+## Environment Variables Set By Pixi
+
+The following environment variables are set by Pixi, when using the `pixi run`, `pixi shell`, or `pixi shell-hook` command:
+
+- `PIXI_PROJECT_ROOT`: The root directory of the project.
+- `PIXI_PROJECT_NAME`: The name of the project.
+- `PIXI_PROJECT_MANIFEST`: The path to the manifest file (`pixi.toml`).
+- `PIXI_PROJECT_VERSION`: The version of the project.
+- `PIXI_PROMPT`: The prompt to use in the shell, also used by `pixi shell` itself.
+- `PIXI_ENVIRONMENT_NAME`: The name of the environment, defaults to `default`.
+- `PIXI_ENVIRONMENT_PLATFORMS`: Comma separated list of platforms supported by the project.
+- `CONDA_PREFIX`: The path to the environment. (Used by multiple tools that already understand conda environments)
+- `CONDA_DEFAULT_ENV`: The name of the environment. (Used by multiple tools that already understand conda environments)
+- `PATH`: We prepend the `bin` directory of the environment to the `PATH` variable, so you can use the tools installed in the environment directly.
+- `INIT_CWD`: ONLY IN `pixi run`: The directory where the command was run from.
+
+!!! note
+    Even though the variables are environment variables these cannot be overridden. E.g. you can not change the root of the project by setting `PIXI_PROJECT_ROOT` in the environment.

 ## Solving environments
 
 When you run a command that uses the environment, Pixi will check if the environment is in sync with the `pixi.lock` file.
