# Annotation NeuTu allows you to annotate an individual body (body annotation) or add a point annotation at any location. A body annotation is a set of information that describes a body, such as its proofreading status and its neuron name. A point annotation is associated with a unique location. There are several kinds of point annotation: * Bookmarks: this category is mainly for flagging an interesting location or something that should be examined later. * Todos: they are similar to bookmarks, but mainly for proofreading purposes as the name suggests. Unlike bookmarks, they are associated with bodies. * Synapses: synapse annotations, including pre-synaptic (T-Bar) and post-synaptic (PSD) elements. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://janelia-flyem.gitbook.io/neutu/annotation.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
