## LaTeX editors
 
 
-There are several editors available that will make your life easier when writing LaTeX documents and, ultimately, generating the final PDF file (a.k.a compiling the LaTeX source files). For macOS, [Texifier](https://www.texifier.com) works really well. Good editors for Linux are [Kile](https://apps.kde.org/en-gb/kile) and [TeXMaker](https://www.xm1math.net/texmaker). I don't use Microsoft Windows. If you know what software is good for this operating system, let me know so I cand add it to my recommendaiton list.
