 # LaTeX2Image
 
-A Node.js web application that allows LaTeX math equations to be converted to PNG/JPG/SVG images.
+![Image](screenshots/main.png)
+
+A Node.js web application that allows LaTeX math equations to be entered and converted to PNG/JPG/SVG images.
+
+For each conversion, an isolated Docker container with a LaTeX installation is started; it compiles the generated .tex file and converts it to an SVG vector image. If required, the SVG file is then converted to a raster image format for PNG/JPG.
+
+Bootstrap and jQuery are used in the web interface, with AJAX calls made to the conversion API endpoint.
+
+## Dependencies
+
+### Docker
+
+Docker CE with [non-root user support](https://docs.docker.com/install/linux/linux-postinstall/#manage-docker-as-a-non-root-user).
+
+### [latex-docker](https://github.com/blang/latex-docker)
+
+Docker image containing the required LaTeX packages preinstalled.
+Pull the image:
+
+```
+docker pull blang/latex:ubuntu
+```
+
+### [Node.js](https://nodejs.org/en/download/)
+
+Version 6 and onwards should suffice; I made use of v10.14.2.
+
+### Global Node.js packages
+
+#### [svgexport](https://www.npmjs.com/package/svgexport)
+
+```
+npm install svgexport -g
+```
+
+#### [imagemin-cli](https://www.npmjs.com/package/imagemin-cli)
+
+```
+npm install imagemin-cli -g
+```
+
+### Local Node.js packages
+
+After cloning or downloading this project, run
+
+```
+cd latex2image-web/
+npm install
+```
+
+## Usage
+
+To run:
+
+```
+node app.js
+```
+
+The web interface will be accessible at `http://127.0.0.1:3001` by default. The port and HTTP URL can be modified inside `app.js`.
+
+Enter a LaTeX equation, for example `\frac{a}{b}`, and press Convert. The result will be displayed below.
+
+## Notes
+
+* The directories `temp/` and `output/` will be generated automatically inside the `latex2image-web/` directory upon first launch.
+* `temp/` stores temporary `.tex`, `.dvi`, and `.svg` files during compilation.
+* Final output images are stored in `output/`.
