+`Viv` is a standalone dependency-free `venv` creator (just needs python + pip).
+`Viv` helps you ignore silly things like managing temporary or rarely used virtual environments,
+while still unleashing the full power of python scripting with it's entire ecosystem at your disposal.
+
+`Viv`'s uncompromising insistence on portability means that it will always,
+only use the standard library and never exceed a single script.

+# Installation
+
+## Automated
+
+Run the below command to install `viv`.
+
+```sh
+python3 <(curl -fsSL viv.dayl.in/viv.py) manage install
+```
+
+To access `viv` from within scripts you should add its location to your `PYTHONPATH`.
+By default `viv` will be installed to `$XDG_DATA_HOME/viv` or `~/.local/share/viv`,
+and symlinked to `$XDG_BIN_HOME` or `~/.local/bin/.`
+You can customize these locations at install with with `--src` and `--cli` respectively.
+
+```sh
+export PYTHONPATH="$PYTHONPATH:$HOME/.local/share/viv"
+# or
+export PYTHONPATH="$PYTHONPATH:$(viv manage show --pythonpath)"
+```
+
+:::{note}
+You can install an older version by specifying  `--ref`
+:::
+
+## Manual
+
+Viv is a single standalone script meaning all that's really necessary is
+that it exists locally and is appropriately added to your path.
+You can get the latest stable version from [here](https://viv.dayl.in/viv.py)
+or from [github](https://github.com/daylinmorgan/viv/blob/latest/src/viv/viv.py).
+
+Must be added to your `$PATH` for use as a CLI app and `$PYTHONPATH` for uses as a python module.
+
+## Never
+
+Viv is a standalone script accessible at `https://viv.dayl.in/viv.py`
+meaning it's not strictly necessary you every actually install it.
+Every instance of the `viv` CLI can be seamlessly replaced with `python3 <(curl -fsSL viv.dayl.in/viv.py)`.
+
+## PyPI Options (Not Recommended)
+
+Why is this *not recommended?*
+Mainly because `viv` is all about hacking your `sys.path`.
+Placing it in its own virtual environment
+or installing in a user site directory may complicate this endeavor.
+
+```sh
+pip install viv
+# or
+pipx install viv
+```
+ 
+*Note*: If installed by `pipx`, it should still be possible to
+use `viv` as a module by adding it to the `$PYTHONPATH`.
+See above for more info.

+# Usage
+
+Viv works by ensuring scripts or a given
+command are run in an appropriate environment with all specified dependencies.
+
+:::{tip}
+`viv` is a single script and available at `viv.dayl.in/viv.py`
+meaning every instance of `viv` in these examples could be `python3 <(curl -fsSL viv.dayl.in/viv.py)`
+:::
+
+## Run CLI Apps
+
+Run a python app that provides an entrypoint and separate args with `--`:
+
+```sh
+viv run frogmouth -- gh daylinmorgan/viv
+```
+
+Run a python module use the `-b/--bin` flag and specify `python`:
+
+```sh
+viv run rich -b python -- -m rich
+```
+
+Make an ephemeral `jupyter` environment with your needed deps:
+
+```sh
+viv run jupyter pandas -r requirements-dev.txt -- notebook
+```
+
+Generate an executable shell script that will on demand create a vivenv as needed:
+
+```sh
+viv shim ruff
+```
+
+Output:
+```python
+#!/usr/bin/env python3
+# AUTOGENERATED by viv (v2023.1003)
+# see `python3 <(curl -fsSL viv.dayl.in/viv.py) --help`
+
+import subprocess
+import sys
+
+if __name__ == "__main__":
+    vivenv = __import__("viv").use("ruff") # noqa
+    sys.exit(subprocess.run([vivenv / "bin" / "ruff", *sys.argv[1:]]).returncode)
+```
+
+## Run Python Scripts
+
+It's possible to use the `viv` CLI to run a python script.
+There are several options for invoking a script.
+
+Using the interpreter:
+```sh
+viv run rich typer -b python -- ./cli.py --help
+```
+
+Using `-s/--script`:
+```sh
+viv run rich typer -s ./cli.py -- --help
+# or with a remote script
+viv run rich -s https://raw.githubusercontent.com/Textualize/rich/master/examples/fullscreen.py
+```
+
+If `viv` is available on your path it's possible to
+invoke it with embedded metadata thanks to shebangs:
+
+```python
+#!/usr/bin/env -S viv run --keep --script
+# /// script
+# requires-python = ">3.10"
+# dependencies = [
+#   "matplotlib",
+#   "pandas"
+# ]
+# ///
+```
+
+:::{note}
+If using a shebang on a python script `-s/--script` must be the last argument
+:::
+
+:::{seealso}
+Check out [PEP723](https://peps.python.org/pep-0723/) for more info about inline script metadata.
+:::
+
+In any python script with external dependencies you can also add this line prior to imports
+to automate `vivenv` creation and installation of dependencies.
+
+```python
+__import__("viv").use("click")
+```
+
+If your dependencies are sensitive to the version of python
+(numpy, cpython-based apps, etc. ) then you can specify `track_exe`.
+Which will lead to `viv` creating a unique vivenv based on the detected python executable.
+
+```python
+__import__("viv").use("numpy", track_exe=True)
+```
+
+If you'd like to pin your dependencies to a resolved environment you
+can use the convenience command `viv freeze` to output a list of pinned packages.
+
+Command:
+```sh
+viv freeze rich typer
+```
+
+Output:
+```python
+__import__("viv").use("rich==13.7.0", "typer==0.9.0", "click==8.1.7", "markdown-it-py==3.0.0", "Pygments==2.17.2", "typing_extensions==4.9.0", "mdurl==0.1.2") # noqa
+```
+
+Additionally, you can make this work regardless of `PYTHONPATH` by using `--path`.
+
+Command:
+```sh
+viv freeze rich typer --path rel
+```
+
+Output:
+```python
+__import__("sys").path.append(__import__("os").path.expanduser("~/.local/share/viv/"))  # noqa
+__import__("viv").use("rich==13.7.0", "typer==0.9.0", "click==8.1.7", "markdown-it-py==3.0.0", "Pygments==2.17.2", "typing_extensions==4.9.0", "mdurl==0.1.2") # noqa
+```
+
+## Manage Viv
+
+### Interacting with the viv cache
+
+Depending on how you invoke `viv`, it will persist it's virtual environments (vivenvs).
+To see all currently existing vivenvs use can use `viv list`.
+
+Viv will attempt to track any usages of the
+vivenvs including the scripts that invoke them.
+
+You can remove any existing vivenvs using `viv env remove`:
+
+```sh
+viv env remove d4b342b3
+```
+
+To get more information about vivenvs you can use `viv list --verbose` or `viv env info <hash>`
+
+:::{note}
+For commands that expect a vivenv hash/name you can use as few characters as you
+as you like and `viv` will match it against the existing vivenvs in the cache.
+:::
+
+You can list vivenvs given a criteria using `--filter` for example:
+
+Created before 2024-01-01:
+```sh
+viv list --filter "created-before:2024-01-01"
+```
+
+Associated with a particular file:
+```sh
+viv list --filter "files:./script.py"
+```
+
+Or no files:
+```sh
+viv list --filter "files:None"
+```
+
+:::{note}
+`--filter "files:None"` will also apply to vivenvs
+in which the original file is no longer on the disk
+:::
+
+The available filtering criteria are `accessed-after`,
+`accessed-before`, `created-before`, `created-after`, `spec` and `files`.
+
+To remove all `vivenvs` you can use the below command:
+
+```sh
+viv env remove $(viv list -q)
+```
+
+To remove `viv` all together you can use the included `purge` command:
+
+```sh
+python3 <(curl -fsSL viv.dayl.in/viv.py) manage purge
+```
+
+## Bonus: `viv` standalone 
+
+`--standalone` will auto-generate a mini function version of `viv` to accomplish the same basic task as using a local copy of `viv`.
+After generating this standalone `shim` you can freely use this script across unix machines which have `python>3.8`.
+See [examples/black](https://github.com/daylinmorgan/viv/blob/dev/examples/black) for output of below command.
+
+`viv freeze` also supports `--standalone`
+
+```sh
+python3 <(curl -fsSL viv.dayl.in/viv.py) shim black -o ./black --standalone --freeze
+```
