+# Nextstrain repository for measles virus
 
-This is the [Nextstrain](https://nextstrain.org) build for measles virus, visible at
-[nextstrain.org/measles](https://nextstrain.org/measles).
+This repository contains two workflows for the analysis of measles virus data:
 
-The build encompasses fetching data, preparing it for analysis, doing quality
-control, performing analyses, and saving the results in a format suitable for
-visualization (with [auspice][]).  This involves running components of
-Nextstrain such as [augur][].
+- [`ingest/`](./ingest) - Download data from GenBank, clean and curate it
+- [`phylogenetic/`](./phylogenetic) - Filter sequences, align, construct phylogeny and export for visualization
 
-All measles-specific steps and functionality for the Nextstrain pipeline should be
-housed in this repository.
+Each folder contains a README.md with more information. The results of running both workflows are publicly visible at [nextstrain.org/measles](https://nextstrain.org/measles).
 
-[![Build Status](https://github.com/nextstrain/measles/actions/workflows/ci.yaml/badge.svg?branch=main)](https://github.com/nextstrain/measles/actions/workflows/ci.yaml)
+## Installation
 
-## Usage
+Follow the [standard installation instructions](https://docs.nextstrain.org/en/latest/install.html) for Nextstrain's suite of software tools.
 
-If you're unfamiliar with Nextstrain builds, you may want to follow our
-[quickstart guide][] first and then come back here.
+## Quickstart
 
-The easiest way to run this pathogen build is using the [Nextstrain
-command-line tool][nextstrain-cli]:
+Run the default phylogenetic workflow via:
+```
+cd phylogenetic/
+nextstrain build .
+nextstrain view .
+```
 
-    nextstrain build .
+## Documentation
 
-See the [nextstrain-cli README][] for how to install the `nextstrain` command.
-
-Alternatively, you should be able to run the build using `snakemake` within a
-suitably-configured local environment.  Details of setting that up are not yet
-well-documented, but will be in the future.
-
-Build output goes into the directories `data/`, `results/` and `auspice/`.
-
-Once you've run the build, you can view the results in auspice:
-
-    nextstrain view auspice/
-
-
-## Configuration
-
-Configuration takes place entirely with the `Snakefile`. This can be read top-to-bottom, each rule
-specifies its file inputs and output and also its parameters. There is little redirection and each
-rule should be able to be reasoned with on its own.
-
-<!--
-### fauna / RethinkDB credentials
-
-This build starts by pulling sequences from our live [fauna][] database (a RethinkDB instance). This
-requires environment variables `RETHINK_HOST` and `RETHINK_AUTH_KEY` to be set.
--->
-
-If you don't have access to our https endpoints, you can run the build using the
-example data provided in this repository.  Before running the build, copy the
-example sequences into the `data/` directory like so:
-
-    mkdir -p data/
-    cp example_data/* data/.

+This build starts by pulling preprocessed sequence and metadata files from:
