+  <h2 id="data-concerns">Data Concerns</h2>
+  <p>The following are some of the requirements that the data in your file
+    <strong>MUST</strong> fulfil before it is considered valid for this system:
+  </p>
+
+  <ol>
+    <li>File headings
+      <ul>
+	<li>The first row in the file should contains the headings. The number of
+	  headings in this first row determines the number of columns expected for
+	  all other lines in the file.</li>
+	<li>Each heading value in the first row MUST appear in the first row
+	  <strong>ONE AND ONLY ONE</strong> time</li>
+	<li>The strain headers in your first row will be against a source of truth
+	  (<a href="https://gitlab.com/fredmanglis/gnqc_py/-/blob/main/etc/strains.csv"
+	      title="list of expected strains">see strains.csv [1.7M]</a>).<br />
+	  Pick the strain names from the <strong>'Name'</strong> and
+	  <strong>'Name2'</strong> fields.</li>
+      </ul>
+    </li>
+
+    <li>Data
+      <ol>
+	<li><strong>NONE</strong> of the data cells/fields is allowed to be empty.
+	  All fields/cells <strong>MUST</strong> contain a value.</li>
+	<li>The first column of the data rows will be considered a textual field,
+	  holding the "identifier" for that row<li>
+	<li>Except for the first column/field for each data row,
+	  <strong>NONE</strong> of the data columns/cells/fields should contain
+	  spurious characters like `eeeee`, `5.555iloveguix`, etc...<br />
+	  All of them should be decimal values</li>
+	<li>decimal numbers must conform to the following criteria:
+	  <ul>
+	    <li>when checking an average file decimal numbers must have exactly three
+	      decimal places to the right of the decimal point.</li>
+	    <li>when checking a standard error file decimal numbers must have six or
+	      greater decimal places to the right of the decimal point.</li>
+	    <li>there must be a number to the left side of the decimal place
+	      (e.g. 0.55555 is allowed but .55555 is not).<li>
+	  </ul>
+	</li>
+      </ol>
+    </li>
+  </ol>
+
+  
+  <h2 id="file-types">Supported File Types</h2>
+  We support the following file types:
+
+  <ul>
+    <li>Tab-Separated value files (.tsv)
+      <ul>
+	<li>The <strong>TAB</strong> character is used to separate the fields of each
+	  column</li>
+	<li>The values of each field <strong>ARE NOT</strong> quoted.</li>
+	<li>Here is an
+	  <a href="https://gitlab.com/fredmanglis/gnqc_py/-/blob/main/tests/test_data/no_data_errors.tsv">
+	    example file</a> with a single data row.</li>
+      </ul>
+    </li>
+    <li>.txt files: Content has the same format as .tsv file above</li>
+    <li>.zip files: each zip file should contain
+      <strong>ONE AND ONLY ONE</strong> file of the .tsv or .txt type above.
+      <br />Any zip file with more than one file is invalid, and so is an empty
+      zip file.</li>
+  </ul>
