+# pyenv-link
+A [pyenv](https://github.com/pyenv/pyenv) plugin for linking Python installations and virtual environments into your pyenv root.
+
+This plugin recommends the [pyenv-virtualenv](https://github.com/pyenv/pyenv-virtualenv/) plugin.
+
+## Usage
+
+Make an arbitrary virtualenv available through pyenv. This automatically guesses a fitting name from the prompt, the directory name or the location of the venv.
+
+```console
+$ pyenv link version .venv
+Linked new version named myproject
+```
+
+You can also specify a name to use for the venv.
+
+```console
+$ pyenv link version .venv myname
+Linked new version named myname
+```
+
+The same command can give a platform-specific binary installation a shorter name:
+
+```console
+$ pyenv link version "$(pyenv root)/versions/3.13.14-linux-x86_64" 3.13.14
+Linked new version named 3.13.14
+```
+
+Now you can make pyenv activate/use the venv automatically:
+
+```console
+$ pyenv local myproject
+```
