We will now look at how to add images to a L a T e X document. On Overleaf, you will first have to upload the images. L a T e X can not manage images by itself, so you will need to use a package.
Packages can be used to change the default look of your L a T e X document, or to allow more functionalities. In this case, you need to include an image in our document, so you should use the graphicx package. Here universe is the name of the file containing the image without the extension, then universe.
PNG becomes universe. The file name of the image should not contain white spaces nor multiple dots. Note: The file extension is allowed to be included, but it's a good idea to omit it.
If the file extension is omitted it will prompt LaTeX to search for all the supported formats. It is also usually recommended to use lowercase letters for the file extension when uploading image files. For more details see the section about generating high resolution and low resolution images. Images can be captioned, labelled and referenced by means of the figure environment as shown below:.
When placing images in a L a T e X document, we should always put them inside a figure environment or similar so that L a T e X will position the image in a way that fits in with the rest of your text.
Note: If you are using captions and references on your own computer, you will have to compile the document twice for the references to work. Overleaf will do this for you automatically. Lists are very simple to create in L a T e X. You can create lists using different list environments.
Environments are sections of our document that you want to present in a different way to the rest of the document. There are two main different types of lists, ordered lists and unordered lists. Each will use a different environment. Unordered lists are produced by the itemize environment.
By default the individual entries are indicated with a black dot, so-called bullet. The text in the entries may be of any length. Ordered list have the same syntax inside a different environment. We make ordered lists using the enumerate environment:.
The enumerate labels consists of sequential numbers starting at one. One of the main advantages of L a T e X is the ease at which mathematical expressions can be written. L a T e X allows two writing modes for mathematical expressions: the inline mode and the display mode.
The first one is used to write formulas that are part of a text. The second one is used to write expressions that are not part of a text or paragraph, and are therefore put on separate lines. Let's see an example of the inline mode:. They all work and the choice is a matter of taste. Many math mode commands require the amsmath package, so be sure to include it when writing math. An example is shown below of some basic math mode commands.
The possibilities with math in L a T e X are endless and it is impossible to list them all here. Be sure to check out our other articles on. We will now look at how to write abstracts, as well as how to format a L a T e X document into different chapters, sections and paragraphs. In scientific documents it's a common practice to include a brief overview of the main subject of the paper. In L a T e X there's the abstract environment for this. The abstract environment will put the text in a special format at the top of your document.
When writing the contents of your document, if you need to start a new paragraph you must hit the "Enter" key twice to insert a double blank line. Notice that L a T e X automatically indents paragraphs.
You can find more information in the Paragraphs and new lines article. Commands to organize a document vary depending on the document type, the simplest form of organization is the sectioning, available in all formats. The basic levels of depth are listed below:. For a more complete discussion about the document structure see the article about sections and chapters. The tabular environment is the default L a T e X method to create tables.
This tells L a T e X that there will be three columns and that the text inside each one of them must be centred. You can also use r to align the text to the right and l for left alignment.
There must always be one less alignment symbol in each line than the number of columns. We wrap the entire table inside the center environment so that it will appear in the center of the page. The tabular environment is more flexible, you can put separator lines in between each column. Creating tables in L a T e X can be a bit tricky sometimes, so you may want to use the TablesGenerator. You can caption and reference tables in much the same way as images.
The only difference is that instead of the figure environment, you use the table environment. Sections, subsections and chapters are automatically included in the table of contents. Have you checked our knowledge base? If you use a TeX distribution then it will include a version of LaTeX so this will probably make things easier for you; but you may have a reason not to do this.
Anyone can access it and download the files, but submission is restricted to team members. If you are familiar with Git you can also clone the repository using the command line or your favorite Git fontend tool, e. Alternatively, you can do a Subversion checkout from the command line, e. Note: If you had bookmarked the old SVN repository please update that bookmark to the new GIT repository as we have finally removed it.
While we appreciate contributions, we think that for the core LaTeX software pull requests are usually not a good approach unless the change has be already discussed and agreed upon. The stability of LaTeX is very important and this means that changes to the kernel are necessarily very conservative. It also means that a lot of discussion has to happen before any changes are made.
So if you do decide to post a pull request, please bear this in mind: we do appreciate ideas, but cannot always integrate them into the kernel and it is quite likely that we reject updates made in this way. If you want to discuss a possible contribution before or instead of making a pull request, we suggest you raise the topic first on the LATEX-L list or drop a line to the team.
