+
+A specification for pythonic filesystems.
+
+## Install
+
+```bash
+pip install fsspec
+```
+
+would install the base fsspec. Various optionally supported features might require specification of custom
+extra require, e.g. `pip install fsspec[ssh]` will install dependencies for `ssh` backends support.
+Use `pip install fsspec[full]` for installation of all known extra dependencies.
+
+Up-to-date package also provided through conda-forge distribution:
+
+```bash
+conda install -c conda-forge fsspec
+```
+
+
+## Purpose
+
+To produce a template or specification for a file-system interface, that specific implementations should follow,
+so that applications making use of them can rely on a common behaviour and not have to worry about the specific
+internal implementation decisions with any given backend. Many such implementations are included in this package,
+or in sister projects such as `s3fs` and `gcsfs`.
+
+In addition, if this is well-designed, then additional functionality, such as a key-value store or FUSE
+mounting of the file-system implementation may be available for all implementations "for free".
+
+## Documentation
+
+Please refer to [RTD](https://filesystem-spec.readthedocs.io/en/latest/?badge=latest)
+
+## Develop
+
+fsspec uses GitHub Actions for CI. Environment files can be found
+in the "ci/" directory. Note that the main environment is called "py38",
+but it is expected that the version of python installed be adjustable at
+CI runtime. For local use, pick a version suitable for you.
+
+### Testing
+
+Tests can be run in the dev environment, if activated, via ``pytest fsspec``.
+
+The full fsspec suite requires a system-level docker, docker-compose, and fuse
+installation. If only making changes to one backend implementation, it is
+not generally necessary to run all tests locally.
+
+It is expected that contributors ensure that any change to fsspec does not
+cause issues or regressions for either other fsspec-related packages such
+as gcsfs and s3fs, nor for downstream users of fsspec. The "downstream" CI
+run and corresponding environment file run a set of tests from the dask
+test suite, and very minimal tests against pandas and zarr from the
+test_downstream.py module in this repo.
+
+### Code Formatting
+
+fsspec uses [Black](https://black.readthedocs.io/en/stable) to ensure
+a consistent code format throughout the project.
+Run ``black fsspec`` from the root of the filesystem_spec repository to
+auto-format your code. Additionally, many editors have plugins that will apply
+``black`` as you edit files. ``black`` is included in the ``tox`` environments.
+
+Optionally, you may wish to setup [pre-commit hooks](https://pre-commit.com) to
+automatically run ``black`` when you make a git commit.
+Run ``pre-commit install --install-hooks`` from the root of the
+filesystem_spec repository to setup pre-commit hooks. ``black`` will now be run
+before you commit, reformatting any changed files. You can format without
+committing via ``pre-commit run`` or skip these checks with ``git commit
+--no-verify``.

+        A pyasn1 type object to act as a template guiding the decoder.
+        Depending on the ASN.1 structure being decoded, `asn1Spec` may
+        or may not be required. One of the reasons why `asn1Spec` may

+        tagging mode.
+
+    Yields
+    ------
+    : :py:class:`~pyasn1.type.base.PyAsn1Item`, :py:class:`~pyasn1.error.SubstrateUnderrunError`
+        Decoded ASN.1 object (possibly, nested) or

+        insufficient BER/CER/DER serialization on input to fully recover ASN.1
+        objects from it.
+        
+        In the latter case the caller is advised to ensure some more data in
+        the input stream, then call the iterator again. The decoder will resume
+        the decoding process using the newly arrived data.
+
+        The `context` property of :py:class:`~pyasn1.error.SubstrateUnderrunError`
+        object might hold a reference to the partially populated ASN.1 object

+#: Takes BER octet-stream and decode it into an ASN.1 object
+#: (e.g. :py:class:`~pyasn1.type.base.PyAsn1Item` derivative) which
+#: may be a scalar or an arbitrary nested structure.
+#:
+#: Parameters
+#: ----------
+#: substrate: :py:class:`bytes`
+#:     BER octet-stream
+#:
+#: Keyword Args
+#: ------------
+#: asn1Spec: any pyasn1 type object e.g. :py:class:`~pyasn1.type.base.PyAsn1Item` derivative
+#:     A pyasn1 type object to act as a template guiding the decoder. Depending on the ASN.1 structure
+#:     being decoded, *asn1Spec* may or may not be required. Most common reason for
+#:     it to require is that ASN.1 structure is encoded in *IMPLICIT* tagging mode.
+#:
+#: Returns
+#: -------
+#: : :py:class:`tuple`
+#:     A tuple of pyasn1 object recovered from BER substrate (:py:class:`~pyasn1.type.base.PyAsn1Item` derivative)
+#:     and the unprocessed trailing portion of the *substrate* (may be empty)
+#:
+#: Raises
+#: ------
+#: ~pyasn1.error.PyAsn1Error, ~pyasn1.error.SubstrateUnderrunError
+#:     On decoding errors
+#:
+#: Notes
+#: -----
+#: This function is deprecated. Please use :py:class:`Decoder` or
+#: :py:class:`StreamingDecoder` class instance.
+#:
+#: Examples
+#: --------
+#: Decode BER serialisation without ASN.1 schema
+#:
+#: .. code-block:: pycon
