+This repository holds a minimal installer for conda on platforms that conda-forge supports but that aren't supported by [Miniconda]((https://docs.conda.io/en/latest/miniconda.html).
 
-This work is still very experimental

-Features of this repository to implement:
-- [ ] Automatic build of constructor
-    - [ ] aarch64 -- https://github.com/conda-forge/miniforge/pull/1
-    - [ ] Other architectures???
-- [ ] Automatic upload of constructor results
-    - [ ] Test: https://github.com/conda-forge/miniforge/pull/1
-- [ ] Automatic testing of constructor on Ubuntu 18.04 docker image
-- [ ] Integration with conda-forge's developer documentation
-- [ ] Integration with conda-forge's official site
-- [ ] Upstream to Anaconda???
+## Download
+
+Miniforge installers are available here: https://github.com/conda-forge/miniforge/releases.
+
+## Supported architectures
+
+- `aarch64` (also called `arm64`)
+
+## Features
+
+- [X] Automatic build of constructor.
+- [X] Automatic upload of constructor results.
+- [X] Automatic testing of constructor.
+- [ ] Integration with conda-forge's developer documentation.
+- [ ] Integration with conda-forge's official site.
+- [ ] Upstream to Anaconda ?
+
+## Testing
+
+After construction on Travis, the installer is tested against a range of distribution that match the installer architecture (`$ARCH`). For example when architecture is `aarch64`, the constructed installer is tested against:
+
+- Centos 7
+- Debian Buster (10)
+- Ubuntu 16.04
+- Ubuntu 18.04
+- Ubuntu 19.10
+
+## Usage
+
+Installers are built and uploaded via Travis but if you want to construct your own Miniforge installer, here is how:
+
+```bash
+# Configuration
+export ARCH=aarch64
+export DOCKERIMAGE=condaforge/linux-anvil-aarch64
+export QEMU_BINARY=qemu-aarch64-static
+
+bash build_miniforge.sh
+```
+
+## Release
+
+To release a new version of Miniforge:
+
+- Open a new PR.
+- Edit [`Miniforge3/construct.yaml`](./Miniforge3/construct.yaml).
+  - Update the `version` tag to: `$CONDA_VERSION-$BUILD_NUMBER`. For example, `4.7.11-0`.
+  - Update `conda` version in the `specs` section to `$CONDA_VERSION`.
+  - Update `python` version in the `specs` section to the Python version used in [Miniconda](https://repo.anaconda.com/miniconda/).
+- Once CI is happy, merge into `master`.
+- Tag `HEAD` to `$CONDA_VERSION-$BUILD_NUMBER` and push the tag:
+  - `git tag $CONDA_VERSION-$BUILD_NUMBER`
+  - `git push origin master --tags`
