+## Python library for Apache Arrow
+
+[![pypi](https://img.shields.io/pypi/v/pyarrow.svg)](https://pypi.org/project/pyarrow/) [![conda-forge](https://anaconda.org/conda-forge/pyarrow/badges/version.svg)](https://anaconda.org/conda-forge/pyarrow)
+
+This library provides a Python API for functionality provided by the Arrow C++
+libraries, along with tools for Arrow integration and interoperability with
+pandas, NumPy, and other software in the Python ecosystem.
+
+## Installing
+
+Across platforms, you can install a recent version of pyarrow with the conda
+package manager:
+
+```shell
+conda install pyarrow -c conda-forge
+```
+
+On Linux, macOS, and Windows, you can also install binary wheels from PyPI with
+pip:
+
+```shell
+pip install pyarrow
+```
+
+If you encounter any issues importing the pip wheels on Windows, you may need
+to install the latest [Visual C++ Redistributable for Visual Studio][3].
+
+## Development
+
+See [Python Development][2] in the documentation subproject.
+
+### Building the documentation
+
+See [documentation build instructions][1] in the documentation subproject.

+/// ADLS Gen2 isn't a dedicated service or account type. It's a set of capabilities that
+/// support high throughput analytic workloads, built on Azure Blob Storage. All the data
+/// ingested via the ADLS Gen2 APIs is persisted as blobs in the storage account.
+/// ADLS Gen2 provides filesystem semantics, file-level security, and Hadoop
+/// compatibility. ADLS Gen1 exists as a separate object that will retired on 2024-02-29
+/// and new ADLS accounts use Gen2 instead.
+///
+/// ADLS Gen2 and Blob APIs can operate on the same data, but there are
+/// some limitations [3]. The ones that are relevant to this
+/// implementation are listed here:
+///
+/// - You can't use Blob APIs, and ADLS APIs to write to the same instance of a file. If
+///   you write to a file by using ADLS APIs then that file's blocks won't be visible
+///   to calls to the GetBlockList Blob API. The only exception is when you're
+///   overwriting.
+/// - When you use the ListBlobs operation without specifying a delimiter, the results
+///   include both directories and blobs. If you choose to use a delimiter, use only a
+///   forward slash (/) \--- the only supported delimiter.
+/// - If you use the DeleteBlob API to delete a directory, that directory is deleted only
+///   if it's empty. This means that you can't use the Blob API delete directories
+///   recursively.

+/// \brief GCS-backed FileSystem implementation.
+///
+/// GCS (Google Cloud Storage - https://cloud.google.com/storage) is a scalable object
+/// storage system for any amount of data. The main abstractions in GCS are buckets and
+/// objects. A bucket is a namespace for objects, buckets can store any number of objects,
+/// tens of millions and even billions is not uncommon.  Each object contains a single
+/// blob of data, up to 5TiB in size.  Buckets are typically configured to keep a single
+/// version of each object, but versioning can be enabled. Versioning is important because
+/// objects are immutable, once created one cannot append data to the object or modify the
+/// object data in any way.
+///
+/// GCS buckets are in a global namespace, if a Google Cloud customer creates a bucket
+/// named `foo` no other customer can create a bucket with the same name. Note that a
+/// principal (a user or service account) may only list the buckets they are entitled to,
+/// and then only within a project. It is not possible to list "all" the buckets.
+///
+/// Within each bucket objects are in flat namespace. GCS does not have folders or
+/// directories. However, following some conventions it is possible to emulate
+/// directories. To this end, this class:
+///
+/// - All buckets are treated as directories at the "root"
+/// - Creating a root directory results in a new bucket being created, this may be slower
+///   than most GCS operations.
+/// - The class creates marker objects for a directory, using a metadata attribute to
+///   annotate the file.
+/// - GCS can list all the objects with a given prefix, this is used to emulate listing
+///   of directories.
+/// - In object lists GCS can summarize all the objects with a common prefix as a single
+///   entry, this is used to emulate non-recursive lists. Note that GCS list time is
+///   proportional to the number of objects in the prefix. Listing recursively takes
+///   almost the same time as non-recursive lists.
